Auto brightness with PIC (PWM) and LDR for Lilliput 701 LED Backlit
Has anyone tried using a microcontroller to control the brightness of the LED backlight in a Lilliput? To my understanding, the monitor isn't actually controlling the brightness of the backlight, it's just simply controlling the contrast and so on. I'm measuring the voltage to the LED backlights and it's pretty much staying a constant 9.4V while adjusting contrast and brightness through the menu function.
Just curious to see if anyone else has done this before I try it. I know I can do it but if someone else has already experimented with it would be nice :cool:
