JulienL: Add USB webcam support to your Armadeus board

Add USB webcam support to your Armadeus board

New page

{{Under_Construction}}

On this page, you will find some information to add USB webcam support to your Armadeus board.

== Introduction ==
Some USB webcam works on Linux with the GSPCA driver (like the low-cost webcam of LDLC). The source of this driver is now included in the current Linux kernel (starting 2.6.27). Because I don't hold any LCD screen for the moment, the next step is to stream webcam image over the Internet.

== Find your webcam model ==

In order to find your webcam model, you can connect your USB webcam to your computer and use dmesg.

<pre class="host">
[ ] $ dmesg
...
usb 1-1: New USB device found, idVendor=04fc, idProduct=0561
</pre>

With idVendor and idProduct you might be able to find the module to install. For GSCPA based wecam, a list is given in the Linux kernel documentation and can be found here :

<pre>
<...>/linux-2.6.xxx/Documentation/video4linux/gspca.txt
</pre>

In my case, the support of the spca561 module need to be added.

== Install driver ==

Since GSPCA is incuded in the Linux kernel, you can use the following commands to install it.

<pre class="host">
[ ] $ cd armadeus/
[ ] $ make linux26-menuconfig
</pre>

Then you need to choose the right driver. In the case of the LDLC webcam :

<pre class="config">
Device Drivers --->
Multimedia devices --->
[*] Video capture adapters --->
[*] V4L USB devices --->
<M> GSPCA based webcams --->
<M> SPCA561 USB Camera Drivers
</pre>

Now you can build the kernel and update the board.

<pre class="host">
[ ] $ make
</pre>

== Loading driver ==

As you can see, your device is now recognized as a camera.

<pre class="apf">
# dmesg
...
usb 1-1: new full speed USB device using mxc-ehci and address 3
usb 1-1: New USB device found, idVendor=04fc, idProduct=0561
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-1: Product: Generic Digital camera
usb 1-1: Manufacturer: Sunplus Technology Co., Ltd.
usb 1-1: configuration #1 chosen from 1 choice
</pre>

You can load the kernel module using modprobe :

<pre class="apf">
# modprobe gspca_main
Linux video capture interface: v2.00
gspca: main v2.4.0 registered
# modprobe gspca_spca561
gspca: probing 04fc:0561
gspca: probe ok
usbcore: registered new interface driver spca561
spca561: registered
</pre>

To access your webcam, look at /dev/video0.
