I want to receive can data and export pwm based on that data.

How can i do this work?

plz help me.

Hi @mell

Could you please clarify what you mean by "export PWM"? Also, if you could tell us a little more about your application, that would help us to better understand.

I want to implement the action so that the cylinder moves by sending the pwm to the motor driver when the button is turned on by receiving CAN data of a specific button. I'm not sure how to receive can data with the S32k146 evb board and export the pwm waveform.

Hi @mell

For a good starting point to understand how to implement CAN communication and generate PWM signals, I recommend checking out the example codes included with the available software packages for S32K1 devices. These examples are a great way to get familiar with the basic setup and functionality.

Additionally, I am attaching links to some documents and examples that will be helpful references.

AN12174: Using FlexIO to emulate communications and timing peripherals.
AN5303: Features and Operation Modes of FlexTimer Module on S32K.
AN5413: S32K1xx Series Cookbook.

Thank you for reply @VaneB

I'm trying to apply CAN and PWM example posted another blog and example. But it's doesn't work on my board.
I implemented it to always receive PWM and turn on green LED when I pressed the switch to see if I wrote the PWM receive code incorrectly, but the green LED is always on even if I don't press the switch. However, PWM doesn't output. I can't figure out which is wrong with pin settings or code implementation....

Hi @mell

Could you please point me to the example code you are using?

Additionally, it would be helpful if you could share any modifications you have made to the example code, the software version you are working with, and the IDE version you are using.
