The PWMOutput example sets PWM source to a fixed frequency and duty cycle. The PWM output can be observed on D2 (J9 pin 3).

/*Sets PWM source to fixed frequency and duty cycle. Observe output on oscilloscope.
                                                                  */
#include "mbed.h"
PwmOut pwm(PWM1);               //create a PWM output called pwm on pin PWM1

int main()
{
    pwm.period(0.010);                // set PWM period to 10 ms
    pwm=0.5;                         // set duty cycle to 50%
}
