how to make PWM pulse in both channels

[karan]

Hi

i wrote the program which is making pulse one time on channel 0 and then followed by channel 1 and then again channel 0 and then 1 going on , my aim is to create pulses on both channel at the same time i tested by conencting buzzer on pin 6 and pin 7 so can anyone help me how to create that any help will be appreicated

Thank you

The pulses will not be totally synchronous if you use the driver. The driver can only set one channel at the time. You could use app_pwm_disable, but also here the output is set sequentially, so you will have an interval in time where one pin is high and the other is low. bottom line: You cannot do this with the pwm driver.

i am using this example from the SDK but this making pulses synchroncially in both pins for infinite time by adding this line

pwm1_cfg.pin_polarity[0] = APP_PWM_POLARITY_ACTIVE_HIGH;

then can you tell me how this working ?and also can you tell me how can i make condition for just five pulses (example just five times on and off uniformally) what condition do i have to set
