Pinout

ATtiny814_DevBoard_pinout.png

Preparing Arduino IDE

  • Install megaTinyCore
  • Open the Arduino IDE
  • Go to "Tools" -> "Board" -> "megaTinyCore" and select your chip
  • Go to "Tools" and set the desired board options
  • Go to "Tools" -> "Programmer" and select "jtag2updi(megaTinyCore)"
  • Connect the UPDI programmer to the UPDI header on the development board. You can find such programmers in my projects or you can use an Arduino Uno as a UPDI programmer.
  • Go to "Tools" -> "Burn Bootloader"
  • Now you can upload your sketch
