| − | 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.
