Introduction

The sx1262_driver project provides a clean, maintainable, and hardware‑accurate Python driver for the Semtech SX1262 LoRa transceiver. Unlike many hobby‑grade libraries, this driver is built with architectural rigor, predictable timing, and explicit separation of concerns, making it suitable for real‑world mesh networking, experimentation, and educational use.

The driver targets Raspberry Pi devices running Linux, where the required low‑level interfaces—SPI, GPIO, and IRQ‑driven event handling—are available and behave consistently. Windows and macOS environments do not expose the necessary hardware layers, so all building, testing, and hardware‑in‑the‑loop development must be performed on a Pi.

At its core, the driver provides:

• A minimal, explicit API for configuring and controlling the SX1262
• A robust IRQ/event loop that cleanly separates hardware events from application logic
• Safe handling of busy states, FIFO operations, and transitional IRQ conditions
• A structure that encourages readability, testability, and future extension (e.g., higher‑level mesh protocols)

The project includes example scripts demonstrating basic transmit/receive flows, along with a reproducible build workflow for packaging and installing the driver on a Raspberry Pi.

Building the driver

You must build the driver on a raspberry pi device. This is the intended target.

To build this driver. use the following steps

install required system packages

sudo apt update sudo apt install -y python3 python3-pip python3-venv python3-dev build-essential

Install the back end

pip install --upgrade build

Clone the repo onto the Raspberry Pi device

git clone https://github.com/Lebovitz-Net/sx1262_driver.git cd sx1262_driver

Project structure looks like this

sx1262_driver/ pyproject.toml README.md LICENSE sx1262_driver/ init.py ... examples/ scripts/

Build the package

python3 -m build

The project will produce the folling

dist/ sx1262_driver-.tar.gz sx1262_driver--py3-none-any.whl

Install the package on the Pi

Install the Wheel

pip install dist/sx1262_driver-*-py3-none-any.whl

Or Install the source distribution

pip install dist/sx1262_driver-*.tar.gz

Verify Installation

python3 from sx1262_driver import SX1262 radio = SX1262()

Run the examples

python3 examples/listener.py python3 examples/tx.py

these import the installed Package

from sx1262_driver import SX1262

Install directly from GitHub

You can also install the package directly from this repository (useful for CI or testing):

pip install git+https://github.com/Lebovitz-Net/sx1262_driver.git
