Pigpio-mock

Article: https://viktorkirilov.me/post/mocking-raspberry-gpios/

A mock library used for raspberry pi development on your local machine. It copies all method from https://github.com/fivdi/pigpio and logs information to the console, instead of controlling the Raspberry's GPIO pins.

Example

You can also check examples folder.

const Gpio = require("pigpio-mock").Gpio;
const led = new Gpio(13, { mode: Gpio.OUTPUT });
let dutyCycle = 0;

setInterval(function() {
	led.pwmWrite(dutyCycle);

	dutyCycle += 50;
	if (dutyCycle > 255) {
		dutyCycle = 0;
	}
}, 500);

should output:

[GPIO 13 / constructor] Initializing...
[GPIO 13 / constructor] Setting mode = 1
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 0
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 50
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 100
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 150
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 200
[GPIO 13 / pwmWrite-analogWrite] Setting dutyCycle = 250

Installation

It is as simple as:

yarn add pigpio-mock

and you can use it in your code as:

const pigpio = process.env.NODE_ENV !== "production" ? 
    require("pigpio-mock") : 
    require("pigpio");

Implemented classes:

• Gpio
• GpioBank
• Notifier
