Pololu A-Star 32U4¶

Hardware¶

Platform Atmel AVR: Atmel AVR 8-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 industry’s most code-efficient architecture for C and assembly programming

Configuration¶

Please use a-star32U4 ID for board option in “platformio.ini” (Project Configuration File):

[env:a-star32U4]
platform = atmelavr
board = a-star32U4

You can override default Pololu A-Star 32U4 settings per build environment using board_*** option, where *** is a JSON object path from board manifest a-star32U4.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:a-star32U4]
platform = atmelavr
board = a-star32U4

; change microcontroller
board_build.mcu = atmega32u4

; change MCU frequency
board_build.f_cpu = 16000000L

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

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

Pololu A-Star 32U4 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
