lora_aprs_node_pico

A simple LoRa APRS module which can be used as a remote data logger and/or remote I/O controller. See my website for more information: https://www.meezenest.nl/mees-elektronica/RPi-pico-LoRa-APRS.html. It is an evolution of another project of mine: https://www.meezenest.nl/mees-elektronica/aprs_telemetry.html

This program is written for the RP2040 C++ SDK.

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 the setPins() function

Installation

1. Download this repo
2. Set PICO_SDK_PATH to included pico-sdk

export PICO_SDK_PATH="path to pico-sdk"

3. Create build directory then run cmake and make:

mkdir build
cd build
cmake ..
make

Notes

I added the pico-sdk to prevent compatibility issues. Probably not a recommended practice, but there you go!
