Hi,

The counter API provides exactly that: https://docs.zephyrproject.org/latest/reference/peripherals/counter.html

Hello. I use stm32f429 and Zephyr Os 2.7.0

Is there any API for timers with fixed interrupt period?
I need to change PWM duty cycle exactly every 1000 us. In bare-metal I would have used general purpose timer with fixed interrupt period, and changed duty cycle in interrupt handler
But how should I manage with such task under Zephyr Os?

Thank you
