Issues with Intel Edison MRAA module

0 votes

I recently downloaded the Intel XDK IOT version and used the LED pin 13 Blink sample. I then uploaded the program onto the Edison, but it came up with a few errors; One of them being that it could not find the MRAA module. The sample code that came with it was: main.js:

var mraa = new require("mraa"); //require mraa
console.log('MRAA Version: ' + mraa.getVersion()); //write the mraa version to the Intel XDK console

var myOnboardLed = new mraa.Gpio(13); //LED hooked up to digital pin 13 (or built in pin on Galileo Gen1 & Gen2)
myOnboardLed.dir(mraa.DIR_OUT); //set the gpio direction to output
var ledState = true; //Boolean to hold the state of Led

periodicActivity(); //call the periodicActivity function

function periodicActivity()
{
  myOnboardLed.write(ledState?1:0); //if ledState is true then write a '1' (high) otherwise write a '0' (low)
  ledState = !ledState; //invert the ledState
  setTimeout(periodicActivity,1000); //call the indicated function after 1 second (1000 milliseconds)
}

package.JSON:

{
  "name": "Onboard LED Blink App",
  "description": "",
  "version": "0.0.0",
  "main": "main.js",
  "engines": {
    "node": ">=0.10.0"
  },
  "dependencies": {
  }
}

You can work on this choice:-

  1. In the XDK IDE, there's a dropdown settings control just above the serial / terminal area on the right. If you drop down this list, it has options to update all of the libraries and node daemon. This is an easier way to make sure MRAA and all the other deps on the board are up to date and configured properly.
