In this tutorial we'll see, how to interface 128*64 GLCD with PIC16F877A Starter board. We will be using KS0108 controller based JHD12864E display. There are many displays out there based on KS0108 or compatible display controller. They all work the same way, but make sure to check the datasheet for the pin diagram before doing the connection.


Prerequisites

Please check this tutorial for detailed explanation on GLCD.


Hookup

Below table shows the GLCD pins connection. Please check glcd.h file for pin configuration.

RS RW EN CS1 CS2 D0 D1 D2 D3 D4 D5 D6 D7
PD_0 PD_1 PD_2 PD_3 PD_4 PB_0 PB_1 PB_2 PB_3 PB_4 PB_5 PB_6 PB_7


Displaying Strings

#include "glcd.h" //User defined LCD library which contains the lcd routines
#include "delay.h"
/* start the main program */
void main()
{
/* Initialize the glcd before displaying any thing on the lcd */
GLCD_Init();
GLCD_Printf("Interfacing\n\n");
GLCD_Printf(" KS108 128x64\n\n");
GLCD_Printf(" With Pic16f877a");
GLCD_GoToLine(6);
GLCD_Printf(" ExploreEmbedded");
while(1);
}

Displaying Numbers

#include "glcd.h"
#include "delay.h"
void main()
{
int count=0;
GLCD_Init();
GLCD_DisplayString(" Displaying Numbers");
while(1)
{
GLCD_GoToLine(2);
GLCD_Printf("hex:%4x \n\ndec:%5d \n\nbin:%16b",count,count,count);
DELAY_ms(100);
count++;
}
}

Displaying Bar Graphs

#include "glcd.h"
void main()
{
GLCD_Init();
GLCD_HorizontalGraph(0,45);
GLCD_HorizontalGraph(1,50);
GLCD_HorizontalGraph(2,82);
GLCD_HorizontalGraph(3,74);
while(1);
}

#include "glcd.h"
void main()
{
GLCD_Init();
GLCD_VerticalGraph(0,45);
GLCD_VerticalGraph(1,50);
GLCD_VerticalGraph(2,82);
GLCD_VerticalGraph(3,74);
while(1);
}
