How to access GPIO on Android

[Terry]

Hi, TomasFilip:
Are you a developer?

@TomasFilip

I would like know, how I can control PWM_AO_A and PWM_F signals.

You can try to set the register up to Amlogic S905X Datasheet.
If you has question about it , I will provide some advices for you.

@TomasFilip

but don’t what kind of is. (using bash scripting under su)

You can copy your bash scripting into the path ‘/system/etc/init.d/’ when you on Vim_Marshmallow_Root_170603

@TomasFilip

note: I2S is enabled (acording info here), so GPIOH_x signals are gone. Any way how to get GPIOH_5 signal back? And keep I2S bus working

It is impossible and only one function will be used on the same time.
