Hello everyone,

I'm an owner of a LPC43xx - MCB4300 board, and I want, as a first step, to use a camera as a webcam through USB on my board.
I want the camera to take a snap and send it through USB to the PC.
I've read a lot about Cameras, USB class, descriptors, and so on, I've also seen the LPCOpen which provide some USB examples based on the LPCUSBLib, usbd rom.

I would like to know if there is any example code on virtual camera using USB, any example using camera like webcam with LPC18xx/LPC43xx or if someone would have any hint, it would be grateful.

Thank you,

Regards,
Ahmed.

Hi,

I wrote the USB Descriptors for a USB Video Device for my Thermal Camera project. I used the LPC1768, but the relevant code should be portable without major changes.

You can find the code here : https://bitbucket.org/konstantin_werner/leptonusbvideo

The descriptors are in /usb/usbdesc.c, the UVC handler functions are in /usb/video/videouser.c.

See the readme for some hints on how to get data from the device under Linux.

Best regards

Konstantin

Hi TheFallGuy,

Thank you for your answer, however, I've already seen this AN, and the 2 others provided by LPC on camera interface, the fact is they just explain how to send data from camera to SRAM using SGPIO etc.. to LCD.

What I want is doing the same without LCD and then send the snap through the USB to a PC.
I'm looking for examples on the "USB" part, to see how descriptors are configured for sending snaps or video etc..

Thank you very much,

Regards,
Ahmed
