据三维Hashin失效准则和Chang-Chang退化准则

stm32与fpga进行spi通信，fpga进行测频，占空比，时间间隔测量，32可控制其运行模式，并将测得结果于lcd上进行显示。(STM32 communicates with FPGA in spi. FPGA measures frequency, duty cycle and time interval. 32 can control its operation mode, and display the measured results on lcd)

12864液晶显示，运行环境是AVR单片机。文件问一个工程，可行。(12864 LCD, the AVR microcontroller operating environment. File ask a project feasible.)

时钟功能，调整时间与设定闹钟此两种功能，一键多义功能按键，实现时钟跟闹钟的输出显示(Clock function, adjust the time and set the alarm these two functions, one-touch function keys polysemy to achieve the output of the clock with the clock display)

说明：  这是一款数字电压表，ad转换之后显示出来，一个简单的例程(For robots, most of the information is obtained from visual sensors and tactile sensors (including slide tactile sensor). The visibility in the seawater of China is very low except Nanhai. Even in the water of high visibility, the water will be turbid and the visibility will become very low when the robot is working.)

msp430f149三相逆变电源源代码，可以输出6路spwm信号(msp430f149 spwm)

说明：  蓝桥杯CT107D矩阵键盘的源代码测试使用供学习和参考(Blue Bridge Cup Matrix Keyboard)

说明：  基于zigbee开发 CC2530的直流电机控制(Development of DC Motor Control Based on Zigbee CC2530)

说明：  它是关于80C51单片机的原理介绍和使用其开发的过程，有具体的实例。(It was introduced on the 80C51 microcontroller and use the principle of its development process, with specific examples.)

基于PSIM的48-24VBUCK电路仿真，PID调节控制(Based 48-24VBUCK circuit simulation PSIM is, PID control adjustment)

利用4*4矩阵键盘控制C8051f040片内DCA输出，利用LCD1602显示输入的数字量，输出范围0-5V，DAC精度12位。(Use 4* 4 matrix keyboard control C8051f040 DCA chip output, use LCD1602 display digital inputs, output range 0-5V, DAC precision 12.)
