PWM on Android

Moderators: chensy, FATechsupport

Hello,

I'm trying to dimming a led with PWM and the libfriendlyarm-hardware.so library but I'm only able to set the frequency and not the duty cycle.

Do you know how can I manage the brightness of my led ?

Thanks
Re,

In absence of any answer..,
Can you provide the source code of your library please ?
Maybe I can implement this by myself.

Thanks
Hi Sidi,

did you make any progress? Currently I am facing the same challenge: controlling a TFT backlight with PWM.

Final result should be integrating the PWM signal into the Android system brightness slider.

@FATechsupport
Any suggestions?
