Hello everyone, I have a little but very annoying problem.
Please help me with common advice about how I can better solve this problem.
I used OpenMV3 but without OpenMV software, only hardware. I can read and write I2C register, but when I start to read data by protocol DCMI (GRB565) i receive every time only this value - “537213536”
At first, I want only to receive images from the camera. Maybe you can give recommendations for register setting and for code. I used HAL library and the next code
uint32_t AddressFrameBuffer[0x25800]; // i am not sure about this valueб is it amount of pixels?
uint32_t DataSizeImageSensor = 0x25800; // (uint32_t)((IMG_ROWS * IMG_COLUMNS * 2) / 4))
HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_SNAPSHOT, (uint32_t)AddressFrameBuffer, DataSizeImageSensor);
