hi I'm going to store JPEG data in an array and then decode itI'm using H7A3ZI-Q for the board uint16_t outdatabuffer [65535] ={0};JPEG_Decode_DMA(&JPEG_Handle,(uint32_t)frameBuffer,bufferPointer , outdatabuffer);I used this code, but only 0 was save...

I'm trying to get image data through DCMI using ov2640, but other pins' signals come out well, but D0's signals don't show waveformsHardware connectivity is no problem. Is there anything I should pay attention to in software or clock?

hello OV2640 is used as the camera module I use this fuction  HAL_DCMI_Start_DMA(phdcmi, DCMI_MODE_SNAPSHOT, frameBuffer, length);  And I'm going to receive data through UART.However, the data is not coming. If you have any good ideas, please let me ...
