[文件名] Touch.c [功 能] 8051单片机驱动ADS7846/ADS7843芯片 [简 介] ADS7846/7843芯片 适合用在4线制触摸屏，它通过标准SPI协议和CPU通信，操作简单，精度高，当触摸屏被按下时（即有触摸事件发生）则ADS7846向CPU发中断请求，CPU接到请求后，应延时一下再响应其请求，目的是为了消除抖动使得采样更准确。如果一次采样不准确，可以尝试多次采样取最后一次结果为准，目的也是为了消除抖动。-Driver source code of touch-sensitive screen with ADS7846/7843

视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.

通信方式是485方式。通过485来控制一组灯的开关。-485 are way communication. Through 485 to control a group of light switches.

动态接口采用各数码管循环轮流显示的方法，当循环显示频率较高时，利用人眼的暂留特性，看不出闪烁显示现象，这种显示需要一个接口完成字形码的输出（字形选择），另一接口完成各数码管的轮流点亮（数位选择）。 -display
