Adafruit Feather 32u4¶

Hardware¶

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.

Configuration¶

Please use feather32u4 ID for board option in “platformio.ini” (Project Configuration File):

[env:feather32u4]
platform = atmelavr
board = feather32u4

You can override default Adafruit Feather 32u4 settings per build environment using board_*** option, where *** is a JSON object path from board manifest feather32u4.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:feather32u4]
platform = atmelavr
board = feather32u4

; change microcontroller
board_build.mcu = atmega32u4

; change MCU frequency
board_build.f_cpu = 8000000L

Debugging¶

PIO Unified Debugger currently does not support Adafruit Feather 32u4 board.
