通过51看门狗定时器的使用，了解看门狗定时器的功能(Through the use of the watchdog timer 51, ​ ​ the Watchdog Timer function )

c8051f060定时器0，系统时钟，交叉开关IO配置(C8051F060 timer 0, the system clock, switch IO configuration)

STM32F103 UART配置，实现C语言printf功能(STM32F103 UART configuration, implement the C language printf function)

DAC5615的使用，能够控制输出电压为设定电压，并保持恒定。(DAC5615 used to control the output voltage setting voltage, and constant.)

超声波跟踪原理及舵机自动实验，有触发信号和接收信号(Ultrasonic automatic tracking principle and steering gear experiment, a trigger signal and the received signal)

说明：  基于STM32F103单片机的PWM测试源码(PWM test source code based on STM32F103 MCU)

51单片机发送，三星的S3C2440接收，并点亮led小灯，通信波特率是115200，单片机采用定时器2来实现该波特率(51 SCM to send, samsung s S3C2440 receiving, and lit led lights, communication baud rate is 115200, microcontroller timer to achieve this by 2 baud rate )

hantek3064仪表上位机监控的示例程序，仅供大家参考(hantek3064 Meter PC monitoring sample program, only for your reference)

说明：  主控采用stm32f407，温度传感器用pt100，可以实现从0到400度的温度采集。并且是双路温度采集。非常精准。(The main control adopts stm32f407 and the temperature sensor uses pt100, which can realize the temperature collection from 0 to 400 degrees. And it is a dual-channel temperature collection. Very precise.)

ISIS实现仿真MSP430单片机开发，有MSP430SRVPAK++7.5补丁和测试程序仿真图(ISIS achieve simulation MSP430 development, and testing procedures have MSP430SRVPAK++7.5 patch simulation diagram)
