IOIO Corvova Plugin

This is cordova android plugin for controlling IOIO OTG It provides javascript inteface to interrcat with the board

Also you will need to read this article to find out how pins work https://github.com/ytai/ioio/wiki/Getting-To-Know-The-Board#detailed-pin-function-table

How to install

You can use plugman to install the plugin

plugman install --platform android --project <path to your project>/platforms/android --plugin https://github.com/AppShed/ioio-cordova-plugin

Requirements

The only requirement is that your IOIO firmware must be up to date. (App-IOIO0500.ioioapp was the latest firmware at the moment of writing this article)

Here is a link that explains how to check your current firmware and update it https://github.com/ytai/ioio/wiki/IOIO-OTG-Bootloader-and-IOIODude

How to use

First of all you need to define port you want to work with. Once IOIO succesfully initialized, led on IOIO started blinking

window.ioio.open({ // start ioio and open ports we need
	inputs: {
		analogue: [37,39,40,41],
		digital:[38]
    },
	outputs: {
		digital:[33],
		pwm: [
			{pin: 10, freq: 1}, // set default frequency for the pin 10
			{pin: 12, freq: 1}
		]
	},
	delay: 200 // Optionally set minimum delay between receiving data from IOIO
}, function() {
	// success
}, function() {
	//fail
}, function(vals) {
	// global all open pin listener

	for(var i=0;i<vals.length;i++){
		var pin = vals[i];
		//for(var key in pin){console.log(key + ":" + pin[key]);}
		switch(pin.class){
			case window.ioio.PIN_INPUT_DIGITAL:
			case window.ioio.PIN_OUTPUT_DIGITAL:
			case window.ioio.PIN_INPUT_ANALOG:
			//pin.pin pin.value
			break;
			case window.ioio.PIN_OUTPUT_PWM:
			//pin.pin pin.freq
			break;
		}
	}
});

You can add some listeners to read values from pins

	window.ioio.addPinListener(37, function(value) { // parameter value is boolean for digital ports and float for other ports in range from 0.00000 to 1.00000
		// todo
	});

	window.ioio.addValuePinListener(37, 0.5, function(value) { // if value goes high that 0.5 it will fire, if it then goes lower, it will fire again
		// todo
	});

And you can control some pins

	window.ioio.setPwnOutput(10, 0);  // set frequency for the pin 10
	window.ioio.setPwnOutput(12, 0); // set frequency for the pin 12
	window.ioio.setDigitalOutput(33, true);  // enable pin 33
	window.ioio.setDigitalOutput(33, false); // disable pin 33
	window.ioio.toggleDigitalOutput(33); // toggle pin 33

Once you finish, you have to close IOIO

	window.ioio.close(); // finish work with ioio
