关于ADE7753的读写问题，编了个程序，却无法显示正确的结果

//程序功能：读取功率并且显示在数码管上。通过串口发送数据
//波特率是9200
/******************************************
程序的问题是：编译无错，但是利用数码管显示的时候显示：05.35，正确值是02.35
在没有负载情况下，应该是显示0000，但是数码管却一直显示05.35，实在找不出错误来
有时间给我看看，这个程序那个地方有错误

AD工作不正常，采集进来是个固定数据，自己查一下
这个我看过了，采集的数据不正确，同时也没有进行初始化，还一些数据的格式设置不正确，正在改，不知道问题出在哪里，就是显示不正确
谢谢回答
你好，今天做ADE7753 看到你的帖子，我也想用单片机控制ADE7753，你能否给我发一份你的电路图?谢谢！
nanshan123456@126.com。不胜感激！
小编，你ADE7753写好了吗?可否发我一份?479948333@qq.com
小编，你ADE7753写好了吗?可否发我一份?903168319@qq.com，我现在也在弄这个，可发现问题，不给VAP通电时有读数，但在VAP端通电之后测电压时一直为0
小编，发一份电路图可否，903168319@qq.com
