SODAQ SARA¶

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.

Configuration¶

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

[env:sodaq_sara]
platform = atmelsam
board = sodaq_sara

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

[env:sodaq_sara]
platform = atmelsam
board = sodaq_sara

; change microcontroller
board_build.mcu = samd21j18a

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading¶

SODAQ SARA supports the next uploading protocols:

• atmel-ice

• blackmagic

• jlink

• sam-ba

Default protocol is sam-ba

You can change upload protocol using upload_protocol option:

[env:sodaq_sara]
platform = atmelsam
board = sodaq_sara

upload_protocol = sam-ba

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

SODAQ SARA 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.
