LM3S_UART
- 《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
rs485
- 操作串口直接进行RS485多机通信的类。单片机下485多机通信很容易,用UART的Bit9即可,Windows下就麻烦得多,Windows下串口Bit9用作奇偶校验,要切换Bit9就要动态改通信格式,而且切换时间要跟得上单片机的us级时间。这个自己写的Class用独立线程、Windows高精度定时器机制,高速切换Bit9,示波器测量,时间在10us左右,已用于门禁系统多年,长时间运行可靠! -Direct RS485 serial port operation multi-machine c
