使用2543和C51单片机进行电压的实时测量

KEIL C51开发，自用程序，完美测试通过，STC8A8K64S4 读取SHT20温湿度 BMP280气压数据，I2C协议，STC8A8K64S4 时钟选22.1184M(STC8A8K64S4 read SHT20 temperature and humidity BMP280 air pressure data, I2C protocol)

CPU于MCU通过串口传输，增加IO辅助，避免漏传数据(CPU to MCU serial transmission through increased IO assistance, to prevent leakage of data transfer)

16位AD转换器mcp3421读写时序例程，c51代码，稍作修改可以移植到其他单片机使用(16-bit AD converter timing mcp3421 to read and write routines with C51.)

stm32双串口实验，调用串口2接受信息然后用串口1转发。主要参考意义在于两个串口的配置。(Stm32 dual serial port experiment, call the serial port 2 to receive information and then use the serial port 1 forward. The main reference is the configuration of the two serial ports.)

合泰芯片BS83C08A单片机触摸按键应用仿真案例( 17/5000 Thai chip BS83C08A touch button case)

利用 D/A 转换的方式对实时时钟进行语音报时，同时显示时间到LCD1602上(The D/A conversion way voice broadcast real-time clock, and time to display on LCD1602)

STC12C5A60S2串口接收程序，可以接收上位机发送的16进制串口数据，在接收到数据以后执行相应的动作(51单片机串口接收程序，通过接收串口16进制编码，执行相应的函数 51单片机串口接收程序，通过接收串口16进制编码，执行相应的函数 51 single-chip serial port to receive the program, through the serial port 16 to receive the code, the implementation of the corresponding function)

stm32F427的程序，此程序是利用STM32F427开发板的智能机器人的控制。包括对机器人的底盘的控制和云台的控制。(Stm32F427 program, this program is the use of STM32F427 development board intelligent robot control. Including the control of the chassis of the robot and the control of the pan/tilt.)

C51单片机，C语言流水灯控制，通过简单的C语言编程，实现C51单片机对流水灯的显示控制，通过延时函数，可对流水灯的显示情况，进行简单的控制

通过按键控制电压输出并显示，使用了AD0808芯片(By controlling the voltage output and displayed key)
