Arduino Due (USB Native Port)

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.

Microcontroller AT91SAM3X8E
Frequency 84MHz
Flash 512KB
RAM 96KB
Vendor Arduino

Configuration

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

[env:dueUSB]
platform = atmelsam
board = dueUSB

You can override default Arduino Due (USB Native Port) settings per build environment using board_*** option, where *** is a JSON object path from board manifest dueUSB.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:dueUSB]
platform = atmelsam
board = dueUSB

; change microcontroller
board_build.mcu = at91sam3x8e

; change MCU frequency
board_build.f_cpu = 84000000L

Uploading

Arduino Due (USB Native Port) supports the next uploading protocols:

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

Default protocol is sam-ba

You can change upload protocol using upload_protocol option:

[env:dueUSB]
platform = atmelsam
board = dueUSB

upload_protocol = sam-ba

Debugging

PIO Unified Debugger - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Arduino Due (USB Native Port) 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
Atmel-ICE   Yes
Black Magic Probe    
J-LINK    
ST-LINK
