Hi!
The driver for the camera is actually part of the gap_sdk. Have you looked at their issue list if this is a problem?
What I do know that is is important to set the registries before the PI_CAMERA_CMD_STOP as that puts the camera is sleep mode and for some reason makes it irresponsive to registry changes... It seems to be a known bug in the driver. You can perhaps look at the wifi example in these lines for a reference for that. Perhaps that is what is going on?

this change was related to #51 btw
from aideck-gap8-examples.
Thanks for the suggestion! In fact, I am changing the parameters between PI_CAMERA_CMD_START and PI_CAMERA_CMD_STOP commands... In the same way, I was changing some parameters related to automatic exposure control (with AEG ON) and it was working fine, so I thought the parameters related to manual exposure control should also work.
In fact, what I'm trying to do right now (as a workaround) is to leave AEG on and change HIMAX_MIN_DGAIN
and HIMAX_MAX_DGAIN
to the same value I wanted to set DGAIN
to and do the same for other parameters. It sort of works, but I'm still experimenting trying to find out if that approach is reliable.
Anyways, thanks for the suggestion! I've created an issue with gap_sdk [https://github.com/GreenWaves-Technologies/gap_sdk/issues/301], so I think this one can be closed.
