Adafruit Hallowing M0

Contents

Hardware

Platform :ref:`platform_atmelsam`: 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 Adafruit

Configuration

Please use adafruit_hallowing ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:adafruit_hallowing]
platform = atmelsam
board = adafruit_hallowing

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

[env:adafruit_hallowing]
platform = atmelsam
board = adafruit_hallowing

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Adafruit Hallowing M0 supports the following uploading protocols:

  • atmel-ice
  • blackmagic
  • jlink
  • sam-ba

Default protocol is sam-ba

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:adafruit_hallowing]
platform = atmelsam
board = adafruit_hallowing

upload_protocol = sam-ba

Debugging

:ref:`piodebug` - "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 :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

Adafruit Hallowing 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
:ref:`debugging_tool_atmel-ice`   Yes
:ref:`debugging_tool_blackmagic`    
:ref:`debugging_tool_jlink`    

Frameworks

Name Description
:ref:`framework_arduino` Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
