Getting less data than expected

Question asked by brijesh on Sep 5, 2012
Hello,

I am working on vision module using SMT32F4 and OV7670. It is custom built board and here is more information
http://www.negtronics.com/vision-module

The problem I am having right now is with DCMI/DMA transfer. I am getting less data than expected, basically 4 pixels less per line. Did anyone have this issue? I am not sure if the data that I did receive is correct.

Can any of you guys paste a working sample code? Maybe the issue is with the register setup of OV7670. There is no good data sheet and there seems to be too many undocumented registers. Does anyone have a working register setup for QVGA or QQVGA image capture?

Thanks
