Screen Brightness

[kjacobs]

Is there a way to adjust the brightness of the PiScreen? I’m using it for a clock beside my bed and it’s very bright in a dark room. I know there’s a binary on/off setting in software and hardware but I was looking for something variable.

GPIO 22 is used for the backlight and it is possible to make the TFT dim using PWM.

Try this

git clone https://github.com/mwilliams03/pi-blaster.git
cd pi-blaster/
make
sudo ./pi-blaster 22
echo "0=.5" > /dev/pi-blaster
echo "0=1" > /dev/pi-blaster
