CH552 QT Py Tester is Ready to Rock

Adafruit Industries

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. 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.
