PWM on PORTG pin 3 on a 18F67k22

[longpole001]

ok thanks richard i am tryng the to get a contrast control working for neg voltage , came across this example , see attached

i still want to have a trim pot , which will set the default value so the lcd is viewable regardless , as well a setting it up via software , to get better viewable / allow temperature change

have you come across other working examples for negative bios contrast controls
