raspi-io-server-utils

This package contains useful classes for the Raspberry Pi.
TypeScript support included.

Changes: See CHANGELOG.md.

Usage

ES6 example:

``js
// JavaScript
const { DigitalInput, DigitalOutput } = require( 'raspi-io-server-utils' );

// TypeScript
import { DigitalOutput } from 'raspi-io-server-utils/dist/src/io/digital-output';
import { DigitalInput } from 'raspi-io-server-utils/dist/src/io/digital-input';

const input = new DigitalInput( 11 );
const output = new DigitalOutput( 13 );

input.on( 'enable', () => {
output.enabled = !output.enabled;
} );
`

AVPlayer

Starts audio/video files with VLC, mplayer, or omxplayer, whatever is available.

`typescript
import { AvPlayer } from 'raspi-io-server-utils/dist/src/avplayer/av-player';

const player = new AvPlayer( [ 'vlc', 'omxplayer' ] );
player.play( 'movie.mp3' ).catch(
( err ) => console.error( 'Playback error', err )
);
`

IO

An extension to rpio with events on digital input/output pins
and status report as JSON.

Note: Newer rpio and kernel combinations may cause freezes when hooking up interrupts.
See 4.14 freezes when GPIO is pulled high
and add dtoverlay=gpio-no-irq to /boot/config.txt` for a workaround.

Vector clock

Small class implementing a Vector Clock for ordering asynchronous events.
