Full tutorial: https://learn.adafruit.com/scannable-links-with-nfc/overview Are you a connector? Are you always handing out business cards, sending people to your Etsy store, your blog, or your product? Do you meet people at festivals or conventions and need an easy way to connect, and stay connected? This tutorial is for you. With an NFC tag and a few clicks in a smartphone app, you can create a necklace, necktie, hat or costume piece that not only makes you look sharp, but also helps you connect with your people. Simply tap your necklace to a smart phone with NFC technology (which is most of them, these days) and your contact info will appear on their screen like magic. Or, set up a Venmo link on your NFC tag to make a tap-to-pay sign that's even easier for your customers to use than a QR code. NFC tags offer so many possibilities.

A few weeks ago, we covered the 2x5 0.05" pitch SWD sockets https://blog.adafruit.com/2023/08/14/the-great-search-2x5-0-05-jtag-swd-connector-and-cable-thegreatsearch-digikey-adafruit-digikey-adafruit/ that we have on many of our dev boards. Those connectors are standard issues for programming Arm Cortex chips with SWD or other devices with JTAG. However, sometimes you don't need or want the bulk of a chonky IDC connector - and only some customers will need to field reprogram or debug. But just having pogo pads is more accessible to connect to if you have the specific jig. We'll cover two solutions for 'press fit' programming: Tag Connect standard https://www.tag-connect.com/ and another exciting option we spotted on Twitter, now called X, from arturo182 and abhinav_937 https://twitter.com/arturo182/status/1701760589419208995 , is using a SKEDD REDFIT cable. https://www.digikey.com/short/t1hhf3qj See the chosen part on DigiKey https://www.digikey.com/short/327pnnbw Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #deskofladyada #thegreatsearch #digikey #hardwarehacking #prototyping #usbhost #tinyusb #featherwing #chatgpt4 #debouncing #swdsockets #tagconnect #skeddredfit

Many microcontrollers have ADCs these days for reading analog/resistive sensors like potentiometers, thermistors, LDR light sensors, etc., but sometimes you need MOAR! or maybe you're using a single board computer like a Raspberry Pi that has no ADCs at all...the ADS7830 is an affordable 8-channel ADC with I2C interface, so it's easy to include with any platform. There are 2 address pins, so you could have 4 x 8 = 32 total ADC channels with chain-able Stemma QT cables. You can get up to 70 Ksamples per second, but only 8-bits of resolution, so it's suitable for rough sensor measurements. This would be a great way to add a ton of potentiometers to a build, especially if it contained a Raspberry Pi, prototype coming soon! https://www.digikey.com/short/5t1w37hb Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #electronics #pcb #opensource #opensourcehardware #pcboftheday #analoginputs #8channeladc #microcontrollers #raspberrypi #ads7830 #i2cinterface #sensorreadings #stemmqt #70ksamples #potentiometerbuild

Our last few experiments with playing video+audio on the ESP32-S3 involved converting an MP4 to MJpeg + MP3, where MJpeg is just a bunch of jpegs glued together in a file, and MP3 is what you expect. This works, but we maxed out at 10 or 12 fps on a 480x480 display. You must manage two files, and the FPS must be hardcoded. With this demo https://github.com/moononournation/aviPlayer we are using avi files with Cinepak https://en.wikipedia.org/wiki/Cinepak and MP3 encoding - a big throwback to when we played quicktime clips on our Centris 650. The decoding speed is much better, and 30 FPS is easily handled, so the tearing is not as visible. The decoder keeps up with the SD card file, so you can use long files. This makes the board a good option for props and projects where you want to play ~480p video clips with near-instant startup and want to avoid the complexity of running Linux on a Raspberry Pi + monitor + audio amp. The only downside right now is the ffmpeg cinepak encoder is reaaaaallly slooooow.

