【基于KW41Z的智能电力监测仪的设计】第七贴：电力测量仪软件编程既测量仪调试篇

由于本人对于操作系统不太熟悉，处于学习阶段，因此这里直接采用bare-metal程序进行设计。请采用KDS3.2.0软件，按照提示新建一个空的带drivers的工程，然后添加或者修改如下文件即可。串口115200 8N1，显示程序根据自己的需要进行修改，显示屏具体资料可见我的《【基于KW41Z的智能电力监测仪的设计】第六贴：LCD显示设计篇》https://bbs.eeworld.com.cn/thread-545078-1-1.html；为了让大家能有兴趣，先介绍整机调试图，这里调试的是本项目的电力测量仪部分，下一贴就直接交作业了，就BLE 和 IEEE 802.15.4 测量节点通信进行接介绍。

1.电力测量仪调试测量节点初始界面

测量节点二级界面

三级界面（三相不平衡度显示，图中为模拟数据）

2.程序设计电力测量仪采用NXP-KW41Z来驱动ADE7758，ADE7758.h中包含了底层驱动程序，采用的是I/0口模拟SPI协议的写法，主要是为了移植方便。

3.调试感悟经过近一个多月的努力，学习到了很多东西，感觉自己本科四年，硕士三年都白上了。在电子领域，学校教的东西已经无法用落后来形容了，本科阶段教授一些基础性东西，尚可理解，但硕士阶段就真的很不理解了。虽然，电赛也拿了好名次，但当时做的都是模拟电路设计（放大电路设计），可当我接触FPGA，接触arm，接触NXP单片机时，以及高层次嵌入式编程时，真的受到了巨大的打击。且不说，我们能否造出这款单片机，就是好的东西给我用，我都要自学很长时间。我很佩服TI，ADI，NXP等公司，这些公司真的了不起，不仅能设计芯片，还能推出适配与这款芯片的整个开发链工具。对于我个人，通过这个比赛，发现自己什么都不会，什么都不懂，我觉得自己必须要踏实学习了，在工作中学习，不断自学，才能适应这个社会，才能胜任自己的工作，才能养家糊口，生活下去。感谢EEWORLD论坛，nmg管理员和NXP，以及我自己，让我能够在职业生涯开始之时，清醒的认识到未来的坎坷，我将怀着敬畏之心去探索，去适应，奋斗为了明天更美好！好了，侨情的话不多说，直接上视频，晚上照的不清，大家多多见谅。
