基于LCD1602的人机界面设计

已有 2564 次阅读2010-3-5 16:09 |

 
                                 系统启动界面。
 
                                               RTC 界面
                        设置ID界面
 
 
背景：左边的CPU模拟DSP，右边的CPU模拟EM78P5840。
      DSP扫描按键，（分别是MENU，UP，DOWN，ENTER）
      MENU为显示页面切换。
      ENTER为参数设置按键。
      UP用来增加参数。
      DOWN用来减少参数。
     DSP通过I2C总线传输给MCU，由MCU驱动LCD显示相应界面。

打猎照相机的，当有猎物经过照相机，自动拍照，这只是个人机界面而已。

看到delay( );我就怕。能否把delay( );都减去？

基本不能，这个主要用来保证必要的时序的，否则ＬＣＤ不能显示
