      Hi gents,
      I want to use a hall-based current sensor on a DC-motor and control torque by PWM'ing a heater output. The feedback loop is the aforementioned linear sensor on a thermistor header.

      Different to a usual heater-cartridge I want to be able to set a minimum PWM-duty to keep an external motor driver initialized.
      How can I achieve this?
      I also want to use a high PWM frequency and a slow feedback loop, but I'm not sure what the default ratio is?
      (thermistor read once per main-loop and heater PWM frequency is xxx-times faster?)
