EX4

说明：  PADS软件打开，一个DDR，需要的可以下载参考(PADS software open, a DDR, you need to download reference)

说明：  基于PO算法计算仿真单反射面天线的方向图(Computation of Antenna Patterns of Simulated Reflector antennas Based on PO Algorithms)

STM32的IAP升级程序，已经是可以用的，是用SD卡升级的程序，简单好用，有需要的朋友可以直接用(The STM32 IAP upgrade process, it is already possible to use, is to use the SD card upgrade program, easy to use, a friend in need can be directly used)

5G C-RAN master code (cloud radio access network )

说明：  利用python+opencv测量图片中目标物体之间的距离(Measuring distance between objects in an image with OpenCV)

一个非常值得研究的源代码，界面和功能几乎和windows自带的扫雷游戏一模一样，可以设置游戏难度等级，值得学习。-a very worthwhile study the source code, interface and functions almost windows own mine same game, the game can set the difficulty level, it is worth learning.

基于stm32开发板的简单应用，LED闪烁，跑马灯及蜂鸣器的应用。(Based on the simple application of STM32 development board, the application of LED scintillation, horse-running lamp and buzzer.)

说明：  这是一款非常实用的计算器,我认为其实用程度远远胜过Windows系统提供的计算器.主要特色是支持多项式运算,即可以一次输入整个多项式,并能够识别运算的优先级(利用堆栈实现)(This is a very practical calculator, I think far better than using Windows systems calculator. The main feature of polynomial Operational support, which can import an entire polynomials, and to identify the priority level computing (using stack realization))
