该系统硬件电路简单稳定，可靠性较高；该系统由阻容降压供电电路，电压测量电路，电流测量电路，显示电路等部分组成。

电压测量部分是220v电压经过变压器降压后经过整流桥得到1.7v半波电压，输入单片机之后经采样和数据处理，可得到电压的峰值，周期，频率，有效值等参数；电流参数测量电路是采用了50A/62.5mA互感器将负载上的大电流转换成较小的电流，并将小电流通过定值电阻，电阻两端的电压输入单片机从而计算得到电流峰值，有效值等参数；采用的是全球鹰SIM900A V3.7模块，固定时间给用户发送短信，让用户了解目前耗电情况。

题目中要求的参数均经单片机计算输出到OLED液晶屏模块上予以显示。

关键词：MSP430F149 低功耗 ADC采样SIM900A V3.7模块1目的与内容随着国民经济的不断发展,电力已经成为国家的最重要能源。

长期以来,我国生产的交流电度表均为感应式机械电度表,几十年来不得不采用人工抄读电表的原始方式。

这种方法不但劳动强度大、效率低,而且还会存在抄表不到位、估抄、漏抄、错抄、错算及抄表周期长等问题,对窃电的防治更无从谈起。

MSP430F149单片机BSL编程说明1、安装USB驱动程序首先安装USB驱动程序，安装完成后在Windows的设备管理器中查看串口序号。

2、在BSL编程软件中选择串口，并做相应设置按照串口序号，选择COM3，BSL编程软1贴图如下：BSL编程软2贴图如下：（先点击“SETUP”设置，然后，点击“AUTO”编程）3、用IAR编译器生成TI-TXT编程文件TI－TXT文件是TI公司为MSP430单片机定义的一种编程代码格式，其内容为纯文本格式，使用任何文本编辑器都能对其进行阅读，可按照以下方式生成TI－TXT文件： 打开一个工程之后，点击菜单Project>Options..>Linker>Output>Format>Other>Output 一栏中选择“Msp430-txt”即可，重新编译后生成的txt文件将出现在你的工程路径下的\debug\exe或者\release\exe 目录下。

4、BSL编程跳线连接方法BSL编程的时候，把J4的1-3、2-4用跳线短接，把J3的3-5、4-6用跳线短接，参见下图，然后用USB线和PC机连接好，打开上位机编程软件，参见第二步“在BSL编程软件中选择串口，并做相应设置”，点击相应的按钮，即可进行相应的操作。

注意，如果使用串口通信，要把J4的1-3、2-4上的跳线断开，并把J3的1-3、2-4用跳线短接，即可实现和PC机的串行通信。

其他相关知识点1、JTAG、BSL、熔丝JTAG接口能够访问MSP430单片机内部所有资源，通过JTAG 可以对芯片进行程序下载、代码调试、内存修改等等，通过JTAG还能烧断加密熔丝，熔丝一旦被烧断，JTAG接口绝大部分功能失效，就再也不能通过它进行编程了。

2、BSL接口的功能BSL接口是利用芯片内部驻留的bootloader 程序实现的自编程，通过特定的时序使得CPU 进入bootloader代码断，然后利用每个MSP430芯片内部都有的Timer_A构成一个软件串口来与上位机通讯，这样可以将代码下载到芯片内部。

MSP430F149的串口RS232接口1、概述具有同步串口模式（SPI）,异步通信模式（UART）。

作异步通信时,P3.4，P3.5，P3.6，P3.7第二功能分别是UTXD0, URXD0, UTXD1, UTXD2 2、使用方法概述2.1 程序架构配置寄存器设置工作模式{设置IO口为第二功能作为串口收发引脚；使能串口收发功能；选择每帧数据位为7或8；选择波特率发生器时钟源；配置波特率（查表得出值再配置UxBR0, UxBR1，UxMCTL）;软件清除串口复位位（SWRST）；若采用中断方式则使能接受、发送中断}编写接受/发送程序，可采用查询方式或中断方式。

同51单片机不同的是，UTXIFG,URXIF 在发送下一个数据和读取数据时被自动清零了，无需软件清除。

2.2 细节描述配置波特率时用户手册上有速查表，如下设置波特率时要选择合适的时钟源。

对于较低的波特率（9600b/s及以下），可选ACLK,大于9600要选用SMCLK,因为串口波特率发生器分频系数要求大于3。

UxBR0（低）UxBR1（高）值的计算式为：选择的时钟源/波特率，再取整。

为了精确，MSP430设置了小数分频功能，通过UxMCTL来完成。

430F149最小系统板结构图
最小系统图：
MSP430F149引脚图：
1、左上角+5V用来给最小系统供电；本模块提供两组+5V，目的是
用户外设供电可以从这里引出。

左边排针比右边多一组，一方面可以从底板引电源，另一方面为了便于区分，可以防止插反。

2、J3（VCC SEL）用来选择JTAG引脚的第2脚电源，短接J3，表示从系统板引电源，拔掉跳线J3，从计算机并口或USB口引电源。

有些计算机的并口不能提供可靠的电源，因此需要短接J3。

3、JP1、JP2为MSP430F149所有引脚说明，做外设连接的时候，可以参考上面MSP430F149芯片管脚图与系统板结构图。

单片机学习心得体会单片机学习心得体会12篇当我们受到启发，对生活有了新的感悟时，可以通过写心得体会的方式将其记录下来，这么做能够提升我们的书面表达能力。

相信许多人会觉得心得体会很难写吧，下面是店铺整理的单片机学习心得体会，欢迎大家分享。

单片机学习心得体会1做了两周的课程设计，有很多的心得体会，有关于单片机方面的，更多的是关于人与人之间关系方面的。

我们组一共有三个人，但其他两个人是真的神龙见首不见尾，除了在最终答辩的时候他们一齐坐在了我旁边，冠冕堂皇的指着我画了几遍的图说了几嘴，我想可能他们自我都不明白自我在说怎样，虽然有的东西他们也答出来了。

我佩服他们的勇气，羡慕他们的运气（我见到的很多做了10天的人最终的成绩都有不如他们的），可是鄙视他们的做法。

所幸的'是，我得到了很多同学的帮忙。

我想没有他们我可能都要放弃了，因为我本人对单片机也并不是很熟悉，学的东西好像它是它，我是我似的，理论联系不了实际。

以前的汇编语言没学好，一开始的程序这块儿就要令我抓狂了。

之后请教我们班的一个男生，每次跟他一齐到试验室调试程序（他们组也仅有他一个人动手），看他边做边给我讲解。

最终在开发机上做出来的时候，虽然不是我自我写的，但看他那么高兴，我也有一种分享到的成就感。

之后我们组就用了他写的程序，他自我又抽空做了些拓展。

接下来就是做硬件方面的焊接工作了。

没想到这项看起来不需要多少技术的工作却是十分的劳心劳力。

很多次是早上起来带瓶水带些吃的到实训中心，一泡就是一天。

我看到有很多人跟我一样，不一样的是他们是三三两两，而我大部分时间都是一个人做。

在这个时候也有很多人帮忙我，或是热心的帮我带饭，或是在我打盹儿的时候帮我做点焊接。

大家都鼓励我，即使最终出不来东西，可是必须要坚持把它做完。

当我想放弃的时候，我也这么对自我说，即使你做出来的是次品甚至不合格品，可是你必须要拿出来一件成品。

在要验收前，最终做了一件成品出来，不幸的是它真的是一件不合格品。