This week on The Great Search, this xeet posting caught our eye https://twitter.com/collingall/status/1699140384608133233. It's a massive box of lovely RCA connectors! RCA connectors are ancient but still very popular for analog audio plus NTSC/PAL composite video use. You can get them individually or pre-molded in a row. Common configurations are single-mono audio, stereo audio, or stereo audio + composite, but 'component' analog video (https://en.wikipedia.org/wiki/Component_video) is not uncommon either. We'll look at RCA connectors and try to find a triple-set with Red, Green, and Blue color-coded plastic.

This Mini TV demo https://github.com/moononournation/MiniTV by moononournation is perfectly themed for Star Trek day, playing the TOS and STNG intros at 480x480 12fps MJpeg and 22KHz I2S MP3 audio. We'll try Cinepak next, but this was an easy first start, and it looks and sounds great. There's a little tearing effect due to the low frame rate and the display being single, not double-buffered, but considering this is a $4 microcontroller module running Arduino, it's very impressive! This may be the first time we've seen reasonable size-and-quality video+audio playback! This was our last 'test' for the ESP32-S3 TFT Experimenter board. All functionality has been tested, and it's ready to go out for manufacture - only one blue-wire fix is needed to change the default I2C address of the GPIO expander :) Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- @EspressifSystems @StarTrekOfficial @Arduino #StarTrekDay #espressif #esp32 #adafruit #espfriends #ESP32S3 #arduino #startrekfan #minitv #techdemo #audiovisual #innovation #diyprojects #microcontroller #videoplayback #trekkie #engineeringmagic

This week's EYE ON NPI is a treasure, and will measure pressure with pleasure...it's the Amphenol All Sensors' ELVH Series Digital and Analog Pressure Sensors (https://www.digikey.com/en/product-highlight/a/all-sensors/elvh-series-digital-and-analog-pressure-sensors). A family of temperature and pressure sensors with a ton of different configurations so you can definitely fit it into your design no matter what interface or usage range. These sensors integrate a process improvement to the sensing element: the CoBeam2 series is a MEMS etched piezo-resistive 'strain gauge diaphragm'. This li'l chunk of silicon creates a Wheatstone bridge where the pressure against the die makes microscopically small changes to the resistances that can be measured on the differential output. That's not surprising: pretty much all absolute or differential pressure sensors come as 4-element Wheatstone bridge configuration (https://www.digikey.com/short/jp83d457) - and these require extra analog circuitry to handle and amplify the small voltage change readings, or a high precision ADC - we've covered 24-bit ADCs for reading bridge sensors on earlier EYE ON NPIs (https://www.youtube.com/watch?v=7Xkr7OjHQfU). With the ELVH family of sensors, you can get cleaned-up ratiometric analog output, or ready-to-integrate I2C or SPI - so you can pair these even with fully-digital microcontrollers or microcomputers that have no analog inputs. Plus, since its digitized already, you also get bonus status bits and temperature reads. This full family of pressure and temperature sensors comes in a dizzying set of possible packages and configurations, from SMT J-Lead to through hole DIP or SIP. There's also both absolute and differential input-ports, and barbed, needle or flat ports that can connect with common tubing to measure pressure inside a cavity or ambiently. Of course, temperature will always be an 'on-chip' ambient measurement. For any sort of industrial or medical purpose, you can pick the pressure range from as low as 1inH2O (0.0025 bar) to +10 bar. Finally, both I2C and SPI are available for digital read-out, or analog if you want to maintain compatibility with older sensors. If you're designing a product that requires measuring air or gas pressure, and you want to skip the whole analog-front-end development part to get to market fast - check out these Amphenol All Sensors' ELVH Series (https://www.digikey.com/en/product-highlight/a/all-sensors/elvh-series-digital-and-analog-pressure-sensors) - DigiKey stocks almost 200 different varieties of the ELVH sensor family (https://www.digikey.com/short/m4vr4wr5) which means that even if your requirements change during R&D, you will be able to get perfect pressure readings. Since they are in stock for immediate shipment, you can order tonight and get any flavor you like by tomorrow morning.

