# lora_aprs_node_pico
LoRa communication for Raspberry Pi RP2040 Microcontroller. 

This program is written for 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 setPins() function

## Installation

1. [Set up the Pico C/C++ SDK](https://github.com/raspberrypi/pico-sdk)
2. Download this repo
3. Set `PICO_SDK_PATH`
```sh
export PICO_SDK_PATH="path to pico-sdk"
```
4. Create `build` directory then run `cmake` and `make`:
```sh
mkdir build
cd build
cmake ..
make
```
## Notes
Currently this is only tested on Raspberry Pi Pico and Semtech1278 board. Feel free to reach out for any bugs or support.
