pico-lora

LoRa communication library for Raspberry Pi RP2040 Microcontroller.

This library is written for RP2040 C++ SDK.

The main changes from the repository credited are a fixed available function (for our setup, may not work for you), and a TX/RX enable setup like Arduino's RadioLib. These changes were required for our modules (RP2040 MicroMod with the MicroMod LoRa 1W function).

Supported Hardware

• RP2040 boards
  • Raspberry Pi Pico
• Semtech SX1276/77/78/79 based LoRa boards

Default Pinout

Raspberry Pi Pico	Semtech SX1278
3.3V	VCC
GND	GND
GPIO 18	SCK
GPIO 19	MOSI
GPIO 16	MISO
GPIO 7	DIO0 / G0
GPIO 8	NSS / CS
GPIO 9	RESET
GPIO 10	DIO1 / G1

Default Pinout can be overrided with setPins() function

Installation

1. Set up the Pico C/C++ SDK
2. Download module from git and open directory

git clone https://github.com/akshayabali/LoRa-pi-pico.git
cd ./LoRa-RP2040

3. Set PICO_SDK_PATH

export PICO_SDK_PATH="path to pico-sdk"

4. Create build directory then run cmake and make:

mkdir build
cd build
cmake ..
make

Notes

Currently this is only tested on SparkFun MicroMod RP2040+LoRa. Feel free to reach out for any bugs or support.
