Is it possible to generate different frequency on each channel on same Eioms instance?

[PratikY]

Hello @PetrS ,

I am using the S32K344EVB-Q257 board. Can I generate different frequencies on each channel of the same EMios instant?

Ex : On Emios Instance 1 channel 22 should generate 1000Hz and channel 23 should generate 2000Hz,is it possible?

Hi,

yes, it is possible for mentioned channels.
eMIOS ch22 and ch23 are Type X channels, so having its internal counter. Can be configured for OPWFMB mode, thus can have its own generated PWM freq.

Hi, @PetrS Thanks for the quick response.

I am able to generate different frequency signals at 22 and 23 channels, but I am asking in general, Is it possible to configure different frequencies from any channel from 0 to 23?

Hi,

no, it is not.
See my reply for similar question on https://community.nxp.com/t5/S32K/S32K344-hardware-PWM-frequency/m-p/1401775

Hi @PetrS , Thanks for the reply.

So as per my understanding, I should be able to generate unique frequency on each channel which OPWFMB Mode, which includes following chanells 

Emios 0
CH0,Ch8,Ch16,CH22,CH23, CH1-CH7

Emios 1 and Emios 2
CH0,Ch8,Ch16,CH22,CH23

Is it correct?

[PetrS]

yes, correct,
