- Example: OLED from the screenshot

The first steps - youtube

Simple LoRa

Platform Installation

Install VS Code + PlatformIO

PlatformIO - Home - Platforms - Advanced Installation

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

Fast Uninstall

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 )

Baremetal INI

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

Arduino INI

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

CUSTOM UPLOADERS

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

Modify the builder / uploader for alternative programmers

Hello everyone,
I have tried various cores for the SAM R34, but I like this very much because it supports PlatformIO, which is great.

A large disadvantage is that it only works with the EDBG chip found on the Xplained Pro board, but not on most custom implementations of the chip.

The question is, what would it take to modify the uploader script to make this work with either Jlink or with a UF2 bootloader? I'm assuming that the compilation wouldn't need to be changed. Can you point me to any resources that guide on how to do this? I'm willing to do this and also have other developers to do this, but we're struggling to find the resources. Thanks.

Support AU_915

Hello, congratulations on the project.

I am working on a project with the frequency AU_915. I would like to contribute the necessary changes for it in Beelan-LoRaWAN, but I confess that I'm a little lost and I didn't understand the relationship between the values of the sequences of defines with the frequencies.

typedef enum {
#if defined(US_915)
    SF10BW125   = 0x00,
    SF9BW125    = 0x01,
    SF8BW125    = 0x02,
    SF7BW125    = 0x03,
    SF8BW500    = 0x04,
    SF12BW500   = 0x08,
    SF11BW500   = 0x09,
    SF10BW500   = 0x0A,
    SF9BW500    = 0x0B,
    SF7BW500    = 0x0D
#elif defined(EU_868)
    SF12BW125   = 0x00,
    SF11BW125   = 0x01,
    SF10BW125   = 0x02,
    SF9BW125    = 0x03,
    SF8BW125    = 0x04,
    SF7BW125    = 0x05,
    SF7BW250    = 0x06
#endif
} dataRates_t;

I'm working with this for changes.

Can you please help me on this most basic point?

WLR089 Xplained Pro, PlatformIO, Arduino, not work

Hi
I have WLR089 Xplained Pro Kit, working with framework arduino, build without errors, upload normally, but not running in WLR089 Xplained Pro, not print serial, not blink LED onboard, nothing works.

But if I make code in Microchip Studio run perfectly.

Does anyone have any solution for this problem?

SAMR34 , Platform IO Hex/bin/elf does not work with custom board

Hello Everyone ,
I am new for Platform IO.
I have SAMR34 Xplained Pro Evaluation Kit and program run perfect with inbuilt EDBG chip with platform IO with Visual code studio.
Now i will load same hex in custom board with j-link EDU from atmel studio then SAMR34 not initiated . But if I make sample code in ATMEL studio then hardware run perfect.
So let me know the solution which i have made in SAMR34 Xplained Pro Evaluation Kit and how can i load that hex file in Custom developed board to make it run.

@pfeerick please check .
