说明：  STM32控制AD9954产生正弦波等波形，频率幅值可调，各种调制。(STM32 controls AD9954 to generate sinusoidal wave, frequency amplitude adjustable, various modulation.)

本实验利用STM32F407开发板连接TFTLCD模块，实现TFTLCD模块的显示，下载成功后，通过把LCD模块插入TFTLCD模块接口，按下复位之后，就可以看到LCD模块不停的显示一些信息并不断切换底色。同时该实验会显示LCD驱动器的ID，并且会在串口打印（按复位一次，打印一次）。(This experiment uses STM32F407 development board to connect TFTLCD module to realize the display of TFTLCD module. After downloading successfully, by inserting the LCD module into the interface of TFTLCD module, after pressing reset, we can see that the LCD module keeps displaying some information and changing the background color. At the same time, the experiment will display the ID of the LCD driver and print it on the serial port (press reset once, print once).)

说明：  基于stm32单片机电压表设计,AD检测分压电阻电压值，根据电阻分压比算出所测电压，并显示在oled液晶上(Based on the design of voltage meter of STM32 single chip computer, AD detects the voltage value of dividing resistor, calculates the measured voltage according to the ratio of dividing resistor voltage, and displays it on OLED liquid crystal.)

这是基于开发板LPC1114的源码程序，是用C语言编写，用于实现系统定时器的配置同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is a source code program based on the development board LPC1114. It is written in C language. It is used to realize the configuration of the system timer. At the same time, it is also a complete template. On this basis, other programs can be added for the learning of the development board. It is a complete template and can be used directly.)

用于描述地下水动力模拟计算，和水体压力，该代码简单容易看明白(water calculator)
