Hello Hans, I've picked up work on the sur40 driver again recently. There is one major feature left that is currently unsupported by the Linux driver, which is the hardware-based calibration. The internal device memory contains a table with two bytes for each sensor pixel (i.e. 960x540x2 = 1036800 bytes) that basically provide individual black and white levels per-pixel that are used in preprocessing. The table can either be set externally, or the sensor can be covered with a black/white surface and a custom command triggers an internal calibration. AFAICT the usual V4L2 controls are unsuitable for this sort of data; do you have any suggestions on how to approach this? Maybe something like a custom IOCTL?
