This project enables simulation of a device which might be accessed via mraa. Currently this library supports I2c, SPI, and GPIO. This project provides several benefits:
The following example is based on an imaginary ‘light bulb’ device abstraction, which exposes a value of brightness over a mraa-provided interface. Please see the test/index.js
file for an example.
You may install mraaStub
from npm like this:
npm install mraaStub
Since we often switch between a mraaStub and the real mraa library, we suggest creating an index.js
file inside a lib/mraaSwitcher
folder.
/* index.js - file for switching between mraa and mraaStub */ // Define the conditions under which the mraaStub should be loaded var platform = require('os').platform(); var m; if (platform === 'win32') { m = require('mraaStub'); } else { m = require('mraa'); } module.exports = m;
You can add this to your project in its own lib/mraaSwitcher/index.js
file and use require('../mraaSwitcher')
everywhere!
