Setting 100% PWM duty cycle.

I'm was not able to reproduce this.

Could you provide a simple sample that reproduces this?

Again low level at the oscilloscope....

How about this then ?

pwm_set_dt(get_pwmmotor_device(), 0u, 0u);

Hi!

It does not work - produces low level at the PWM output.

// PWM output
static struct pwm_dt_spec pwmmotor = PWM_DT_SPEC_GET(DT_ALIAS(pwmmotor0));

const struct pwm_dt_spec* get_pwmmotor_device(void)
{
    return &pwmmotor;
}

void ol_set_output(void)
{
    pwm_set_dt(get_pwmmotor_device(), 100u, 100u);
}

I do not know if following in the device can produce this problem

compatible = "pwm-leds";

However I cannot figure what "pwm-leds" could be changed with...

Hi!

Does this work for you?

pwm_set_dt(&pwm_motor_0, 100, 100);
