Assuming the LCD uses the common SED1520 graphics controller, the command to config the LCD is
Config Graphlcd = 120 * 64sed , Dataport = Portc , Controlport = Portd , Cd = 2 , Rd = 1 , Ce = 3 , Ce2 = 4 , Reset = 0
You can set the Dataport and ControlPort to whatever you like, and the pins too. LCD CS1 is Ce, CS2 is Ce2.
Place the command
$lib "glcdSED122.lib"
somewhere after the $regfile statement in your code to pull in the graphics library.

| Can you tell what Bascom compiler you are using, AVR or 8051 because you also asked this question in the Bascom 8051 section. |
