Folks may be familiar with our HalloWing M4 (https://www.adafruit.com/product/4300) fancy eyeballs demo code - it's very dependent on the wired-up hardware. But of course, with our new round displays (https://www.adafruit.com/product/6178), we wanted to try wiring one up to see how it looks. That ended up being 2 days of hacking, but at least it's done now - we've refactored the code to support any SAMD51 board and any SPITFT display. It's not ready for publication yet; We juuuuuust got this working like 3 minutes ago... We want to abstract out the SAMD51-dependant parts so it could be run on chips like the ESP32 or RP2350 (https://www.adafruit.com/product/6055)!

There's nothing like hefting a brand new panel of PCBs, ready to be snapped-apart and tested! this board is a refresh of our Matrix Portal M4 board - SAMD51's are unavailable for the near future so it's a great excuse to do a redesign...here we've got an 8MB Flash + 2MB PSRAM S3 with wifi, bluetooth, and a parallel-driving peripheral that does a great job driving RGB LED Matrices. we also fixed a common request by adding mounting holes and a 2x8 IDC connector up top so you can either plug directly into a panel or use a cable. #adafruit #electronics #Espressif Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- @EspressifSystems

We're slowly but surely trying to de-SAMD51'ify our product line since that chip has a 2024 ETA. a bummer because we really loved that chip but it's probably a good time to transition since it can be a year until we get some and even then, the dates have been pushed multiple times. so, first up is the matrix portal m4 https://www.adafruit.com/product/4745 ! instead of a samd51 + esp32, we've got a version with ESP32-S3 WROOM which has 8MB of flash, and 2MB of PSRAM. the S3 has a nice peripheral that can be used to drive these matricies very fast, and the 2 MB of PSRAM will make this possible to drive lots of panels! we kept the same outline shape and functionality, including the built in accelerometer, which makes this LED sand demo a quick port.

We're continuing on our quest to replace the brains of the Baby Einstein Take-a-Long Tunes toy with something that can play Autechre or Bjork. Since the last video, Mr Ladyada has scanned in the PCB so that we can start to trace the outlines. We used simple computer image editing software to delete the background, rotate it so its straight, and convert it to monochrome. After importing, we traced out the slots and holes so that our new PCB will be able to fit right in place. Now its time to spec some parts! Our big decision is what chipset to go with: we can't get SAMD21 or SAMD51's anymore, so our best bet is ESP32 series or RP2040. Since the case does not have a USB slot we have to have the USB port for programming on the inside and a few screws removed to do so. So we figured a WiFi-capable chip would be nice since then it could be programmed wirelessly. So we're gonna start with trying to place an ESP32-S2 (https://www.adafruit.com/?q=esp32-s2&sort=BestMatch) inside. For audio output we'll use the MAX98357 mono I2S amp (https://www.adafruit.com/product/3006) since the DAC on the -S2 isn't very good for audio playback. Now we just have to fit it all in and route the PCB!

We like to use our Pretty Pins generator to make lovely and *accurate* diagrams of dev boards. It starts with the Fritzing object (which is generated from the original Eagle files), and then cross references the Arduino and CircuitPython variant definition file to get the true pin names of each exposed pad and signal. Finally it looks up the multiplexing functionality for that gpio pin on the chip in a spreadsheet to generate the lovely label boxes. The pinmux spreadsheet has to be made by hand but we finally got around to doing the massive table used for the SAMD51 so we can now generate Pretty Pins for all SAMD51-based designs.

