GPIO in/output using IR pins on Generic Amlogic S905

[Ricardo JL Rufino]

Hi, I always had the desire to understand if it is possible to use the pins of the IR sensor, as general input / output to control sensors and actuators ?!
What would be the steps to allow this?

 

My Board:

TX8 PRO / Amlogic S905W
