液晶加上触摸使用注意

//按键图片大小 96*40  两按键上下空了四个象素
//写入图片子程序 write_picture(width,high)图片宽与高  先设置好图片的起始位置
//自建汉字库，   print_chinese(qm,wm);参数，机内码
//图片模式清除   lcd_clr(width,high) 宽与高
//设定lcd光标    setxy(uchar lcd_x,lcd_y) +加欲向1335写数据指令
//在固定位置写入按键图片      aj_X()
//在固定位置写入按键反白图片  aj_Xf()
//显示20个按键               print_aj()
//写入图片1      print_picture1();
//在LCD上画一个点    print_din(uint x,uchar y)  320*240任意一点
//画一条直线，指定起点终点   print_line()//cha＝1为写  cha＝0为清除
//画圆  print_round(uint Ox,uchar Oy,uchar Rx,bit cha)//cha＝1为写  cha＝0为清除
//请求与主机通信   tell_zj()
//的在设定的按钮之外会返回AJZ = 255
