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:itsybitsy32u4_3V] platform = atmelavr board = itsybitsy32u4_3V
You can override default Adafruit ItsyBitsy 3V/8MHz settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest itsybitsy32u4_3V.json. For example,
[env:itsybitsy32u4_3V] platform = atmelavr board = itsybitsy32u4_3V ; change microcontroller board_build.mcu = atmega32u4 ; change MCU frequency board_build.f_cpu = 8000000L
