Module Name: DebugInterface.c |
Module Date: 04/15/2004 |
Module Auth: John Orlando |
|
Description: This module is responsible for providing a |
debug interface to the system. Currently, the only |
debugging that is available is through the on-board |
UART (which is used by the main application as well) in |
addition to the LED hooked up at PORTD bit 6. |

Function Name: DebugInt_init |
Function Description: This function is responsible for |
initializing the debug module. It sets up the debug LED |
as well as any other debugging that will be done. The |
LED blinks four times, which indicates to the user |
that the system is available for re-programming if |
necessary. This works because the data lines on the |
OV6620 are still tri-stated at this point, but won't |
be for long after this function returns. |
Inputs: none |
Outputs: none |
