Please use sanguino_atmega644_8m ID for board option in “platformio.ini” (Project Configuration File):

platform = atmelavr
board = sanguino_atmega644_8m

You can override default Sanguino ATmega644 or ATmega644A (8 MHz) settings per build environment using board_*** option, where *** is a JSON object path from board manifest sanguino_atmega644_8m.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = atmelavr
board = sanguino_atmega644_8m

; change microcontroller
board_build.mcu = atmega644

; change MCU frequency
board_build.f_cpu = 8000000L


Debugging - “1-click” solution for debugging with a zero configuration.


You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Sanguino ATmega644 or ATmega644A (8 MHz) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
