hi all

I want to do basic image processing using LPC2148 so i want to
interface camera to LPC2148.

does any one know how to interface a USB camera to LPC2148 and which
USB camera is best for this purpose.

please suggest me other techniques to interface camera to LPC2148

bye

I don't think it can be done with just the LPC2148.
Its USB controller can only act as a device (slave), not as a host
(master).

I stumbled across this interesting ARM720T with camera interface:

Looks interesting since it has direct camera interface, ethernet, 
compactflash, and I2S audio.
It also has an MMU so you could run linux on it with SDRAM.
Looks like an NDA with Epson is required to get the technical details.

If you really want to have fun, go spend $80 on a Linksys
NSLU2, and then boot your own version of Linux on it ...

It has a network interface, and a USB host interface. It
should be trivial to attach a USB camera. If the camera is
supported by Linux, it'll be supported on this hardware.

I just purchased an NSLU2, it hasn't arrived yet. When I
get it and a give it a few tests, I'll post my findings.

FYI: It uses an XScale ARM processor, so I hope this is not
considered too off topic :)

Grab a Linksys WRT54G if you want to play with MIPS :)
