dwell angle control

[Huw Scourfield]

Carsten, I used the complete module from a bosch reluctor system driven by a
logic signal( from a 16f877), the module worked no problem, didn't see any
reason to use anything different. If you use this you need to use the
correct coil since they are pretty much a matched set. (I believe)
