<article class="page_pi_cap"><h1>Pi Cap</h1>
|
||
<p>The Pi Cap adds precise capacitive touch, distance sensing and high quality audio to any Raspberry Pi with a 40 pin GPIO connector. The 12 electrodes can be connected to anything conductive to create a touch or proximity interface. Additionally the Pi Cap includes a user-programmable RGB LED and a multi-function button.</p>
|
||
<p>The Pi Cap software is in the official Raspbian repository, so to install the software simply enter:</p>
|
||
<pre><code class="language-bash">sudo apt-get update
|
||
sudo apt-get dist-upgrade
|
||
</code></pre>
|
||
<p>Reboot the Raspberry Pi and enter:</p>
|
||
<pre><code class="language-bash">sudo apt-get install picap
|
||
picap-setup
|
||
</code></pre>
|
||
<p>The Pi Cap provides 7 digital I/O pins, brought out from the 40-way Raspberry Pi GPIO connector – pins 12, 13, 15, 16, 18, 22, 36. The Pi Cap package contains plenty of code examples written in C++, Python and Node.js that are supported by the Pi Cap library.</p>
