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:samd21_xpro] platform = atmelsam board = samd21_xpro
You can override default Atmel SAMD21-XPRO settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest samd21_xpro.json. For example,
[env:samd21_xpro] platform = atmelsam board = samd21_xpro ; change microcontroller board_build.mcu = samd21j18a ; change MCU frequency board_build.f_cpu = 48000000L
Atmel SAMD21-XPRO supports the next uploading protocols:
Default protocol is
You can change upload protocol using upload_protocol option:
[env:samd21_xpro] platform = atmelsam board = samd21_xpro upload_protocol = cmsis-dap
Debugging - “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 SAMD21-XPRO has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
