首先定义一个普通输出的PWM通道,类型为PWM_FIXED_PERIOD,设置需要的周期 然后定义需要进行偏移的PWM通道,类型为PWM_FIXED_PERIOD_SHIFTED,该通道不需要设置周期,而是将PwmReferenceChannel设置为前面设置的普通通道,然后设置PwmShiftValue为占空比偏移值,在没有选择PwmDutyShiftInTicks为ON时,输入的值为0-0x8000表示偏移为...
true:支持Pwm_SetDutyCycle()。 false:不支持Pwm_SetDutyCycle()。 该函数是PWM常用的函数,用来设置PWM占空比 image PwmSetOutputToIdle 此参数启用/禁用Pwm_SetOutputToIdle。 true:支持Pwm_SetOutputToIdle()。 false:不支持Pwm_SetOutputToIdle()。 该函数将PWM输出设置为Idle状态 PwmSetPeriodAndDuty 该参数...
the common thread is drive circuitry to control the light output. A few applications are as simple as ON and OFF, but the greater number of applications call for dimming the output between zero and 100 percent, often with fine resolution. The designer has two main choices: adjust the LED c...
占空比(Duty Cycle)就是在一个完整的PWM周期中, 高电平脉冲在时间上占的比例, 通常使用一个百分数来表示. 对应的 PWM 等价电压就是供电电压乘以占空比这个百分比. PWM脉冲的宽度由代码控制, 越宽输出的能量就越高, 电机运转就越快. 当直接连接到供电电压上时, 就等价于一个100%占空比的PWM信号. 通过占空比可以...
Period and duty cycle are given in nanoseconds. For example, for a 100 kHz signal with 50% duty cycle: ~# echo 10000 > /sys/class/pwm/pwmchip4/pwm0/period ~# echo 5000 > /sys/class/pwm/pwmchip4/pwm0/duty_cycle To enable the PWM signal: ...

TIM_Period:目标计数值,达到该数值后会重置为TIM_RepetitionCounter设定的值。 TIM_Prescaler:设置为720分频,时钟源发生720个上升沿信号后才计数一次。 TIM_RepetitionCounter:达到目标计数值后,寄存器值自动重装为0 配置OC输出比较 每个定时器都有多个通道,在初始化时需要指明通道、定时器。 其中: ...
