pigpio.rs is a Rust port of the excellent Python library pigpio.py:

http://abyz.co.uk/rpi/pigpio/python.html

This library can be used to write programs communicating with "pigpiod" running on a Raspberry Pi server. "pigpiod" takes care of all the low level stuff needed to do GPIO programming on a Raspberry Pi:

This repository contains a local copy of the original pigpio project (under the directory PIGPIO).

Note: The Rust code has been tested on both a Raspberry Pi 3 and on desktop systems, but not thoroughly.

Installation

Make sure you have Rust installed on the Raspberry Pi. It is easy to do this using "rustup":

https://www.rust-lang.org/en-US/downloads.html

Clone this repository on a Raspberry Pi. The first step is to build "pigpiod". For that,

cd PIGPIO
make pigpiod

You should then run "pigpiod" as root.

Next, build and run the sample program in "main.rs":

cargo run

Before running the Rust code, make sure you set an environment variable:

export PIGPIO_ADDR=localhost

Alternately, you can compile and run the Rust code on your desktop/laptop. In that case, make sure you assign the IP address of the Raspberry Pi as value of the environment variable PIGPIO_ADDR:

export PIGPIO_ADDR=192.168.0.102

(assuming Raspberry Pi is at IP 192.168.0.102)
