Hi. I'm using STM32U585 with OV5640 to capture the image. I set the DMCI synchronization to hardware to us Hsync and Vsync. However, I set the camera to send JPEG image rather than raw image, so the frame size is unknown. Now the problem is that it's...

Thanks @KDJEM.1 .True. GPDMA_CxBR1[0:15] shows the remaining bytes. So far, there are two ways to see where the DMA is at a certain point:hdcmi.DMA_Handle->Instance->CBR1 & 0x0000FFFF : tells how many more bytes remains to be transferred.hdcmi.DMA_...

I think I found a way. But I'm not sure if it's the best way to do so.I'm reading the CDAR register (hdcmi.DMA_Handle->Instance->CDAR). Assuming that it's pointing to next byte location, I can calculate the already transferred bytes by subtracting th...
