Hi Jeremiah,
I am using PIC 18F452, with the following drivers for displaying data on the GLCD but don't how to use these drivers with Graphics header file, these drivers was provided by the GLCD manufacturers for 8051 Micro Controller, I changed the code to use with PIC 18F452 now it is displaying some data on the screen (but unfortunately most of data displaying on the screen is garbage) .
| Code: |
#include<18F452.h>
#include<stdio.h>
#include<stdlib.h>
#use delay(clock=20000000)
#define uchar char
#define uint int
#DEFINE wr PIN_B0
#DEFINE rd PIN_B1
#DEFINE cs PIN_B2
#DEFINE cd PIN_B3
#DEFINE rst PIN_B4
uchar zimu[8][93]=
