https://devzone.nordicsemi.com/f/nordic-q-a/7225/nrf51822-pwm-library-on-mbedHello, I am trying to use the &#39;nrf51-pwm-library &#39; on mBed with a nrf51822 on RedBearLab Nano. I copied the nrf_pwm.h/c files and they compile, but I never get any sort of signal out of the PWM pin. (Pin 19 on the RBL Nano is an on board LED.)

I think it has to do with how mbed handles interrupts. It stops in the call to NVIC_SetPendingIRQ(PWM_IRQn).</p> <p>However, mbed has a PwmOut class that is easy to set up. You can read about it here: <a href="https://developer.mbed.org/handbook/PwmOut">developer.mbed.org/.../PwmOut</a>. The example code provided works out of the box with the nRF51-DK.</p><div style="clear:both;"></div>