We churned through a big pile of testers and new designs this week: two IPS TFT displays with EYESPI connectors, the VL53L4CD time-of-flight sensor, the ESP32 QT Py, an OV2640/OV5640 camera breakout, and the ESP32-C3 QT Py. With a lot of our floppy work done and tested for both SAMD51 and RP2040, it's time to move from shugart 34 pin to Apple Disk ][ which uses a different 20 pin interface. The power supply and controlling technique is going to be different for this drive because to save costs they removed and simplified the drive control system. The Great Search - Positive to negative 12V power inverter for Apple 2 disk drive bias. https://www.digikey.com/short/5w04zzr2 The Apple Disk ][ drive is a converted Shugart drive that has three power supplies: 5V, +12V and -12V. The 5V and 12V are for the motor control. Negative 12V is a bit of a pain to generate, but thankfully the -12V seems to only be used for biasing a trim potentiometer. So, we don't need a lot of current. Still, we do need to generate -12V, let's take inspiration from the classic MAX232 RS232 driver chip to find a charge pump converter! #deskofladyada #thegreatsearch #adafruit Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

from ladyada "we had a lot of success with our retro-go port (even submitted a PR) and now we've got the NES emulator 'nofrendo' working. we're reaaaaally familiar with this emulator, having ported it to the SAMD51 a few years ago (see https://learn.adafruit.com/nes-emulator-for-arcada for deets). its a fairly portable emulator that can run many games. we popped in a micro SD card with a bunch of roms and had a go at playing some of our fav NES games: kid icarus, arkanoid, tetris and of course dragon warrior - which was the first rpg game i played on a console and was totally amazing (and paved the way for jrpgs like final fantasy, xenogears, legend of gaia, etc) i still think about farming those steel slimes... anyways! since the ips 1.3" tft is 240x240 pixels it does a pretty good job of being smol but fitting the 256x240 native resolution. you can either scale the output, or drop some pixels on the left and right. with audio and playback working this may the the smallest pixel-perfect nes gaming emulator ever made :) " #adafruit #nofrendo #retro Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

now that we have successful flux reads, its time to get flexible! we've swapped our SAMD51 feather board out for an RP2040 feather. not only is this feather a lovely pink shade, but it comes with a totally different chipset. oh no, do we need to start over completely with a new toolchain, timer configuration and dma library? nope! our code is hardware agnostic enough that with pin name tweaks and a couple ifdefs, we can use it just fine with greaseweazle again. so now our library has 2 chips it can use, very handy when there's a silicon shortage going round. next up, could we use the $4 raspberry pi pico board??? stay tuned :) YAY! floppy disk interfacing part 7, a floppy flux milestone! https://blog.adafruit.com/2022/01/01/yay-floppy-disk-interfacing-part6-a-floppy-flux-milestone/ https://youtu.be/IrSwMuFk-2c reading floppy disk data part 6, MFM sector decoding https://youtu.be/mE-77nEXbGc https://blog.adafruit.com/2022/01/01/reading-floppy-disk-data-part-6-mfm-sector-decoding/ reading raw floppy disk data part 5, at night the greaseweazles come https://blog.adafruit.com/2022/01/01/reading-raw-floppy-disk-data-part-5-at-night-the-greaseweazles-come/ https://youtu.be/e6v7Q4h5JBM interfacing with floppy disks at low level, part 4 https://blog.adafruit.com/2021/12/30/interfacing-with-floppy-disks-at-low-level-part-4/ https://youtu.be/a-zH9wdNwnE Reading floppy disk data, part 3! itsa pulse party https://blog.adafruit.com/2021/12/29/reading-floppy-disk-data-part-3-itsa-pulse-party/ https://youtu.be/kynoLRQpDnU Adding floppy disk support to CircuitPython, step 2 https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-2/ https://youtu.be/frnJ7pWr5Zg Adding floppy disk support to CircuitPython, step 1… https://blog.adafruit.com/2021/12/28/adding-floppy-disk-support-to-circuitpython-step-1/ https://youtu.be/ceyM6vYpT74 Adafruit Floppy is a project to make a flexible, full-stack, open source hardware/software device for reading, archiving, accessing and duplicating floppy disk media. It joins a family of open source hardware and software such as greaseweazle and fluxengine, and will attempt to increase the availability and accessibility of floppy disk controllers by: porting the greaseweazle / fluxengine firmware to Arduino so that it is less tied to specific hardware, adding firmware support for the RP2040 chip / low cost pico, adding hardware support for reading apple ii disks including index sensing, adding woz/a2r support to greaseweazle / fluxengine, and investigating analog flux data acquisition methods for repair of damaged disks. all of this with permissively licensed hardware and software so folks can re-create without licensing agreements, NDAs, or discussion. https://github.com/adafruit/Adafruit_Floppy #adafruit #floppy #raspberrypi Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Woo it is sweltering, which means we got to stay in and do a bunch of engineering. This week we spent a little time finishing up some languishing boards - Stemma QT version of the SCD40/SCD41 and IS31FL3741 chips - we wrote libraries for both as well! We also are dealing with a massive SAMD51 shortage by redesigning some recent boards like the Matrix Portal to be S2 only (so at least there's only one chip to source!) The Great Search - BSS138 Dual N-Channel FET Alternative Replacement https://www.digikey.com/short/5hh9bz4w We use hundreds of thousands of the famed dual BSS138 n-channel FET in every one of our breakouts - we use them for I2C level shifting on our breakouts and QT boards. But, this ultra-jellybean part is suddenly...out of stock everywhere! No worries, lets show how to find a drop-in replacement so we aren't held up on manufacture.

