可靠的串口stm32串口程序，注意，这不是简单的例程，而是具有实用价值的程序，将printf函数进行了重载，并且不会造成内存泄露，另外还有一个完全自己写的printf函数，两个函数都可以使用，至于选择哪个程序用，则是仁者见仁智者见智的事了。

前言想了很久,要不要写这篇文章?最后觉得对操作系统感兴趣的人还是很多,写吧.我不一定能造出玉,但我可以抛出砖.包括我在内的很多人都对51使用操作系统呈悲观态度,因为51的片上资源太少.但对于很多要求不高的系统来说,使用操作系统可以使代码变得更直观,易于维护,所以在51上仍有操作系统的生存机会.流行的uCos,Tiny51等,其实都不适合在2051这样的片子上用,占资源较多,唯有自已动手,以不变应万变,才能让51也有操作系统可用.这篇贴子的目的,是教会大家如何现场写一个OS,而不是给大家提供一个OS版本.提供的所有代码,也都是示例代码,所以不要因为它没什么功能就说LAJI之类的话.如果把功能写全了,一来估计你也不想看了,二来也失去灵活性没有价值了.下面的贴一个示例出来,可以清楚的看到,OS本身只有不到10行源代码,编译后的目标代码60字节,任务切换消耗为20个机器周期.相比之下,KEIL内嵌的TINY51目标代码为800字节,切换消耗100~700周期.唯一不足之处是,每个任务要占用掉十几字节的堆栈,所以任务数不能太多,用在128B内存的51里有点难度,但对于52来说问题不大.这套代码在36M主频的STC12C4052上实测,切换任务仅需2uS.
