AT89C51-DPSK

电力电子中高压直流输电控制系统的12脉波驱动仿真模型(power hvdc 12pulse)

一个用430单片机设计的温控仪表电路图方案。采用protelse99设计的，里面只有电路图、没有pcb图。(A single chip with a 430 temperature controller circuit design program. Designed by protelse99, only the circuit, no pcb diagram.)

这是个用矩阵键盘控制步进电机圈数和转速的程序，参数设定在触摸屏上显示(This is a matrix keyboard to control the stepper motor number of turns and speed program parameter settings on the touch screen display)

说明：  对lcd1602屏的一些常见问题作出解释，并附上一段51单片机驱动lcd1602代码(Explain some common problems of LCD 1602 screen, and attach a section of LCD 1602 code driven by 51 single chip computer.)

说明：  32F1串口频率计，1--10M（仪器原因更高未测），串口输出(32F1 Serial Port Frequency Meter)

AD9833的编程方法，通过设置一定的参数，可得到DDS(AD9833 programming method, by setting certain parameters, obtained DDS)

一个倒车雷达的程序 使用的是AVR单片机。 在include.h文件里面定义 #define CPU_F 4 //4MHZ 定义外晶振的频率 #define GOOD //40KHZ更准确 #define DIS150CM //若定义了，1.5M有效，没有定义就是2.5M有效 #define DEBUG //若定义了，则是调试模式debug , 没定义就是release模式 (Include.h document in which the definition of# define CPU_F 4// 4MHZ definition of the frequency of oscillator# define GOOD// 40KHZ more accurate# define DIS150CM// if defined, 1.5M effective, efficient 2.5M is not defined# define DEBUG// If defined, it is debug mode debug, not release model is defined as)

Abstract—This paper describes a new approach for a course and laboratory designed to allow students to develop low-cost prototypes of robotic and other embedded devices that feature Internet connectivity, I/O, networking, a real-time operating system (RTOS), and object-oriented C/C++.
