 2  	Example: hsc_counting_mode
 3  
 4  	This example shows how to configure an HSC channel with different counting modes.
 5  
 6      This example works with the P1-02HSC
 7  
 8  	This example will configure channel 1 as a Quadrature 1X counter and channel 2 as
 9      a Quadrature 4X counter. The default mode before configuring is Step Direction.
10      It will then print the position of each channel every second.
