Control backlight with P5?
Hey;
I'm trying to control the backlight of the LCD with processing using a pir or IR sensor. The LCD i'm using is this: http://www.waveshare.com/4inch-RPi-LCD-A.htm
on the bottom of the page there are some of the pinouts but i couldn't see a separate GPIO for the backlight.
Is is possible to do it with P5 or do i have to run a separate Python script to control the backlight?
Thanks.
