Hi,

I have developed the POC device using GH3026.

Anyway, I have got felt that the led is brighter than that I expect. So I am gonna change AGC parameters.

I have found those on following screenshot.

I don't understand AMB_SAMPLE and AMB_SLOT_SEL, AGC_RSTRN_THD_H and AGC_RSTRN_THD_L.

How should I change these parameters?

Hi

The soft_agc module does not require manual adjustment, just use the default parameters. Regarding the issue you mentioned about the LED being brighter than expected, you can try turning off the AGC first to see if the default current meets your expected settings
