Arduino M0

Hardware

Platform Atmel SAM: Atmel | SMART offers Flash- based ARM products based on the ARM Cortex-M0+, Cortex-M3 and Cortex-M4 architectures, ranging from 8KB to 2MB of Flash including a rich peripheral and feature mix.

Microcontroller	SAMD21G18A
Frequency	48MHz
Flash	256KB
RAM	32KB
Vendor	Arduino

Configuration

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

[env:mzeroUSB]
platform = atmelsam
board = mzeroUSB

You can override default Arduino M0 settings per build environment using board_*** option, where *** is a JSON object path from board manifest mzeroUSB.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:mzeroUSB]
platform = atmelsam
board = mzeroUSB

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Arduino M0 supports the following uploading protocols:

• atmel-ice

• blackmagic

• jlink

• stk500v2

Default protocol is stk500v2

You can change upload protocol using upload_protocol option:

[env:mzeroUSB]
platform = atmelsam
board = mzeroUSB

upload_protocol = stk500v2

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).

Arduino M0 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.

Compatible Tools	On-board	Default
Atmel-ICE		Yes
Black Magic Probe
J-LINK

Frameworks
