this may be helpful for folks using the latest attiny and atmega chips that are programmed with "synch uart" UPDI rather than "SPI" AVR-ISP: we've updated our self-contained/standalone programming library to add UPDI support! the library is here, https://github.com/adafruit/Adafruit_AVRProg example here: https://github.com/adafruit/Adafruit_AVRProg/tree/master/examples/attiny817_updiprog we can erase-program-verify an 8KB flash chip in 2 seconds, super fast. great for loading firmware in production. thanks to bradanlane's portaprog for much of the updi support implementation: https://gitlab.com/bradanlane/portaprog/-/blob/master/src/avrupdi.cpp #adafruit #arduino #UPDI Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------
