able to convert to revolutions per second, which will give me speed. How
accurate I need this is something I can't quite say at this point. The
pulses per shaft revolution are probably so high that at max loaded speed,
they will be "off the chart" for the OOPic, which means that I will have to
generate a curve of rps vs speed setting, and extrapolate the higher speeds.
If that is the case, then I barely need to even have an answer, since once I
know the curve, I won't actually need to record the pulses anymore. The
purpose for the 1Hz signal is simply that it is a nice regular interval to
do the math with.
I may not have the very latest V.6 compiler, either. I downloaded one that
was something like the second beta, and forgot to check to see if the final
was out. I assume it is, but I'll go have a look.
