// TITLE:   Wheel Abrasion Detection Program for Using TMS320F2812.
//
// ASSUMPTIONS:
//
//          This program requires some relative header files.  
//          As supplied, this project is configured for "boot to ZONE2" operation.
//
//          Other then boot mode configuration, no other hardware configuration
//          is required.   
//
// DESCRIPTION:
//
//          This is an example for detecting abrasion of train. And it will be 
//          used in spot running. The main purpose is that the measurement data
//          are obtained by the program for reasearching the characteristic of
//          abrasion of wheel.
