《LM3S系列CPU高性能串口驱动程序》

现在很多ARM7芯片已经使用了Cotex-M3内核，我开始接触这东西是从周立功的LM3S1138开始的。周立功提供的1138串口例程基本不具有实用性……

该驱动程序在利用LM3S系列CPU自身FIFO的同时，利用环形缓冲区构建了软件层的Buffer，采用中断方式进行Buffer读写，效率高，运行稳定，可用于透传、网关等各种大数据流量的场合。程序包含头文件，注释详尽；基于Stellaris外设驱动库编写，方便移植。并支持485通信，串口初始化数据自动解析等功能。-" LM3S series of high-performance CPU serial port driver"　A lot of ARM7 chips have been used Cotex-M3 core, I came into contact with this thing from the ZLG the LM3S1138 began. ZLG provided by the 1138 serial routines do not have the availability of basic ... ... the driver in the use of LM3S series CPU' s own FIFO, while the use of circular buffer to build a software layer Buffer, used to interrupt Buffer read and write, high efficiency, stable operation can be used to pass through, gateways and other large data traffic occasions. Program contains header files, comments, details　Stellaris peripheral driver library based on the preparation, to facilitate migration. And to support the 485 communications, serial port initialization functions such as automatic data analysis.
