FTM S32k144 indepentent PWM channel

lohrsistemas — Mon, 20 Aug 2018 11:55:33 GMT

Dear Team,

How do I configure the module FMT1 channel 4 as a simple PWM, independent channel, 200 Hz, without using Processor Expert?
I'll have to update the duty amount on my main loop.

Does anyone have an example?

Hi,

Please take a look at the attached simple example.

The duty cycle and period of a left-aligned PWM is being continuously updated from the main loop using software triggers.

Regards,

Daniel

Hi Daniel,

I would like to know about the possibility of modulating on FTM2 & I'd raised few issues on using

SIM->FTMOPT1=SIM_FTMOPT1_FTM3_OUTSEL(0x01); how does this help in modulation and what is its significance?

Similar thing I asked a question in FTM2 Output Modulation.

Kindly suggest to us in this regard.
