基于51单片机的dac0832设计，含proteus仿真，用keilC编译的，代码详细，含有注释，望点个赞，谢谢，头文件全，方便移植。(Dac0832 51 microcontroller-based design, with proteus simulation, using keilC compiled code in detail, contains notes, looking like a point, thank you, header files full, easy to transplant.)

rx8025 日历时钟芯片程序，该程序广泛的被移植到实际产品中(rx8025 calendar clock chip program, the program has been ported to a wide range of practical products)

MSP430G2553串口工程代码 已经调试成功(MSP430G2553 serial debugging code has been successfully engineering)

lsm6Ds3的硬件IIC驱动程序，读取角速度及加速度，设置LSM中断。(The hardware IIC driver of lsm6Ds3 reads the angular velocity and acceleration and sets the LSM interrupt.)

说明：  这是基于STM32和FPGA的简易数字存储示波器(This is Simple Digital Storage Oscilloscope Based on STM32 and FPGA)

实现简单自动售货机的基本功能。投币找零功能，并用Led数码管显示，输出结果用Led显示。(Basic functions simple vending machines. Coin change for function and use Led digital tube display, the output display Led.)

说明：  只做了时间显示，和温度显示，使用一个按键切换(Only time display, and temperature display, using a button to switch)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

基于STM32F103R8的PID算法例程，PWM输出控制信号，ADC输入反馈信号，形成闭环控制，完整工程源码。(PID algorithm based STM32F103R8 routines, complete engineering source, PWM output control signal, ADC input feedback signal to form a closed-loop control.)
