Hi Jacob, I've listed below various soft PWM implementations I've bumped into over time, I thought they might make a handy reference for you: ARM Mbed: https://github.com/ARMmbed/mbed-hal-nrf51822-mcu/blob/master /source/pwmout_api.c 3rd Party support for Arduino IDE: https://github.com/RedBearLab/nRF51822-Arduino/blob/S130/ard uino-1.6.x/hardware/RBL/RBL_nRF51822/cores/RBL_nRF51822/wiring_analog.cpp https://github.com/RFduino/RFduino/blob/master/cores/arduino/wiring_analog.c https://github.com/sandeepmistry/arduino-nRF5/blob/master/ cores/nRF5/wiring_analog_nRF51.c Nordic example: (although this probably is very much superseded by what Nordic includes in their SDK these days, as pointed out by Andrey) https://devzone.nordicsemi.com/question/798/is-there-an-exam ple-code-for-using-pwm-on-the-nrf51822-with-a-softdevice/ Hope it helps.

Re: Writing PWM api, and nrf51 implementation
Looks like lfclk is now used for low power mode you added, so maybe thats not a good solution either. I wonder how decent a soft pwm with just callouts could be.
