一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定(A more typical PID treatment procedures, the use of single-chip microcomputer as the control cpu, please make some simplification, the specific PID parameters must be determined through experiments at specific audiences)

pwm方波控制仿真 通过仿真输出方波pwm 并输出正弦波 谢谢(PWM square wave control simulation by simulation output square wave and sine wave output for PWM)

STM8的IIC程序 用库函数操作，上手容易。(STM8 the IIC program)

说明：  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)
