-= Raspberry Pi camera/LED demo
-
-== Overview
-
-The link:/[demo] consists of web app providing access to a webcam and a LED attached to a RaspberryPi.
-The device is assumed to have a limited bandwidth towards the server hosting the web app.
-
-== Objective
-
-The demo shows how to use websockets to communicate bidirectionally with an embedded device using standard protocols.
-
-It also shows that it's possible to use Smart.c to develop also the cloud endpoint and expose WebSocket and RESTful APIs
-easy to integreate with modern web stacks.
-
-== How it works
-
-image::docs/arch.png[]
-
-There are two components, once with runs on the device (`device_side`) and one that runs on a stronger machine
-and with more bandwidth (`cloud_side`).
-
-The device app connects to the cloud app via websocket and sends a new jpeg frame as fast as the underlying `raspistill` camera
-grabbing application can handle. The device automatically attempts reconnecting.
-
-The cloud side serves the webapp static pages and serves an MPJEG image on `/mpjg`.
-The MPJEG image handler blocks all the clients until a JPEG frame arrives via websocket
-and then every client will receive a copy of the frame.
-
-The web app can turn on and off the LED via a RESTful api accessible via the `/api` handler.
-
-== Installation
-
-=== Server side
-
-----
-git clone https://github.com/cesanta/mongoose
-cd mongoose/examples/web_demo
-make cloud_side && ./cloud_side 0.0.0.0:8080
-----
-
-=== Raspberry Pi
-
-The instructions provided here are tailored for the Raspbian distribution.
-
-==== Dependencies
-
-jpegoptim::
-apt-get install jpegoptim
-
-camera::
-run raspi-config and enable camera
-
-==== LED
-
-In order to access the led on your link:http://www.qdh.org.uk/wordpress/?page_id=15[HotPi]
-board you need to export the gpio pins:
-
-----
-for i in 22 23 24; do
-  echo $i >/sys/class/gpio/export
-  echo out >/sys/class/gpio/gpio$i/direction
-  chgrp pi /sys/class/gpio/gpio$i/value
-done
-----
-
-==== Build and run
-
-----
-git clone https://github.com/cesanta/mongoose
-cd mongoose/examples/web_demo
-make device_side && ./device_side yourserver:8080

-<div class="sectionbody">
-<div class="paragraph">
-<p>The <a href="/">demo</a> consists of web app providing access to a webcam and a LED attached to a RaspberryPi.
-The device is assumed to have a limited bandwidth towards the server hosting the web app.</p>
-</div>
-</div>
-</div>
-<div class="sect1">
-<h2 id="_objective">Objective</h2>
-<div class="sectionbody">
-<div class="paragraph">
-<p>The demo shows how to use websockets to communicate bidirectionally with an embedded device using standard protocols.</p>
-</div>
-<div class="paragraph">
-<p>It also shows that it&#8217;s possible to use Smart.c to develop also the cloud endpoint and expose WebSocket and RESTful APIs
-easy to integreate with modern web stacks.</p>

-<div class="paragraph">
-<p>There are two components, once with runs on the device (<code>device_side</code>) and one that runs on a stronger machine
-and with more bandwidth (<code>cloud_side</code>).</p>
-</div>
-<div class="paragraph">
-<p>The device app connects to the cloud app via websocket and sends a new jpeg frame as fast as the underlying <code>raspistill</code> camera
-grabbing application can handle. The device automatically attempts reconnecting.</p>
-</div>
-<div class="paragraph">
-<p>The cloud side serves the webapp static pages and serves an MPJEG image on <code>/mpjg</code>.
-The MPJEG image handler blocks all the clients until a JPEG frame arrives via websocket
-and then every client will receive a copy of the frame.</p>
-</div>
-<div class="paragraph">
-<p>The web app can turn on and off the LED via a RESTful api accessible via the <code>/api</code> handler.</p>
