Hi,
I want to implement DCMI on the STM32F429I Discovery using OV7670. I am using external clock of 20MHz for OV7670 clock source. I can get the frame interrupt, but cannot get the dma interrupt working. Also, no data is written to the buffer. My code is posted below. So my question is can i actually implement DCMI with STM32F429 and use lcd at the same time? I am using lcd driver without ltdc, so the dcmi pin is still not used. And, how can I write data received to DCMI to the data buffer? Any help will be greatly appreciated

Thanks

Vincent
