1、IAP15F2K61S2液晶1602显示#include stc15f2k60s2.h int i; sbit rw=P36; /1602 IO口定义 这里用的数据口是P0口 sbit rs=P35; sbit ep=P37; unsigned char code d = stc15f2k60s2; unsigned char code a = /汉字 0x04,0x0f,0x09,0x0f,0x08,0x0f,0x15,0x07 , /启 0x04,0x15,0x0e,0x1f,0x04,0x05,0x0b,0x13, /光 0x04,0x1f,0x15,0x1f,0x15,0x1f,0x0
