Sorry Bernd....... Pulse width modulation is an analog process. Not digital.
Hanging digital controls on another analog process does not make it a
digital process.

Good luck with your design. For your information, it is impossible to
measure voltage, resistance and current with a computer. You need precision
resistors, constant current sources, op amps, and analog to digital
conversion (A/D). You will need a shit load of A/D and D/A converters to
make this work. When it is done, you will still have a computer interfaced
to a whole lot of analog circuitry. If you can design this without a single
op amp or a single A/D converter, I will be the first to say I was wrong.
