Configuration

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

[env:seeed_xiao]
platform = atmelsam
board = seeed_xiao

You can override default Seeeduino XIAO settings per build environment using board_*** option, where *** is a JSON object path from board manifest seeed_xiao.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:seeed_xiao]
platform = atmelsam
board = seeed_xiao

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Seeeduino XIAO supports the next uploading protocols:

  • atmel-ice

  • blackmagic

  • jlink

  • sam-ba

Default protocol is sam-ba

You can change upload protocol using upload_protocol option:

[env:seeed_xiao]
platform = atmelsam
board = seeed_xiao

upload_protocol = sam-ba

Debugging

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

Warning

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).

Seeeduino XIAO does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
