I'm using the 3MP model on a Raspberry Pi Pico with the full_featured example. Setting manual exposure via the Ardulink app does not change the output image at all, and the image data is returned instantly. Changing the manual gain, values seem very on/off, with huge jumps in sensitivity between integer steps between 1 and 10. Both of these actions are performed after turning off auto exposure / gain.
I wrote a test Web Serial implementation to query over Ardulink, and ReportCameraInfo says:

Is the correct register being used? I've noticed that this varies in implementations, for example CAM_REG_MANUAL_EXPOSURE_BIT_7_0 is 0x35 in https://github.com/ArduCAM/Arducam_Mega/blob/3e7eb78bfcabf80aeafd05c2c040760ca69adc49/src/Arducam/ArducamCamera.c#L65 and it is 0x2f in https://github.com/ArduCAM/Arducam_Mega/blob/3e7eb78bfcabf80aeafd05c2c040760ca69adc49/examples/RaspberryPi/capture/Arducam.c#L61
Thanks!
