I need to have control over the exposure and shutter speed of the cameras. If I run ‘list_format’ then the only controls it shows are h-flip and v-flip;
index: 0, CID: 0x00980914, desc: V4L2_CID_HFLIP, min: 0, max: 1, default: 0, current: 0
index: 1, CID: 0x00980915, desc: V4L2_CID_VFLIP, min: 0, max: 1, default: 0, current: 0
I know that the camera does support exposure and shutter speed controls since I can set them using raspistill. Raspistill won’t let me use the full resolution of the cameras so I need a solution using MIPI.
Is it possible to write directly to the control registers? Looking at the OV5647 specification, register addresses 0x3500 - 0x3503 control the exposure. Could I write to these registers from the Pi to set the controls that I need? Is it possible to access the i2c to each of the two cameras?
