编写适用于STM32的ISP下载器程序.doc

前一阵公司外购了一些控制器，配合公司的开关一起发给用户。发货前领导认为控制器开机界面会出现我们进货厂家的LOGO不好，应该改成我们公司的名称。于是与控制器厂家协调，让他们把开机欢迎界面改动一下。没几天对方发过来一个ISP下载器，我们用它把控制器的程序升级了一下，就改过来了。
    闲来无事，感觉这个ISP下载器很有意思。之前我们升级程序，因为还没有着手开发远程自动升级功能，必须到现场去升级。而且用的STM32F103的处理器本身不具备作为主机使用USB的功能，升级的时候使用串口。所以当设备安装在现场的话，就需要带着笔记本，USB转串口线去现场，比较麻烦。而且，笔记本一来体积大，本来出去带着工具什么的东西就很麻烦，再带着本就更头疼；二来在现场也不好用，有转接口不好使的问题，也有其它原因，比如可能需要爬杆，在几米高的杆上抱着本给设备升级是很恐怖的事情。鉴于此，感觉这个ISP下载器还是比较好的一款东西。当然，对方厂家给我们发过来的这款下载器是针对他们用的处理器的，跟我们的不合适。在网上搜索一番，发现还真能找到STM系列的ISP下载器，价格在1200元左右。比起笔记本来说倒是很合算。准备买它几个。
    当然准备买，那是领导的打算。我觉得应该可以自己做一下，反正我也有不少空闲时间。于是便行动起来。
    首先，我先在网上找了一款免费的串口监听工具“串口监控精灵”下载安装好。然后将我们的控制器与PC用串口连接好。打开监控精灵，然后打开“串口调试助手”，向终端发送命令。发现监控精灵可以很好的将串口间的上下通信显示出来，并且会给出对串口进行配置的显示。这样，在ISP模式下给控制器上电，在PC上打开STM的flashloader，配置好，下发一个源程序，分析监控精灵的数据：
