New page

{{Under_Construction}}

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

== Introduction ==
I bought a low-cost webcam on LDLC some years ago. This USB webcam works on Linux with the GSPCA driver. 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 on 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.
