keil和Proteus联调所必须的一个文件，看到好多网友都在找，所以传上来，希望对大家有用-keil and Proteus FBI needed a file, see a lot of users are looking for, so Chuan-up, in the hope that useful to everybody

A complete collection of a simple alarm clock with minimum compenents used and simulation in proteus The hardware is complete and practically implemented with 100 success.-A complete collection of a simple alarm clock with minimum compenents used and simulation in proteus The hardware is complete and practically implemented with 100 success.

移植好的stm32f207+ucosIII+lwip版本。ucosIII是ucos的最新版本。lwip已经更新到了最新的版本。系统可以运行，大家可以试一下。

这个源码是2014年电子设计大赛湖北赛区的B题，金属探测器。包括金属探测器的驱动，还有金属探测器的扫描方式，以及确定圆心的算法。当时我们用的是皮带传动，x，y轴扫描方式，效果非常好，就是100%中圆心，不管是硬币还是铁环。
