這幾天精神狀態不佳，今天才出成果，LCD1602 顯示，由于使用的是字符型的LCD，所以無法顯示漢字，只能是字符，好了，代碼來襲~~
#include<reg52.h>
#define uchar unsigned char
#define uint unsigned int
sbit LCDE=P2^7;
sbit RS=P2^6;
sbit RW=P2^5;
uchar code table1[]="x=1,y=1"; //顯示第一行內容
uchar code table2[]="x=2,y=2"; //顯示第二行內容
void LCD_write_com(uchar com); //寫指令
