Hello Community, I am trying to change the duty cycle of a PWM Signal.. I went through a few examples and the AN5303 document with examples code.
Line 3:调用LPLD_FTM_PWM_ChangeDuty()函数来改变CH0通道的占空比,该函数和PWM通道使能函数的个别参数一样,使用时最好先参考在线函数手册。输入捕获功能IC工作原理IC就是Input Capture的英文缩写,即输入捕获。很多新手不仅疑惑FTM,还疑惑他怎么还有这么多功能,更疑惑这么多功能中输入捕获到底干什么用。首先FTM为什么...
LPLD_FTM_PWM_ChangeDuty(FTM0, FTM_Ch0, angle_to_period(45)); Line 1:在初始化完毕后,首先应该延时一段时间,以保证舵机可以有足够的时间归位。 Line 3:调用LPLD_FTM_PWM_ChangeDuty()函数来改变CH0通道的占空比,该函数和PWM通道使能函数的个别参数一样,使用时最好先参考在线函数手册。 输入捕获功能 IC...
FTM_PWM_UPDATE_IN_DUTY_CYCLE为变更类型,这里选择变更占空比; value*327.68, 0U 两个为要改变的占空比,这边将0~0x8000改为0~100%; 调节PWM频率 void FTM3_PWM_Period_Output(int tick) { FTM_DRV_UpdatePwmPeriod(INST_FLEXTIMER_PWM2,FTM_PWM_UPDATE_IN_TICKS,tick,true); } FTM_PWM_UPDATE_IN_TICKS...

Hello, I'm encountering a strange phenomenon while using the FTM_PWM module on the s32k144 microcontroller. I've configured the PWM frequency to 10HZ with the default polarity set to high and an initial duty cycle of 0%. When I dynamically adjust the duty cycle using the FTM_DRV_Update...

51也有这种方式做pwm输出，同样，一个是用定时器0做载频，定时器1做pwm调制，我不知道飞思卡尔单片机有没有专用的pwm口输出，好果没有专用的pwm口输出，那就是我前面说的这样,主要用与调节电机的快慢，
