如果您希望以微秒为单位设置任务,则可以选择调用`mcpwm_set_duty_in_us()`。可以通过调用`mcpwm_set_duty_type()`来改变PWM占空比的模式(占空比数值对应高还是对应低)。 **mcpwm_set_duty (in_us) ()** //设置占空比 ```c esp_err_t mcpwm_set_duty(mcpwm_unit_t mcpwm_num, mcpwm_timer_t timer_n...
若要更改PWM的占空比,调用`mcpwm_set_duty()`并以%为单位提供占空比的百分数值。如果您希望以微秒为单位设置任务,则可以选择调用`mcpwm_set_duty_in_us()`。可以通过调用`mcpwm_set_duty_type()`来改变PWM占空比的模式(占空比数值对应高还是对应低)。 **mcpwm_set_duty (in_us) ()** //设置占空比 ```c...
