基于F28335的SCI串口通信程序。本程序的特点是代码简单、高效。本代码共包含三个工程文件：1、基本通信（实现了最基本的通过SCI协议通讯的功能。上位机下发一个字符或字符串，下位机原样返回该字符或字符串）；2、SCI通信FIFO版（在1的基础之上启用了FIFO缓存接收或发送的数据）；3、SCI通信FIFO与中断版（通过启用FIFO功能减少对CPU资源的占用，且数据的发送与接收处理均在中断中完成）。此三个程序基本验证了F28335的SCI模块所有功能。-F28335 of SCI-based serial communication program. Features of this program is the code simple and efficient. This code contains a total of three project files: 1, the basic communication (via SCI achieve the most basic functions of communication protocols issued the PC or a character string as the next crew to return to the character or string.)　2, SCI communication FIFO version (on the basis of a FIFO buffer above the receive or transmit data enabled)　3, SCI communication FIFO and interrupt version (FIFO function by enabling reduce the occupancy of CPU resources, and sending and receiving data are processed in interrupt completed). The three basic procedures to verify the F28335 all functions of SCI module.
