Hi,

Yes, the eMIOS module is able to generate PWM signal.

You can refer to AN4830 (https://www.nxp.com/docs/en/application-note/AN4830.pdf) for the simple code.

The same eMIOS example is also available as a demo within S32DS. It shows how to configure and use eMIOS in

 MCB, OPWMB, OPWFMB, IPM, IPWM modes.

Hi!

   Thanks for your help!

   I read the content of the AN4830, I want to design a breathing lamp with the OPWMB mode.

and there are two problems:

   First,the step of update the A1 register value,also  the duty cycle.

   Another,the relationship between MCB mode and OPWMB mode.

Wait for your reply.

Best regards!
