h1. Changelog 3.1.15

New features:

h3. Direct GPIO support

Introduced control of generic GPIO on various (pi)-platforms to control pins on the 40-pin header directly from javascript. 

This is a first effort of direct IO and only 5 input and 3 output pins are accessible and enumerated as A to E for input and A to C for output.

The mapping for Raspberry Pi platforms is:

Inputs:

A -> pin 29

B -> pin 31

C -> pin 33

D -> pin 35

E -> pin 37

Output

A -> pin 19

B -> pin 21

C -> pin 23

To access the pins via javascript use:

<pre><code class="javascript">

    //To set output level ("high" and "low" is valid)

    Controller.GPIOSetOutputChannel("B","high");

    //To read the output or input channels (will return "high" or "low")

    print(Controller.GPIOGetInputChannel("B"));

    print(Controller.GPIOGetOutputChannel("A"));

</code></pre>

To listen on events:

<pre><code class="javascript">

/**

 * Invoked when any of the GPIO input channels are changing state

 * 

 * @param {String} channel - The input channel. Eg. "A"

 * @param {String} toState - Can be "high" or "low"

 */

function onGPIOInputChange(channel,toState){

    print("onGPIOInputChange - Input channel " + channel + " changed to " + toState);

}

</code></pre>

h3. KIOSK mode

Introduced a way of getting an http session as anonymous when explicit using the name kiosk.html on the first page.

This means that when you create a html page as *kiosk.html* and give that URL to a user it allows the user to access the page without the need for login with user/password.

This is typicaly practical in kiosk applications for public use.

Note that only 1-page applications is supported in this way so if a link to a secondary page is put in kiosk.html the user will be forwarded to the login page!

Clean up:

* Removing the MIRA and BLE5 implementations completely from the platform.

Bug fix:

* Added "Path=/" to cookie response. This is a hack due to lack of support in NanoHTTPD library.
