How to access GPIO on Android


#21

您好,关于gpio的number号,是如何计算的?为什么GPIOH5: 176

Question:

I understand how to get to root with su for the GPIO.

For the other options, how do you do it ?

2 Let the 3rd application as system process

Is this one just putting the app in priv-app in the rom ?

3 Open the permission for 3rd application on system

This one i don’t know how. Can you point me in the right direction ?

Thanks

You also need a system signature for the app.

You need to modify source code of the direction system/sepolicy
