s32k144

Hi,

I am using s32k144 for my application. I have used FTM0 CH0 and CH1 (100Khz) as Center aligned in Up -Down count mode with complimentary . also I am used FTM3 CH0 as Center aligned in Up -Down count mode but no complimentary .When I have applied fixed duty cycle count.I got correct PWM at FTM0 CH0 and CH1 , but my FTM3 CH0 is shifted by 5usec. I want all PWM channels start at same instant (FTM0 and FTM3 ),So Which setting I have to do in Init for all PWM start at same time.

Also In ADC module I have used one shot ADC convert with SW trigger. I got correct output but with PDB trigger for continues conversion (for more than 1 channels ex. 4 channels) in polling mode no interrupt what settings I have to do it in ADC INIT. Please share example code for same if available.

Hi sagar.yadav@bharatforge.com,
Regarding the FTMn synchronization, please take a look at
AN5303 Features and Operation Modes of FlexTimer Module on S32K

Section 4.4. Global Time Base (GTB).

Have you already seen these ADC PDB examples?
Example S32K144 PDB ADC trigger DMA ISR S32DS

Example S32K144 PDB ADC DMA S32DS.ARM.2018.R1

Thanks,
BR, Daniel

Hi,

Thank you or email,

PWM synchronisation has done. Working well now. ADC I am trying with same example you have suggested to me.

Thanks and Regards,
