＃2016年高质量新标准全面升级！＃

提问者采纳

//void init_cgram()//{//    unsigned char i;// //;设置自定义字符//    WR_COM=0x40;//    for(i=0;i<24;i++)//    {//      WR_DAT=CGRAM_TABLE[i];//    }// for(i=0;i<40;i++)//      delay();//}//void clr_lcd()//{//   WR_COM=0x01;//   delay();//   delay();//}这两个函数定义了，主函数中没有调用!,去掉就可以了！
