   Microstep C program for National Semi LMD18245/PIC microstepping driver board.

   Changlog

   April 7, 2005 Added current reduction code, driver output current reduced 
   		 after 3 minutes. 
   		 
   		 Changed microstep10 pulse routine for faster step rate.

                 Added two new sine wave lookup tables, microstep8new and 
                 microstep10new. The lookup table is offset by a few degrees. 
                 These need to be tested to see if they work better.


   mstep.c		C source code for stepper board, compiled with PCW CCS 
   fullstep_627.hex	Hex flash program files for the various motor driver modes. 
   halfstep_627.hex 
   microstep4_627.hex 
   microstep8_627.hex 
   microstep10_627.hex 
  

   Hex files are compiled for a Microchip PIC16F627 mcu.
