Setting PWM signal level

I am using imxrt1064 and the pwm example as a starting point. I can setup the PWM duty cycle and frequency. The PWM signal is always 3V/0V. Is there a ways to setup the PWM signal level to e.g. 0.4V?

Hello Gamka,

The PWM module has several features that are describes in the Reference Manual, but it has a fixed voltage level to the same level as the GPIO signals.

My apologies for the inconvenience.

Regards,
Gustavo

Could the PWM signal be somehow routed to some DAC and then set the DAC value? I just realized, that apparently there is no DAC in imxrt1064... So I guess no.
