This is fork from https://github.com/Wiz-IO/platform-sam-lora.git

I'm adding here some small functionality, like (all is work in progress):

• uploading using JLink
• add definition for wlr089u0

Version 0.1.2 ( look here, to see if there is something new )

• OS Windows ( for now )
• • Baremetal
• • Arduino ( in process... )
• Board Microchip SAM R34 Xplained Pro
• Framework Source Codes and Examples
• Wiki ( read )

The project is a work in progress and is very beta version - there may be bugs

• CMSIS
• ASF ( v 3.47.0.96 )
• • Example: LED Blink

• Arduino core
• GPIO, ADC, Serial, I2C, SPI, RF
• LoRa & LoraWAN
• Variant: Microchip SAM R34 Xplained Pro
• • Example: Hello World
• • Example: OLED from the screenshot

The first steps - youtube

Simple LoRa

Install VS Code + PlatformIO

PlatformIO - Home - Platforms - Advanced Installation

Paste link: https://github.com/Wiz-IO/platform-sam-lora

Goto C:\Users\USER_NAME\.platformio\platforms and delete:

• folder sam-lora ( builders )
• folder framework-sam-lora ( sources )
• folder tool-sam-lora ( uploader )
• folder toolchain-gccarmnoneeabi (compiler )

[env:samr34xpro]
platform = sam-lora
board = samr34xpro
framework = baremetal
monitor_port = COMx     
monitor_speed = 115200  

[env:samr34xpro]
platform = sam-lora
board = samr34xpro
framework = arduino
monitor_port = COMx     
monitor_speed = 115200  

The Platform use Microchip SAM R34 Xplained Pro with onboard EDBG uploader

I don't have a J-LINK, Atmel ICE, stand alone modules and/or custom bootloaders to add more uploaders

The code has a custom experimental "bootload" uploader and you can use it as an entry point for your experimental uploaders

https://github.com/Wiz-IO/platform-sam-lora/blob/master/builder/frameworks/SAMR_FU.py

The main upload entry function is:

dev_upload(target, source, env)

https://github.com/Wiz-IO/platform-sam-lora/blob/master/builder/frameworks/arduino-samr34.py#L14

There are conditions for distinguishing the tool used - edit and test...

Create new board, Copy/Paste/Rename and edit boards/samr34xpro.json as experimental board

• Baremetal Uploaders ( now works with atbackend/atprogram )
• Baremetal ASF/CMSIS
• Arduino Bootloader
• Arduino Core
• Arduino Libraries
• Examples

• Ivan Kravets ( PlatformIO )
• Miguel Romani ( TheThings )
• Comet Electronics
