[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

这是微软的一个USB块传输例程，虽然它是基于Intel USB开发板的，但是也很值得我们好好的研究。-This is a Microsoft USB block transmission routines, although it is based on the Intel USB development board, but also worthy of our good look.