We've wanted to have something that plugs into a USB A port and provides a QT port for a while. But since we want it to support any and all QT boards, we need more RAM and storage than the SAMD21 can provide. We probably cannot buy any SAMD51's for like a year - but RP2040 is a good option! Lots of RAM and we stuck an 8MB flash on there. The idea is you can attach a QT sensor or whatever on top with some nylon standoffs, maybe it will even auto-detect which sensors are plugged in! We made the boot button a user-button too, thanks to a lil diode friend. #adafruit #raspberrypi #rp2040 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Did you know the SAMD51 has a PCC (parallel capture) peripheral, for reading in camera/video data? that's right, you can directly wire up OV7670/OV2640-like cameras to a SAMD51 and then read out image data into a RAM buffer. We just got support into CircuitPython as well, so we can read a buffer, as seen here, then pipe it back out over SPI to a TFT. Could be great for image recognition, tinyML, DIY cameras, IoT monitoring, etc! The camera almost-perfectly plugs into a Grand Central, you have to cut the two pins for 3V/GND and rewire them, as well as adding I2C pullups.

We had a few PR's go into CircuitPython this week to add digital camera support to platforms with parallel-capture support. We started with SAMD51 and also added RP2040 thanks to some clever PIO work. PaintYourDragon and Jepler teamed up to one-two-punch Arduino and CircuitPy support at once, starting with with classic OV7670 cameras and then moving onto the OV2640's next. This could be great for simple vision/TinyML projects. We also added "Pico-as-hardware-peripheral-for-Blinka" support thanks to u2if https://github.com/adafruit/Adafruit_Blinka/pull/449 which works very nicely and at a price one can't beat! THE GREAT SEARCH - Latching Power Relay for FeatherWing https://www.digikey.com/short/787r7q4h This week's THE GREAT SEARCH comes to us by special request! A kindly person posted up in the forum asking us to make a Latching Power Relay FeatherWing https://forums.adafruit.com/viewtopic.php?f=57&t=178547 We have a latching relay wing already over at https://www.adafruit.com/product/2923 but its not very high current - rated at about 70 Watts, that means at 240VAC you can only switch 0.3A. Compare that to our Power Relay Wing, which can do an impressive 1200 Watts! https://www.adafruit.com/product/3191 Why would we make a latching version, what's single/double winding?

If you are outside the US, double check the time because the US is changing this weekend. Time change in USA 0:00 Getting things going 03:09 hello 06:56 housekeeping 11:25 How do you keep the cats away from the workstation and hot irons? 12:40 how far is circuitpython's implementation of asynchronous I/O scheduler (uasyncio)? 14:44 Is there a time you'd pick the STM32F405 Feather over the SAMD51 feather? They seem similarly capable, but Adafruit seems all-in on the SAMD51 16:10 there was no feather airlift so ordered 1 on digikey which has not even shipped yet Ordered another airlift yesterday from adafruit when it came back in stock so which one will show up first? 18:05 Feather RP2040 flash speed fix 18:34 OSHPark USBmicromod/v1 19:29 Are you using debug-edge in anything?

