I've just received my graphical lcd from crystal fontz (the cfa32020c-fmi-t) and was wondering if anyone has any initialization/test code available. I'm connecting it to a Pic18F4450.
Also, I'm trying to connect everything and am confused on the ccfl backlight hook up. It appears that the voltage rating is ac and a high voltage. Is this true? Also, which pin is positive and which is gnd?
I've been trying to get it powered by connecting the vo, vee, and vdd to a pot as pictured in the datasheet, and here's what I have. When I power it on and turn the pot, the lcd goes from light green/yellow to a bluish color. Is this right? This is only with vo, vee, pot, vss, vdd, and frame gnd connected. Also, am I suppose to conect vee to an external power or is this step up from 5v inside the lcd?
Thanks for your help.
