Desk of Ladyada - Load Cells & HID Keyboards https://youtu.be/HoPInrsFSDI

Waiting for prototype PCBs, we started new projects. We're designing an HX711 breakout board with SPI for multiple sensors and updating the NAU7802. Also exploring CH9328 for HID keyboards via UART. Looking for compact 1.27mm pitch SMT DIP switches on DigiKey for a new design.

Preview - Stemma plug-n-play adapter for DS18B20's

one of the perks of working at adafruit is you get to request hardware - and you'll probably get fast turnaround! one of our adafruit.io dev's requested "an easy way to chain DS18B20 sensors for testing with adafruit.io's wippersnapper service" (https://learn.adafruit.com/using-ds18b20-temperature-sensor-with-wippersnapper) at 11:54am and after a few back-and-forth's we spun up this prototype idea.

you can use JST 3-pin cables (https://www.adafruit.com/product/4336) to 'chain' the adapters. then screw terminals mean you can easily connect DS18B20's in TO-92 (https://www.adafruit.com/product/374) or cable style (https://www.adafruit.com/product/381). there's a 4.7K signal pullup on board that can be disabled by cutting a trace, and a buffered signal LED that will let you know when there's data transmission on the 1-Wire line. prototype PCBs were ordered at 12:31pm, less than an hour from idea to booking!

CH552 QT Py Tester is Ready to Rock

We designed this CH552-based QT Py to play around with this '40 cent' USB-capable chip, and it's been super fun! now the hardware is complete and assembled, its time to test it so it can go into the shop. we wrote a test sketch in Arduino (https://github.com/DeqingSun/ch55xduino) board support package to verify the GPIO are working right on the pogo bed.

@adafruit the test output goes to the USB serial port which is then read by a python script. to program it, we use the raspberry pi and ch552tool (https://github.com/MarsTechHAN/ch552tool), we can enumerate, test and program the final neopixel swirl in about 10 seconds.

Preview! More RISC-y endeavors with CH32V203

@adafruit@mastodon.cloud avatar

we had so much fun with our CH552 QT Py design, (https://blog.adafruit.com/2024/04/15/desk-of-ladyada-the-8051-throwback-episode-ch552-deskofladyada-adafruit-adafruit/) we thought maybe we could make a board with it's 'big sister' the "35 cent" RISC-V based CH32V203.

adafruit,
@adafruit@mastodon.cloud avatar

(https://www.wch-ic.com/products/CH32V203.html). this is the CH32V203G6 which is a QFN-28 version of the chip, with 32KB of Flash and 10KB of SRAM. we would have preferred to use the F8 QFN-20 with double the flash and RAM, but this variant part was easier to buy. we wanted to get going quickly so the board layout is 4-layer.

adafruit,
@adafruit@mastodon.cloud avatar

we sorta feel like having a 4-layer board, and the attendant cost, sorta is at odds with such a low cost chip, but we think that converting it to 2-layer would take a couple more hours, and we're getting a bit tired tonight. with UART, SPI, I2C and USB bootloader, we think this is a cute qt for checking out this fun chip.

TRRS Trinkey makes AT projects EZ

ATMakers emailed and asked if we'd make a Trinkey (https://www.adafruit.com/search?q=trinkey) with a TRRS jack (https://www.adafruit.com/product/5764) on the end, for making customizable HID devices that use simple 3.5mm audio jack connectors. ideally something that will make AT - Accessibility Technology - projects EZ to build and maintain.

adafruit,
@adafruit@mastodon.cloud avatar

here's our take on it, what's interesting is each pin of the jack - including the two switches for tip and ring1 - connect to GPIO / analog inputs on the SAMD21. there's no pre-defined VCC or GND because different switch and joystick makers have different configurations and we might want to change around what pins are power, ground, pullups, etc!

adafruit,
@adafruit@mastodon.cloud avatar

this board will be great for use with CircuitPython to make any sort of AT switch or potentiometer interface super fast, to demo it we've written up a quick CPy sketch that will listen for two switches, and when they're pressed, blink the NeoPixel and emit keypresses as if its a keyboard.

adafruit,
@adafruit@mastodon.cloud avatar

code is in the PR for this board (https://github.com/adafruit/circuitpython/pull/9190#issuecomment-2067764251) since we have great HID support it could also be a mouse or joystick device and it will work with any computer/tablet/console with a USB port.
