FM17522LPCD官方例程FM17522LPCD详细说明,次要包含了寄存器的说明及使用流程.

天线电感选择比TVDD发射电流大的标称值，封装选择尽量小，但不能0805小。
如FM17550，天线发射电流在100mA，可以选择MLF2012DR68KT,680nH,±10%，该电感电流达到150mA。
如使用RC663，电感选择需要比250mA标称值大。
天线采用双端驱动，具有更好的驱动能力。
对应天线区域内的元件，选择5%精度以内的，在使用低功耗侦测卡片（LPCD）功能时，天线区域内元件选择2%精度以内的。
精度10%的元件会导致天线谐振频点偏差，如天线谐振电容在200pF,误差在±20pF,会使得谐振频率偏离±0.6MHz,导致读卡功能严重下降。
在使用LPCD功能时，元件误差会导致误触发读卡或者卡片侦测不到，产品一致性难以保证。

（含源码及报告）本程序分析了自2016年到2021年（外加）每年我国原油加工的产量，并且分析了2020年全国各地区原油加工量等，含饼状图，柱状图，折线图，数据在地图上显示。
运转本程序需要requests、bs4、csv、pandas、matplotlib、pyecharts库的支持，如果缺少某库请自行安装后再运转。
文件含6个excel表，若干个csv文件以及一个名字为render的html文件（需要用浏览器打开），直观的数据处理部分是图片以及html文件，可在地图中显示，数据处理的是excel文件。
不懂可以扫文件中二维码在QQ里面问。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
