使用蓝牙芯片来做低功耗开发的时候，需要准确测试出芯片的功耗情况，担心手册上的功耗描述和实际不符合，可以基于厂家自带的例程来测试功耗，本文指导如何测试沁恒 CH582M 开发板的功耗情况。

软件：

集成开发环境(IDE)：http://www.mounriver.com/

沁恒蓝牙开发https://www.wch.cn/products/CH583.html

硬件：沁恒开发板、BRD4002A、PC、USB转串口工具

1、下载沁恒开发资料后，在EVT\EXAM\PM目录下找到PM.wvproj文件使用MounRiver Studio打开。

2、编译工程会在目录obj\StdPeriphDriver下生成PM.hex文件。

3、打开WCHISPStudio烧录软件，选择好自己芯片型号，使用USB口烧录口烧录程序（烧录程序是需要把PB22接口接地，然后板子上电就能识别到设备了）。

4、开发板烧录程序之后，连接上USB转串口工具，查看开发板打印状态和功耗情况。

5、通过PA5口控制开发板处于不同的功耗模式。

【经验】将沁恒微CH582M开发板的下载配置脚修改为PB11后无法再进行烧录的解决方法

在使用沁恒微CH582M开发板进行调试时，如果项目中需要用到两路串口，这时就需要使用到CH582M的PB22引脚作为串口的RX来使用，需要将下载配置脚修改为PB11，不少开发者在将下载配置脚修改为PB11后，板子的USB接口就无法被识别到从而无法烧录程序。
