lora_aprs_node_pico

A LoRa APRS KISS modem with PE1RXF telemetry support for use 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

Software v1.0.5 (tagged) is suitable for I/O controller without I2C sensors and without telemetry

Software v1.1.0 is suitable for I/O controller with additional support for I2C sensors and PE1RF telemetry. If no I2C is found it will try to continue without telemetry. But that function is experimental.

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

Installation

Download this repo
Set PICO_SDK_PATH to included pico-sdk

export PICO_SDK_PATH="path to pico-sdk"

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!