If you're a fan of our INA219 DC current/voltage monitor breakout https://www.adafruit.com/product/904 , this new prototype will make your heart grow thrice daily. The INA3221 https://www.digikey.com/en/products/detail/texas-instruments/INA3221AIRGVR/3588826 is a triple-channel voltage and current monitor for high side monitoring. We designed this breakout but were puttering around trying to find a solid chunk of time to write a driver for it - but with our new ChatGPT robot friend, we were able to spend 15-30 minutes here and there throughout the day to get the driver written, here's the log so far https://chat.openai.com/share/1b886196-3de2-4ac4-a719-7c12f70d88b8 There's a little cleanup and of course more testing to do but so far the code it generated is working nicely!

The driver that we used ChatGPT 4 to write is for the VCNL4020 https://www.digikey.com/short/dpz897jj, an 'all in one' IR proximity sensor. These sensors work by bouncing bright IR light off a surface and measuring how much returns. The IR light is modulated and relatively resistant to ambient light interaction. One of the first sensors we ever used was the Sharp GP2Y https://www.adafruit.com/product/164. It is famous for its ease of use in the days when cheap microcontrollers provided 5V power and an analog signal that roughly maps with distance is emitted. While you can still get analog distance sensors https://www.digikey.com/short/d21wnm5c, I2C interfacing lets you get data quickly and adjust for lower power usage. Let's look at some digital IR proximity sensors and other distance sensors (and the differences between them!)

This light and proximity sensor using the VCNL4020 https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4020-GS08/2813348 was designed a few months ago, but we were dragging our feet on writing the library code as its kind of a tedious process. Now, with our new BFF ChatGPT4, we can crank through a library with minimal typing. Of course, we check each function and #define as it is written - sometimes typos and misunderstandings come through. But overall, it's a much faster and easier process. We wrote a full-coverage library and example sketches in only a couple hours. Here's the chat log https://chat.openai.com/share/f44dc335-7555-4758-b2f9-487f9409d556 - The output still needs to be cleaned up a tad, but you can see the library here while we hack on getting it to pass CI https://github.com/adafruit/Adafruit_VCNL4020 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #openai #chatgpt #arduino #adafruit #opensource #opensourcehardware #ai #VCNL4020 #proximity #sensor #coding #hardwaretesting #librarydevelopment #prototyping #automation #developerlife #electronics #embeddedsystems #breakoutboard #innovation

We wrote a driver this week for the HUSB238 USB PD sink chip https://blog.adafruit.com/2022/05/04/plug-n-play-usb-type-c-dummy-pd/ - this IC is neat in that you can either use jumpers (really, resistor selection) to set the desired PD voltage and current ooooor you can use I2C for dynamic querying and setting. we have a wall adapter that can provide almost-all-PD voltages: 5/9/12/15/20 only 18 is skipped. The HUSB plugs into the USB C cable and, over the CC lines, will negotiate the PD request and commands. For example, we can ask what voltages are available and then iterate over the options here: a multimeter displays the output voltage to prove it works! This can be a handy chip for projects where you need a lot more than 5V @ 2A power: this adapter can give up to 20V at 5A - yes 100W over USB C - and you could buck that down to get a toooon of current at 5V or 12V if that's needed. Arduino library and example code is here https://github.com/adafruit/Adafruit_HUSB238 . This is also one of the first shipping boards using an OpenAI ChatGPT assisted library https://chat.openai.com/share/d05c963d-b610-4eef-ad98-05656a33e118 https://chat.openai.com/share/a276ce74-f810-4dba-a324-e9fd1545085f Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #arduino #HUSB238 #opensource #opensourcehardware #USBPD #usbc #powerdelivery #techinnovation #smartchip #electronics #projectpower #voltagecontrol #driverupdate #usbchip #hardwaredevelopment #openai #chatgpt

