I have been experimenting with using an Arduino to convert Resolver to Quadrature. I have it working for three simultaneous channels (you might squeeze more out of a Mega, but the Duemillenove only has 6 A/D channels) http://wiki.linuxcnc.org/cgi-bin/emc...atureConverter Using one channel of that converter and a PWM to gate trapezoidal commutation patterns on Arduino DIO pins to drive that 6-wire International Rectifier IRAMS10UP60A single-chip power driver I have semi-successfully driven a 500W brushless AC resolver servo at 300VDC.
