NRFX_PWM and Zephyr PWM both used in one project

[Sebastor]

Hi

I am using several pwm outputs in my project. One of the outputs is used to generate a sound signal and the most convenient way is to use the nrfx_pwm_complex_playback function from the nrfx library. The other outputs are for LEDs control so I can just use the pwm Zephyr driver.
I am getting a conflict (run time error) during nrfx driver initialization, when both CONFIG_PWM and CONFIG_NRFX_PWM0 are enabled.
There is no problem when only one of them are enabled(I connected IRQ to nrfx irq handler)

Can I use both drivers at the same time in a project?
Are there any plans to implement nrfx_pwm_complex_playback equivalent in PWM Zephyr driver?

Hi,

What is the specific error you are getting? I suspect that you are getting an error because you are trying to initialize a peripheral which has already been initialized by Zephyr. If that is the case, you can disable the peripheral in the devicetree, and that should solve the issue. The devicetree is not used by the nrfx driver.

Hi,

I am curious to hear if you got this working correctly? I've been struggling a bit trying to play samples on the Thingy53 - and my issue sounds very similar. Maybe you have a snippet somewhere?
