Initializing PWM with specific duty cycle

[Shaked]

Hi,

I am using PWM to control LED power.

The code i use for initializing the PWM is-

app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_2CH(1000L, PIN1, PIN2);
err_code = app_pwm_init(&PWM1,&pwm1_cfg,vHAL_pwm_ready_callback);
APP_ERROR_CHECK(err_code);
app_pwm_enable(&PWM1);
while (app_pwm_channel_duty_set(&PWM1, 0, 0) == NRF_ERROR_BUSY);
while (app_pwm_channel_duty_set(&PWM1, 1, 0) == NRF_ERROR_BUSY);

The issue i have is that the PWM starts with 100% duty cycle which cause the LED to be on for a brief moment.

Is there is a way to initialize it with 0% duty cycle?

Thanks,

Shaked.

Hi,

I am still waiting for a replay. 

@Awneil-thank you, but this isn't what i need.

I would love some assistant.

Thanks,

Maybe, try changing the default pin polarity.

pwm1_cfg.pin_polarity[0] = APP_PWM_POLARITY_ACTIVE_LOW;

or 

pwm1_cfg.pin_polarity[0] = APP_PWM_POLARITY_ACTIVE_HIGH;

Did you try Ashish's suggestion? What was the outcome?
