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.
[env:samr21_xpro] platform = atmelsam board = samr21_xpro
You can override default Atmel ATSAMR21-XPRO settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest samr21_xpro.json. For example,
[env:samr21_xpro] platform = atmelsam board = samr21_xpro ; change microcontroller board_build.mcu = samr21g18a ; change MCU frequency board_build.f_cpu = 48000000L
Atmel ATSAMR21-XPRO supports the next uploading protocols:
Default protocol is
You can change upload protocol using upload_protocol option:
[env:samr21_xpro] platform = atmelsam board = samr21_xpro upload_protocol = cmsis-dap
PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.
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.
Atmel ATSAMR21-XPRO has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

|Mbed||The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.|
|Zephyr||The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.|
