是51单片机与台达触摸屏通讯。原因为如果台达触摸屏发一组数据给我，我能正确接收，将收到的数据显示在数码管上，同时我也回复它。用PC可以看出来我回复的内容。触摸屏发一次我回一次-Delta is 51 and touch-screen communication. Because the touch screen as if Delta made a set of data to me, I can correctly received, the data received in the digital tube, and I also back it. PC can be seen with the contents of my reply. I sent back the touch screen once again
