gain maxes out at 32

The docs say you can set a gain ceiling up to 128, but if you print out the gain continuously, it never exceeds 32 (well, 29.82729, but that’s the gain returned by get_gain_db() that corresponds to a setting of 32). Setting it to 64 or 128 doesn’t push it up any higher. I tried setting the ceiling both through set_auto_gain() and set_gain_ceiling(), as well as setting the gain (not the ceiling) to those higher values through set_auto_gain().

I think 32 is the max, not 128. Thoughts?

It’s only 128 for the OV2640. 32 is the max for the OV7725.

Thanks. That’s fine. Just wanted to understand what was going on.