Make a display for your display! Show off your message to the world. This guide will show how to set up and assemble a Matrix Portal and RGB Matrix display, then make a transparent pocket in your backpack, purse, or messenger bag to show it off. There is also a simple code example that displays your bmp images in slideshow fashion. Use the onboard buttons to switch between folders and play different messages, or pause on your favorite image. Set your bag down and the onboard accelerometer will sense that you're not moving and dim the screen to save battery life. You can also use any of the other Matrix Portal code samples to get you started. Get ready to have fun with all the features the Matrix Portal offers. Plug directly into the back of any HUB-75 compatible display (all the ones we stock will work) from 16x32 up to 64x64! Use the included screws to attach the power cable to the power plugs with a common screwdriver, then power it with any USB C power supply. (For larger projects, power the matrices with a separate 5V power adapter) Then code up your project in CircuitPython or Arduino, our Protomatter matrix library works great on the SAMD51 chipset, knowing that you've got the wiring and level shifting all handled. Here's what you get: ATSAMD51J19 Cortex M4 processor, 512KB flash, 192K of SRAM, with full Arduino or CircuitPython support ESP32 WiFi co-processor with TLS support and SPI interface to the M4, with full Arduino or CircuitPython support USB Type C connector for data and power connectivity I2C STEMMA QT connector for plug-n-play use of any of our STEMMA QT devices or sensors can also be used with any Grove I2C devices using this adapter cable JST 3-pin connector that also has analog input/output, say for adding audio playback to projects LIS3DH accelerometer for digital sand projects or detecting taps/orientation. GPIO breakouts including 4 analog outputs with PWM and SPI support for adding other hardware. Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for address E! Two user interface buttons + one reset button Indicator NeoPixel and red LED Green power indicator LEDs for both 3V and 5V power 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about 'off by one' errors. The Matrix Portal uses an ATMEL (Microchip) ATSAMD51J19, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix. Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don't have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It's the best of both worlds! Comes with one fully-programmed and assembled MatrixPortal, preprogrammed with a rainbow digital sand demo for 32x64 LED matrices. Does not come with an RGB Matrix (use any HUB75 compatible matrix) or a USB type C power supply!

Address E line jumper for use with 64x64 matrices (check your matrix to see which pin is used for address E! Two user interface buttons + one reset button Indicator NeoPixel and red LED Green power indicator LEDs for both 3V and 5V power 2x10 socket connector fits snugly into 2x8 HUB75 ports without worrying about 'off by one' errors. The Matrix Portal uses an ATMEL (Microchip) ATSAMD51J19, and an Espressif ESP32 Wi-Fi coprocessor with TLS/SSL support built-in. The M4 and ESP32 are a great couple - and each bring their own strengths to this board. The SAMD51 M4 has native USB so it can show up like a disk drive, act as a MIDI or HID keyboard/mouse, and of course bootload and debug over a serial port. It also has DACs, ADC, PWM, and tons of GPIO, so it can handle the high speed updating of the RGB matrix. Meanwhile, the ESP32 has secure WiFi capabilities, and plenty of Flash and RAM to buffer sockets. By letting the ESP32 focus on the complex TLS/SSL computation and socket buffering, it frees up the SAMD51 to act as the user interface. You get a great programming experience thanks to the native USB with files available for drag-n-drop, and you don't have to spend a ton of processor time and memory to do SSL encryption/decryption and certificate management. It's the best of both worlds! Comes with one fully-programmed and assembled MatrixPortal, preprogrammed with a rainbow digital sand demo for 32x64 LED matrices. Does not come with an RGB Matrix (use any HUB75 compatible matrix) or a USB type C power supply!

