【MM32F5270开发板试用】一、基于MindSDK的电能监测

一项目简介

本次测评基于实际项目需求，主要实现设备的本地控制，电能监测，设备状态在线监测等基本功能，所有采集信息在触摸屏上显示。目前主要实现电能监测功能的实现，将测量结果显示到陶晶驰串口屏上。

二模块介绍

1 陶晶驰串口屏
串口屏：用于简化屏幕开发的一个集成度比较高的屏幕，一般屏幕上集合了运算能力比较强的单片机，用于独立处理屏幕事件与通讯。通过串口协议与其他主控板进行通讯，从而对屏幕进行交互控制，搭配一个pc端图形化开发界面，用于降低开发难度。

2电能计量模块
单相交直流自适应电能计量模块IM1266，是深圳艾锐达光电有限公司为产品用电情况监控而研发的模块。可测量电压，电流，功率，功率因数，频率等电气数据，通过串口与单片机通讯，实现自动化数据采集及监控功能。

串口读取IM1266参数指令

void do_IM1266(){  
  
    uint8_t hostSend_IM1266[8]={0x01,0x03,0x00,0x48,0x00,  
                                0x08,0xc4,0x1a};  
//发送读数据指令  
   for(uint8_t i=0;i<8;i++)  
   {  
     app_uart_putchar(hostSend_IM1266[i]);  
   }  
}
