請教各位老師,我由于對12864LCD顯示屏不太了解,最近搞了個12864顯示程序,為什么LCD里面只顯示"中國南京市雨花臺"為什么"區(qū)"自無顯示呢,應(yīng)該在第二行顯示才對.請各位老師指教,謝謝!
原程序如下:
#define RS RD2 //DI
#define RW RD3
#define E RD4
#define CS1 RD7
#define CS2 RD6
#define RST RD5
#define LED3 RC4
#define LED4 RC5
#define LED2 RD0
#define LED1 RD1
unsigned char PAGEADD; //存放頁地址寄存器
unsigned char PAGENUM; //存放總頁數(shù)寄存器
unsigned char CLMSUM; //存放總列數(shù)寄存器
unsigned char CLMADD; //存放列地址寄存器
unsigned char WRITE; //存放顯示數(shù)據(jù)寄存器
unsigned char row; //存放顯示起始行寄存器
unsigned char i,k; //通用寄存器
const char table[]=
