arkadaşlar HiTech için ks0108 tabanlı GLCD için elinde kütüphane ve isis örneği olan yükleyebilirmi foruma.
CCS C için var sanırım hitech c için dönüşüm yapablirsin.

//// This file contains drivers for using a LGM12864B-FL-YBW with ////
//// a KS0108 display controller. This GLCD is 128 by 64 pixels. ////
//// The driver treats the upper left pixel as (0,0). ////
//// ////
//// Use #define FAST_GLCD if the target chip has at least 1k of RAM ////
//// to decrease the time it takes to update the display. ////
//// glcd_update() must then be called to update the display after ////
//// changing the pixel information. ////
//// See ex_glcd.c for suggested usage. ////
//// See KS0108.c for controlling a single 64 by 64 display ////
/////////////////////////////////////////////////////////////////////////

//// LCD Pin connections: ////
//// (These can be changed as needed in the following defines). ////
//// * 1: Chip Select 1 is connected to B1 ////
//// * 2: Chip Select 2 is connected to B0 ////
//// * 3: VSS is connected to GND ////
//// * 4: VDD is connected to +5V ////
//// * 5: V0 - LCD operating voltage (Constrast adjustment) ////
//// * 6: R/S - Register select is connected to B2 ////
//// * 7: R/W - Read or Write is connected to B3 ////
//// * 8: Enable is connected to B4 ////
//// *9-16: Data Bus 0 to 7 is connected to port D ////
//// *17: Reset is connected to B5 ////
//// *18: Negative voltage is also connected to the 20k Ohm POT ////
//// *19: Positive voltage for LED backlight is connected to +5V ////
//// *20: Negavtive voltage for LED backlight is connected to GND ////

/////////////////////////////////////////////////////////////////////////
//// ////
//// glcd_init(mode) ////
//// * Must be called before any other function. ////
//// - mode can be ON or OFF to turn the LCD on or off ////
//// ////
//// glcd_pixel(x,y,color) ////
//// * Sets the pixel to the given color. ////
