说明：  STM32CUBE软件使用教程1----流水灯用软件怎么设置？ 貌似默认的教程都是从流水灯开始的，呵呵 用这个软件编写arm的流水灯只需要三行代码 下面就一步一步来，大部分时间都是鼠标点点就行了。
(STM32CUBE software tutorials 1---- water lights software how to set? Looks like the default tutorials are from the beginning of the light water, huh With this software development arm of the light water need only three lines of code Here s a step by step, little mouse most of the time on the line.)
