基于MSP430F13X系列16位单片机，实现的软件IO方式模拟I2C协议的C源码，已编译通过，并经过实际测试。希望对各位做嵌入式开发的朋友有所帮助。...

这个源码是在电源上电过程中的处理程序，在单片机上电过程中需要有很多步骤去处理，供大家参考讨论-This source code is in the power supply in the course of treatment procedures, the single-chip power and the need to have a lot of steps to deal with, for reference to discuss

[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
