Description: Just put the pictures saved to the SD card, BMP format. Because the program was originally the data directly from the DCMI DMA to the LCD in order to get smooth, so you want to save, then you must first by the RAM for the transition, it is impossible while reading camera data while saving to the SD card, and certainly can not keep up, but with the RAM buffer, then save the images you need QVGA 150K, in order to save RAM, I put the LCD as a temporary memory, DMA transfer is stopped to take pictures and put the data on branches read LCD come back to the SD card, plus head to BMP, JPG encoding after free and then get hold of the saved. due to different LCD driver chip to read back the data format may be followed by written into different series like ILI932 read out the is BGR565, need to convert, get attention.
