1、#include #include #define uchar unsigned char#define uint unsigned inttypedef struct typFNT_GB16 / 汉字字模数据结构signed char Index2; / 汉字内码索引char Msk32; / 点阵码数据;/*TS12864A-3 端口定义*/#define LCD_data P0 /数据口sbit LCD_RS = P35; /寄存器选择输入 sbit LCD_RW = P36; /液晶读/ 写控制sbit LCD_EN = P34; /液晶使能控制sbit LCD_PSB = P37;
2、/串/并方式控制sbit cs = P32;sbit wela = P26;sbit dula = P27;uchar t0;uchar code dis = “0123456789“;#define delayNOP(); _nop_();_nop_();_nop_();_nop_();/uchar IRDIS2;/uchar IRCOM4;/void lcd_pos(uchar X,uchar Y); /确定显示位置delay_50us(uint t)uchar j;for(;t0;t-)for(j=19;j0;j-);void delay(int ms)while(ms-)uchar i
