Projects
Atmel's ATtiny816 is the perfect microcontroller for an upcoming project that requires components to be as small as possible. The introduction unit for microprocessors and digital systems CAB202 used a ATtiny1616 in its QUTy board. I had already learnt a decent amount to be able to understand what is going under the hood. With a QFN packaged chip, having a breakout board was essential to tinker with it.
The USB-C only has the function of delivering power as the serial communcation for the ATtiny is UPDI (Unified Program and Debug Interface). Needing only three wires, I used exposed pads in order that can be programmed with pogo pins. Killing two birds with one stone in this project, I also wanted to test out the WS2818C-2020 RGB LEGS for an upcoming project, otherwise a single LED would be suffice as a visual indicator.
Thankfully I still had my QUTy board from CAB202, otherwise it would have been a couple of days waiting for a UPDI programmer. I was able to Frankenstein the USB to UART chip to a pogo pin stick I made.
