I have a 128x64 AGM1264 KS0108 controller GLCD.
I am trying to check if the GLCD is working. Eventually I will be using this with an Atmega328.
Here is the basic hookup I am using to check if the GLCD works:
Pin 1 (vss) ---> GND
Pin 2 (vdd) ---> 5V (I checked vdd at the GLCD connector and it is 5V)
Pin 3 (Vo) ----> GND
Pin 6 (E) ----> 5V
Pin 15 (CS1) ---> 5V
Pin 17 (Reset) ---> GND
Pin 18 (Vee) ---> GND
With the above configuration, shouldn't I see "boxes" on the GLCD?
Could it be the contrast pin?
Do I need a negative power supply for the Vee pin?
Datasheet is attached.
Appreciate any help.