Folks love our PyPortal series, and we're working on making another version, this time with RGB matrix support instead of TFT for huge displays and clocks. The board plugs right in and is powered over USB C. Arduino or CircuitPython supported thanks to the new ProtoMatter library from PaintYourDragon. We tossed one of our favorite sensors, the ST LIS3DH on there as well - so make easy pixel dust projects! This is just our first proto, but looks good so far. #circuitpython #arduino #matrix Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI is a super exciting new Feather board that isn't from us! Alorium's Evo M51 (https://www.digikey.com/product-detail/en/alorium-technology-llc/EVO-M51/2003-EVOM51-ND/11689276) is an FPGA-enhanced embedded module featuring the Microchip SAMD51 32-bit Arm® Cortex®-M4 microcontroller alongside an Intel® MAX 10 FPGA. The Evo M51 board conforms to the Adafruit Feather specification for primary pinout, connectivity, and features - so you can use FeatherWings with this board to add WiFi, OLED or TFT displays, and more! This Feather has a SAMD51 as a main microcontroller processor - we like this chip because it has a fast 120MHz Cortex M4 processor with lots of peripherals like I2C, SPI, UART, ADCs, DACs, lots of DMA, etc. Our Feather M4 features this chip, and it's one of our most popular Feathers (https://www.digikey.com/product-detail/en/adafruit-industries-llc/3857/1528-2648-ND/9553567) Alorium squished it down to a BGA package and used the left over space to wire up an Altera/Intel MAX 10 FPGA (https://www.digikey.com/product-detail/en/intel/10M25DAF256I7G/544-3538-ND/5429545) that can be programmed through the SAMD51 using a command line downloader. By using a SAMD51, which we've supported for a while, this board comes automatically with Arduino and CircuitPython support - that makes programming easy and fast. On the other hand, when you need to get speed, connect to peripherals like cameras or HDMI displays, or perform exceptional calculations very fast...the FPGA is there to lend a hand. You can send messages between the EVO and SAMD51 using I2C or 10-bit parallel bus, so you can take advantage of the easy-to-integrate SAMD51 and the powerful-and-customizable FPGA. You get the best of both worlds! Now, in order to pack so much into a Feather format, a few liberties were taken. For example, the classic 12/16 pin headers go to the SAMD51 and are compatible with FeatherWings. Then the FPGA pins are available on a collection of castellated pads. There's a 'EvoTray" add on board that you can solder the EVO M51 to in order to get breakouts for all the castellations. Features Intel MAX 10 FPGA Microchip SAMD51 32-bit Arm Cortex-M4 microcontroller 512 KB Flash / 192 KB RAM 2 MB external Flash 55 digital I/Os 21 through-hole/castellated 34 additional castellated-only Six analog inputs Two analog outputs STEMMA QT (QWIIC Compatible) Feather footprint 0.9 inches x 2.2 inches Programmable with Arduino Designed for CircuitPython Alorium is also a digital service provider for Intel/Altera FPGAs (https://www.digikey.com/en/design-services-providers/alorium-technology) so you can hire them to help out with your design or get it optimized for manufacturing. Considering a single MAX10M25 is about $85 (https://www.digikey.com/product-detail/en/intel/10M25DAF256I7G/544-3538-ND/5429545) per, getting an EVO M51 (https://www.digikey.com/product-detail/en/alorium-technology-llc/EVO-M51/2003-EVOM51-ND/11689276) fully assembled AND with a co-processor AND Arduino/CircuitPython support AND video tutorials for $97 - its a great deal. If Digi-Key is out of stock, you can backorder it and they'll get you one ASAP - being an NPI there's not a ton of stock right now.

