12864B3 V2.0 openGLCD library problem

hi all.

I have the LCD screen in the photo.
I can not use the pins in the OpenGLCD library. There is no charge for the CS1 CS2 pins.
please help.


It looks like ST7920. It is easiest to use SPI mode. (with PSB pin).

You can use 4-bit parallel or 8-bit parallel if you are a masochist.


openGLCD currently doesn't support that type of GLCD. Have a look at u8glib/u8g2
