Jon, I thought something was amiss because I stuck a LED on the motor port and it lit up once and never went out.  The new code works as I expected it should. And thanks for the explanation.  I'll stare at the code a little and try to figure out how to integrate the footswitch (on my own <g>).

By running at 4MHz instead of 20, the ISR is still run 153000 times per second, but all the other timing is off, right?  The one second pauses are now 5 seconds (of course).  So did the pwm frequency go down to 100Hz then?  Doesn't really matter, I guess.  And I think I'm getting a scope on Monday (a real Tektronix (sp?), not a usb).  That'll help me make sense of it all.

Thanks again,

Larry
