PWM with DMA

adem_marangoz — Mon, 20 Oct 2025 06:09:14 GMT

Hello NXP team,

i am using S32K144 MCU.

I want to use PWM with DMA, but I want to provide the values through an array. Where through a single function call, it takes these values and provides them as output.

Hi@adem_marangoz

I need to spend some time to make a demo like this for your reference.

It's a bit difficult and I need some time.

Hi@adem_marangoz

Sorry for the long waiting.

The demo based on S32K144EVB, the SDK is RTM 4.0.03, IDE is S32 DS V3.4

Each time the trigger is triggered, the values in the pwm_buffer array are sequentially

transferred to the Cnv of the FTM0-ch0 to change the output PWM.
