thank you for clarifying about the voltage level for Vo.
A few days ago, I asked for some sample code to control the
CFAG12864BW-GHN. Unfornately, I had to reinstall my machine and lost that code. Can you please send or post that code again.
Thank you very much.
Hello, i have a CFAH4002A-YYH-JP. But i have a similar question about Vo. If i put Vcc = 5V, and Ground = 0v, so PIN3 (Vo) must be 0v? Because in datasheet i read :
supply Voltage For LCD VDD-V0 4.5 V (Typical)
You are correct. But a 5v Vlcd may make the display a bit dark. You should have Vo be adjustable from 0v to about 2v (or 5v, as shown in the data sheet), by using a potentiometer, as shown. Then you can optimize the contrast setting.
