本文讲述AVR定时/计数器0的各种使用，包括各个寄存器的使用方法、电路、波形，并给出了几个不同的程序，有计数实验、定时实验、比较匹配实验、快速PWM实验、相位修正PWM实验。-This article describes the AVR timer/counter of a variety of uses, including the use of various registers, circuit, waveform, and gives a few different programs,

基于STM32的双相四线步进电机控制，操作简单 可能库文件名称不相符-Based on the the STM32 dual-phase four-wire stepper motor control, operation simple and may be the name of the library file does not match

使用keil5编写的STM32输出四路互补的PWM，适配正点原子的mini版，同样是为电赛逆变系统做的准备。通过定时器的输出比较模式，在PC6~PC9，输出4路PWM，每路PWM频率为500Hz，占空比为50%，每一路PWM相位差为45°(The STM32 output four complementary PWM, which is written in keil5, is suitable for the mini version of the positive point atom, w
