5th_spwm_attempt.ino

Code intended to allow an Arduino motor-shield to do a half decent job of creating an AC waveform.

Tried to use port registers to do the bulk of the work, in order to allow higher frequencies to be used. Have only succeeded partially in this endeavour, the inverting part uses port registers but the duty-cycle manipulation is performed by Arduino functions.
