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 OP ,
@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 OP ,
@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 OP ,
@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 OP ,
@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 OP ,
@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 OP ,
@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.

Keep your Pico toes Toasty with a DVI Sock

the Raspberry Pi RP2040 has a fun trick up it's sleeve, er, pants! it can bitbang DVI video output from a series of pins using PIO as long as its overclocked enough and you have the PIO peripherals available. we already designed a DVI PiCowbell (https://www.adafruit.com/product/5745), but we rather like the DVI sock design originating from wren6991 (https://github.com/Wren6991/Pico-DVI-Sock)

adafruit OP ,
@adafruit@mastodon.cloud avatar

it's designed to slip on to the 'foot' of a Pico or PicoW and there's a few times where i've thought "oh man I wish I had a DVI sock to test this-or-that" so here's our spin on it, we kept the sockish-PCB, the full-size DVI port, mounting holes, and passives. we added a couple more breakout holes for CEC, Util and HotPlugDetect. this should make our video toaster, er, toaster video projects ez-breezy

Coming soon - Pixel Trinkey!

We were taking a look at the new Windows 11 HID Dynamic Lighting protocol (https://learn.microsoft.com/en-us/windows-hardware/design/component-guidelines/dynamic-lighting-devices) and i thought this would be a good excuse to design a small NeoPixel or DotStar driver board. like many of our other Trinkeys (https://www.adafruit.com/search?q=Trinkey) it is running a SAM21E18, which is a small chip, but the 32KB of SRAM can drive nearly 10,000 pixels! we put a 5V level shifter on a SPI peripheral so they could be used as data/clock or,

adafruit OP ,
@adafruit@mastodon.cloud avatar

if you want, two NeoPixel strands. this isn't a super-fancy driver: it isn't NeoPXL8 (https://www.adafruit.com/search?q=neopxl8) where you get dithering and DMA, but it's probably just fine for the vast amount of lighting projects.
