/*
*  ======== ledprd.c ========
*
*  This example blinks LED #0 at a rate of about 2.5 times per second using
*  the LED module of the the DSK6455A Board Support Library.  The example
*  also reads the state of DIP switch #3 and lights LED #3 if the switch
*  is depressed or turns it off if the switch is not depressed.
*
*  When the program is run, DSP/BIOS initializes itself and calls the main( )
*  function.  Main( ) initializes the BSL then exits and returns control back
*  to DSP/BIOS.  The real work is done inside blinkLED0( ) which is a DSP/BIOS
*  periodic thread that is run every 200ms.
*
*  A second thread named blinkLED1( ) is also included that blinks LED #1
*  asynchronously with blinkLED0( ) to demonstrate DSP/BIOS multitasking.
*  It is not enabled by default but can be added by creating a new periodic
*  thread entry for it in the DSP/BIOS scheduler.
*
*  Please see the DSK6455 help file in the docs\hlp directory for more detailed
*  information.

/*
*  DSP/BIOS is configured using the DSP/BIOS configuration tool.  Settings
*  for this example are stored in a configuration file called ledprd.cdb.  At
*  compile time, Code Composer will auto-generate DSP/BIOS related files
*  based on these settings.  A header file called ledprdcfg.h contains the
*  results of the autogeneration and must be included for proper operation.
*  The name of the file is taken from ledprd.cdb and adding cfg.h.