One of the big tasks that Ladyada still has to spend a lot of time on is writing Arduino libraries for all our devices and sensors, particularly all the I2C & SPI chips out there! These ICs use register maps and sub-byte addressing to set dozens of configurable knobs and switches, and a good driver lets folks set and get all of the noodly bits. However, there is yet to be a standard format to get that configuration map. Instead, you have to pore over datasheets with long lists of binary tables and bit insets to figure out how to convert that into C or Python code. It is tough. Only a few folks can write an excellent comprehensive library.... but Ladyada can & has! In fact, there are hundreds of Arduino libraries on Adafruit's GitHub https://github.com/orgs/adafruit/repositories, all in the Ladyada 'style,' using Adafruit_BusIO for I2C / SPI register addressing https://github.com/adafruit/Adafruit_BusIO/ and since ChatGPT 4 was trained on all of it, we can ask it to become a mini-Ladyada to write new drivers. With a PDF parsing plugin, we can even upload the chip's datasheet to extract register names, values, create enum tables, and text for doxygen comments. Here's the chatGPT log for the video https://chat.openai.com/c/f740eb57-17a6-41e3-ae0a-12da959a1f4c - and here's a previous one that is more 'complete' https://chat.openai.com/share/f44dc335-7555-4758-b2f9-487f9409d556. The amount of time it takes for ChatGPT to write a driver is about the same as it would take Ladyada, and you definitely need to be eagle-eyed to redirect the AI if it starts making mistakes... but it can be done even when Ladyada is tired after a full day of baby-care, or at the same time as pumping https://www.youtube.com/watch?v=EpbH-sXRNps - plus there's a lot less continuous typing/mousing so her wrists don't ache the next day! Do you use ChatGPT for electrical engineering or coding work? Any suggestions on how to make this even better? This is only our 3rd day using this tool, so we're getting started with how to integrate it into our workflow.

Now that we have somewhat-kinda-sorta working support for RGB TFT displays on the ESP32-S3 - shout out to Jepler, who is doing the hard work over in this PR https://github.com/adafruit/circuitpython/pull/8351 - its time to test it with wifi too! That's right, the S3 can do wifi and these big displays at once, and CircuitPython is a beautiful framework for it since its so fast to iterate. This code snippet is based on PaintYourDragon's moon clock code here https://learn.adafruit.com/moon-phase-clock-for-adafruit-matrixportal but pared down for testing. We get the geolocation from IP, then look up the moon phase. Currently we just hardcoded it to display today's phase, but the next step is generating ~28 different phase images, and we'll display the one for the current evening as the API informs us.

CircuitPythonista Jepler has been hard at work getting full framebuffer support for RGB TFT displays into CircuitPython https://github.com/adafruit/circuitpython/pull/8351 - which means we can see the REPL on a display as large as this 720x720 4" square TFT! as we type into USB the text mirrors immediately, and we can also use any displayio https://learn.adafruit.com/circuitpython-display-support-using-displayio function or library.

