Hey @josch0 Can I ask you why you closed this PR? I'm asking because I'm building a smart alarm clock and the lowest brightness is too high at night. |

The CTRL pin of the AP3031 is picky regarding the applied PWM frequency. If the frequency is too high, the dimming of the display backlight behaves strangely.
I have achieved the best results and seamless dimming between 0% and 100% with a PWM frequency of about 100Hz. Therefore, a corresponding clkdiv is set in this patch.
