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 Atmel

Configuration

Please use samd21g18a ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:samd21g18a]
platform = atmelsam
board = samd21g18a

You can override default Atmel ATSAMW25-XPRO settings per build environment using board_*** option, where *** is a JSON object path from board manifest samd21g18a.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:samd21g18a]
platform = atmelsam
board = samd21g18a

; change microcontroller
board_build.mcu = samd21g18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Atmel ATSAMW25-XPRO supports the following uploading protocols:

  • atmel-ice
  • blackmagic
  • cmsis-dap
  • jlink

Default protocol is cmsis-dap

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

[env:samd21g18a]
platform = atmelsam
board = samd21g18a

upload_protocol = cmsis-dap

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`.

Atmel ATSAMW25-XPRO has on-board debug probe and IS READY for debugging. You don't need to use/buy external debug probe.

Compatible Tools On-board Default
:ref:`debugging_tool_atmel-ice`    
:ref:`debugging_tool_blackmagic`    
:ref:`debugging_tool_cmsis-dap` Yes Yes
: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.