This weekend we worked up making a Stemma QT (qwiic/Grove compatible) breakout for the MLX90640 32x24 camera. We've got it working nicely in Arduino up to about 8 fps (you need a fast processor like the SAMD51 with lots o RAM). Then we went back to our old AMG88xx thermal cam demo and ported it to our EdgeBadge. This camera could be good for low cost thermal imaging and also machine learning! #stemma #machinelearning #adafruit Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

We're testing out a new PR in CircuitPython by JEpler. This one adds native MP3 decoding - no playback chip required! Thanks to the patent expiration, we can now distribute MP3 decoding and its a great way to support compressed audio playback. We can even play 2 mp3's at once. More than that isn't possible yet due to RAM constraints. I'm testing an nRF52840 BLE feather with I2S. We'll also try SAMD51 next. SAMD21 won't be able to do it, due to the RAM requirements. #circuitpython #python #mp3 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Following up on our earlier mass-storage support announcement for TinyUSB, we just added WebUSB support! You can now send and receive data over Chrome (or other WebUSB) browsers with Javascript or whatever else is your favorite web programming language. This can make for really interesting interactions where people don't need any drivers or software to send/receive commands, or perhaps to expose some sort of REPL. The example code is here: https://github.com/hathach/tinyusb/blob/master/examples/device/webusb_serial/src/main.c and here's what the webpage code looks like: https://github.com/adafruit/Adafruit_TinyUSB_Arduino/tree/master/docs/examples/webusb-serial We'll be adding this to our Arduino library shortly, and will follow up when we have the library committed and updated tinyUSB currently supports SAMD21, SAMD51, nRF52840, various LPCs, and STM32F4 - more chips will be supported soon! tinyusb is an open-source (BSD-licensed) USB Host/Device/OTG stack for embedded micro-controllers, especially ARM MCUs. It is designed to be user-friendly in term of configuration and out-of-the-box running experience. #usb #tinyusb #webusb In addition to running without an RTOS, tinyusb is an OS-awared stack that can run across RTOS vendors. For the purpose of eliminating bugs as soon as possible, the stack is developed using Test-Driven Development (TDD) approach.

Tiny Machine Learning on the Edge with TensorFlow Lite Running on SAMD51, we have trained a new model that listens for "up" or "down". You’ve heard of machine learning (ML), but what is it? And do you have to buy specialty hardware to experiment? Nope! If you have some Adafruit hardware, you can build some Tiny ML projects today! We’ve wrappered the TensorFlow Lite micro speech demo to Arduino so you can do basic speech recognition on our SAMD51 boards. In this demo we’ll hook up a microphone to our PyGamer to detect “up” or “down” speech and display some mini videos to play if your voice was detected by TensorFlow Lite, move a bubble wand up or down, controlling a servo, and DC motor, all on a Cortex M4 processor, all battery powered! Code is here – GitHub. https://github.com/adafruit/Adafruit_TFLite_Micro_Speech/tree/updownmodel We used docker for this, we can easily train more models on our local system, and we've uploaded them here on docker hub! https://hub.docker.com/search/?q=ladyada&type=image #machinelearning #tensorflow #tinyml We have a Hackday Hackchat coming up soon, and this is one of the examples we'll be showing off live! https://hackaday.io/project/5373-hack-chat Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe Join our weekly Show & Tell on G+ Hangouts On Air: http://adafru.it/showtell New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

