I've hooked up a CFAG160160B to a P18F4520 an have the necessary graphics routines working well. However, my display has a slight flicker. I don't beleive this has anything to do with reading/writing of the display as when the pic is idle the display is still flickering. Looking at Vo I see that it has about 0.5V of random noise. As per datasheet it is set for ~-12.4V from the Vee output using a 10K pot. Looking a Vee, apart from high frequency noise, this is clean. So to is the Vdd supply. I'm still able to develope my application but it would be nice to solve the flicker problem. Any suggestions are welcome!
