Hi Simon,

Thank you. I will try to study "pwm_driver" sample code and merge it to my environment, then test it's behavior

Best Regards,

Due to the Easter holiday you will have to expect a delay in replies, sorry for the inconvenience!

I think you should take a look at the pwm_driver example in our SDK, as it describes how it is working with the PWM_driver in detail, and in multiple scenarios. It will probably help you get some insight in how the peripheral works.

Also you could have a look at this case, where an example using ble_app_uart and the PWM_driver together for easy modification of the PWM duty cycle. They also have a good discussion on how to implement PWM.

As for StepCntInitial I am not quite sure what you mean. What parameter do you want to set it as,. How do you want it to work?

Best regards and happy Easter,

Simon

Hi Simon,

Yes, the output wave-form some times is correct, some times is wrong, but I don't know its rule.

By the way, how can I set StepCntInitial parameter?

Can you clarify one thing for me. Are you getting the correct amount of steps sometimes, and sometimes not. Or are you always getting the wrong output?

Also, have you tride setting your StepCntInitial to for example 1, to see how many steps 1 of these step counts provide?

Best regards,

Simon
