STM32F4 C++ 封装库 之 EXTI
这几天看了下 mbed 的源码，给上层应用调用的接口封装的还是不错的。代码质量比较高，注释也很详细，文档和例程比较全。但是驱动层的程序全是 c 语言编写的，代码质量就没有那么高了，注释比较少而且不规范，比较怀疑 mbed 的稳定性。mbed 的实时内核是用的 rtx5 ，文件系统用的 fatfs ，还有一些开源的协议栈，整套系统比较繁杂。mbed 框架是为物联网设备开发的，工业控制级别的产品可以考虑用 rte 框架。rte 框架目前驱动层程序还不太完善，有好多需要自己去实现，可能在过一段时间会好一些吧。总之物联网产品可以用 mbed ，工业控制产品可以用 rte 。这几天封装了 exti ，距离整套系统可以产生生产力还有很长的距离要走，我也不知道整个系统会成什么样子，我能坚持多久，不管了先做再说。在这里分享我的 stm32f4 c++ 封装之旅。今天分享《stm32f4 c++ 封装库 之 exti》，直接上代码了~
