added bitwizard hardware and shortened a few lines. 

I've simply added the config for the bitwizard hardware. 

Looking at the lines containing "0.001" intending to change them to a configurable parameter, 
I cleaned those up a bit: I suddenly saw that the "0.001" isn't the step size used for the pwm ramp, but a safety margin for setting the MIN PWM. Why it looked as if this was necessary yesterday I don't know. 

I'm not near the hardware right now. Can't test. It compiles though!