This week's EYE ON NPI will "Speak Friend and Enter" your wireless connectivity toolbox, it's TE's LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/lembas-lte-gnss-usb-modem) an easy-to-use full powered cellular and GPS modem designed specifically to be used with single-board Linux computers (SBCs) to add networking and location tracking with a simple plug-and-play USB connection. We bought one and popped it open - not recommended because it will void your warranty - and found inside is a Quectel EC25-AFXD module (https://www.digikey.com/en/products/detail/quectel/EC25AFXGA-128-SGAS/13278280) - an LTE Cat 4 data-only module with high speed uplink and downlink when LTE is available, and GSM/GPRS backward-compatibility for remote areas. Quectel EC25 is a series of LTE Cat 4 modules optimized specially for M2M and IoT applications. Adopting the 3GPP Rel-11 LTE technology, it delivers maximum data rates up to 150 Mbps downlink and 50 Mbps uplink. Designed in the compact and in a unified form factor, the EC25 series is compatible with Quectel multi-mode LTE Standard EC21 series/EC20-CE/EG25-G/EG21-G modules and UMTS/HSPA+ UC200A-GL module, which allows for flexible migration among them in design and manufacturing... backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage. EC25 series supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BDS, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning. The LEMBAS has a lot of little details that shows the design team focused on a high quality build and removing any obstacles to use. For example, instead of a 'USB stick' style modem that blocks all of the USB ports on your raspi, the modem uses any USB Type C cable - this also allows the user to place the LEMBAS wherever the antenna will get best reception. When we opened it up, we noticed that the board was conformal coated (https://www.digikey.com/en/products/filter/coating-grease-repair/642), so it will handle being exposed to humid air, although please note it's not rated for outdoor use. The SIM card is pre-installed but can be removed / replaced easily if a particular data service is desired. We also thought the status LEDs that appear as part of the TE logo showed a cute designer touch. One handy design decision that makes the LEMBAS easy to get started with: inside is a 2-port USB hub (https://www.digikey.com/en/products/detail/texas-instruments/TUSB4020BIPHP/5724124) so that, when plugged into USB, it shows up as both the modem interface and a small USB storage key. On that storage are all the files you need to run to install the modem interface on an Arm32 or Arm64 computer like the Raspberry Pi. This definitely solves the "to get on the internet I have to install my wireless drivers but I can't get onto the internet because I haven't installed my wireless drivers" problem. And of course, there's a GNSS inside as well, which makes this perfect for asset tracking or geo-locating projects where you need to know where the code is running from. It's ready to go in an instant and with native Linux support for cellular modems, you don't need to do any AT command noodling - use Python or node.js or whatever language your application is and open secure sockets like normal. If you've got a hankerin' for a piece of Elvish-quality technology that will let you communicate anywhere in the world, even on the top of Mt. Doom, you can pick up a TE LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/short/4172bndv) from DigiKey today and it will ship to you as fast as a gigantic eagle so that you can get started tomorrow morning... right after second breakfast!

IPS TFT displays, and 3.5" floppy drives are like surf-n-turf: at no point did a lobster or cow ever meet each other before being plated at a restaurant, yet they are a tasty combination. We are testing a 4" 720x720 square display with a capacitive touch overlay using our Espressif ESP32-S3 TFT experimenter board. At this resolution, we're definitely pushing the capabilities of our lil Tensilica chip, but it's still an excellent way for us to verify the displays are good before we maybe get them set up on the ICN6211 DSI-to-RGB converter https://youtu.be/jJQQbaxTS28 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- @EspressifSystems #hackers #floppy #floppydisk #diskimage #adafruit #arduino #electronics #opensource #opensourcehardware #espressif #esp32 #espfriends #display #tftdisplay #innovation #techcombo #diyprojects #tensilicachip #pixelmagic #retrotech #gadgetgeek #touchscreen #moddingmagic

We got the round displays working on our ESP32-S3 RGB display driver, so now we're moving on to the bar displays! These are longer than most rectangular displays and are kind of fun if you want to, say, animate a sushi conveyor belt. We're having a bit of flakiness from this one; the hsync and vsync or pclk settings given to us by the factory aren't quite right because you can see the display shift up and down. There's also a flickering effect: from us using single-buffer display mode where we draw the next frame on top of the current one while it is displayed. The way to get buttery-smooth animations here is to double-buffer at a cost of twice the RAM requirement.

Much like our 4.6" display we just tested, this 3.7" display is a looooong and thin boi. It has 960x240 pixels and a 40-pin RGB TTL interface. We're testing it out by drawing a cute sushi animation on it - and we see that while we still get the 'not double buffering' flicker, we don't see the image shift around like the 4.6" - which means maybe we've got more-stable values for the hsync/vsync.
