// This program tries to measure the width of the signal pulses in
8
8
// microseconds.  It takes several measurements and prints it the average over

// NOTES: Due to the way our receiver works (by varying the position of the
 
12
// rising edge of the pulse and keeping the falling edge fixed), it is
 
13
// sufficient for us to measure the pule width to determine the channel value
 
14
// (e.g., throttle position).  But it should be noted that this relies on a
 
15
// quirk of our receiver/transmitter and it is not truly measuring PPM.  Our
 
16
// next experiment is measuring PPM (../ppm-read).
