Platform Atmel AVR: Atmel AVR 8- and 32-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Optimized to speed time to market-and easily adapt to new ones-they are based on the industrys most code-efficient architecture for C and assembly programming.
[env:ATmega644P] platform = atmelavr board = ATmega644P
You can override default ATmega644P/PA settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest ATmega644P.json. For example,
[env:ATmega644P] platform = atmelavr board = ATmega644P ; change microcontroller board_build.mcu = atmega644p ; change MCU frequency board_build.f_cpu = 16000000L
