在端口PD输出PWM脉冲
- 在端口PD输出PWM脉冲,可用示波器测量,或者外加一LED灯,可以看到LED脉宽的变化-PD PWM pulse output port can be used oscilloscope or plus an LED light, you can see the LED pulse width changes
PWM_Output_Input
- 用TIM3定时器在PA6、PA7、PB0、PB1输出四种频率相同占空比分别是50 、37.5 、25 、12.5 的信号。 用TIM2的PWM_Input功能,从PA1口捕获PWM信号的频率及占空比,并用USART1输出测量信息。-At TIM3 timer with PA6, PA7, PB0, PB1 output frequency of the same four are 50 duty cycle, respectively, 37.5 , 25 , 12.5 of the