https://blog.adafruit.com/2017/08/01/the-atsamd51-is-here-adafruit-microchipmakes-atsamd51/ Wow some awesome release news from Microchip about a fancy new chip that just dropped. If you know us (and you’re reading this blog so yeah you probably do) you know we just luuuuv the ATSAMD21 – featured in our M0 Feathers, Metro M0 and even the new Gemma M0 we just put in the shop. The ATSAMD21 has always felt to us like the next evolution for fans of the 8-bit AVRs like the ATmega and ATtiny series – with 256 KB of flash, 32 KB of RAM, 48 MHz Cortex M0+ chipset, USB, tons of timers, peripherals, ADC, DAC, up to 6 SPI/I2C/UART devices… using the SAMD21 feels so roomy and comfortable. Adafruit 2132 One of the most fun projects we’ve had over the last year is porting MicroPython to the ATSAMD21 (which we call CircuitPython since the API deviated a bit). Now, MicroPython works just fine on the SAMD21 and you can build many projects quickly, using the built in Python 3 interpretter. And while we absolutely adore it, it’s just a *little bit* sluggish on the ATSAMD21 as its only a Cortex M0 at 48MHz, and doesn’t have any hardware floating point support. And 32KB of RAM is huge for Arduino but CircuitPython can run out of memory if you’re doing a lot. As we started exploring CircuitPython more and more it became clear we could really use an upgrade path. So we asked Microchip “heyyyy so is there like an upgrade to the atsamd21 that’s maybe a cortex m3 or m4, with more RAM and maybe 100 MHz?” and they were all like “maaaybeeee….plz sign this NDA” and we were like “sweet!” and we got a bunch of ATSAMD51 chips and a datasheet! You can check out the no-longer-sekret datasheet here (PDF). The ATSAMD51 is to the ATSAMD21 as it was in turn to the ATMega328. More! Better! Faster! Here are some quick specs: Cortex M4 core running at 120 MHz Hardware DSP and floating point support Up to 1 MByte flash, 192 KB RAM Sizes ranging from 48-QFN to 128-TQFP (the 48 QFN is *nearly* pin compatible with the ATSAMD21 but it isnt 100% drop in compatible) Some neat new peripherals/upgrades: Built in 1.8V buck for lower power uses (needs an external inductor) Dual 1MSPS DAC Dual 1MSPS ADC Parallel capture controller (for camera/video in) Built in crypto engines with AES (256 bit), true RNG, Pubkey controller Ethernet MAC on the SAME5 series QSPI for fast SPI transfers CAN Bus SD/MMC controller “configurable custom logic” – this one is particularly interesting/weird, you get latches and LUT you can link up PDEC – rotary encoder hardware support The speed, and extra space makes it excellent for our next generation of CircuitPython boards, and the price is pretty good too – only about $3 each for the ATSAMD51G19 in reel qty. Considering its the same list price as an ATmega32u4 it’s an easy choice for us! We also like that the pricing is so competitive with other Cortex M4 suppliers, e.g. STM32F405RGT6 is ~$6.50/1K pcs and the similar ATSAMD51J20A is $3.70 (the STM is faster, the SAM has more RAM, it was hard to find a perfect 1:1 comparison) compared to the Kinetis K20 series (famous for being used in the Teensy 3.2) the MK20DX256 has 25% of the Flash size, 25% as much RAM, 60% of the speed, but costs $1-1.25 more. Competition is heating up! Ambahlahdolnogpf Any how, the Atmel ATSAMD51 series looks really awesome to me, and its now public and you can order some chips even from microchip direct. Some chips are in stock now, such as the ATSAMD51N20A-AU, ATSAMD51P19A-AU, others will be shipping in late October. We’ve already started designing a Feather M4 and Metro M4 and we’ve even gotten it going with Arduino core with some tweaks to the current SAMD core. Img 7279 Excited to try out this chip? We don’t have hardware for sale quite yet (and likely won’t until chips are shipping in larger qty in November) but if you have early hardware access for some reason you can check out our forked Arduino SAMD codebase at https://github.com/adafruit/ArduinoCore-samd/tree/samd51 for our latest code – full 120MHz clocking, GPIO, ADC, DAC, I2C/SPI/UART, USB all basically work but there’s a few tweaks and bugfixes still. The BOSSA bootloader working here: https://github.com/adafruit/ArduinoCore-samd/tree/samd51/bootloaders/x1 and the software bootloader tool here: https://github.com/adafruit/BOSSA_x1/tree/arduino We hope to get these all merged into mainline soon, and also a CircuitPython port that can take advantage of the awesome power that can be unleashed! ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com Subscribe to Adafruit on YouTube: http://adafru.it/subscribe Join our weekly Show & Tell on G+ Hangouts On Air: http://adafru.it/showtell Watch our latest project videos: http://adafru.it/latest New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ Music by bartlebeats: http://soundcloud.com/bartlebeats -----------------------------------------
