cc2530uart1串口初始化，并且通过串口中断接收，cc2530uart1串口初始化，并且通过串口中断接收

本代码（工程文件，可直接编译、烧写）基于stm32F103ZET6，开通串口2（uart2，使用正点原子的精英板V3，PA2/PA3两个串口均可正常工作，PA2/PA3在板子上没有集成串口调试硬件，在进行电脑调试时请使用PA9/PA10的进行验证或另配硬件）。
正常情况下网络上例程均只有一个串口被打开（即uart1），使用者在移植时只需要把uart2头文件与源文件add进自己的文件夹即可。

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。
