Re: [WheelWatcher] WW-01 Code

Curt,

I hooked a PIC 16F877 board (a Junun MarkIII board) back up, and tried 
my example program using Parallax servos.  It exhibited some behavior 
that sounds similar to what you see.  Other than small errors in zeroing 
the servos, they do spin when requested by the various tests.

This behavior is that a wheel spins when it is not supposed to.  This is 
because the servo is not properly adjusted, so the 1.5ms neutral pulse 
width causes it to spin slowly.  Since the Parallax servos do not have 
an adjustment potentiometer, my example program would need to change to 
allow you to set the neutral pulse width of each wheel separately.  It 
would also need to add a way for you to interactively find the correct 
neutral pulse width.

I may add these features to it.  Meanwhile, have you had any progress?
