Common API for Tibbo's GPIO Modules

The node module for GPIO tibbits, like buttons, leds, relays and isolated inputs.

This package is deprecated!

Please, use https://www.npmjs.com/package/node-libgpiod instead

NEW GPIO code installation (package.json)

  "dependencies": {
    ...
    "@tibbo-tps/pinmap": "^0.0.x",
    "@tibbo-tps/socket-name-parser": "^0.0.x",
    "node-libgpiod": ">=0.3.0",
    ...
  },

NEW GPIO code usage

const TPSpmap = require( '@tibbo-tps/pinmap');
const { version, Chip, Line } = require( "node-libgpiod");

global.chip = new Chip(0);
global.led = new Line( chip, TPSpmap.getRpin( "S15A"));

led.requestOutputMode();
led.setValue(1);

Please, see an example of GPIO usage in Wiegand app https://github.com/tibbotech/wiegand-demo/blob/master/modules/led.js

Installation Instructions

Install the module

npm install @tibbo-tps/gpio

Usage

var led = gpio.init("S13A");
led.setDirection("output");
led.setValue(0);

API Methods:

init(line)

• line - TPP line code in form: S{socket number}{pin letter}, where pin letter is A, B, C or D. E.g. S15A, S3D

Returns an object with the following methods:

.setDiection(direction)

• direction - 'input' or 'output'. Use 'input' for buttons, 'output' for leds.

.getDiection()

Returns direction, 'input' or 'output'.

.setValue(value)

• value - 1 for HIGH or 0 for LOW

Sets line state.

.getValue()

Returns line state.

Example:

var gpio = require("@tibbo-tps/gpio");

var led = gpio.init("S13A");
led.setDirection("output");

var value = 0;

setInterval(function(){
    led.setValue(value);

    value = value === 1 ? 0 : 1;
},1000)
