Description: This module is responsible for providing a
|
|
|
32 |
debug interface to the system. Currently, the only
|
|
|
33 |
debugging that is available is through the on-board
|
|
|
34 |
UART (which is used by the main application as well) in
|
|
|
35 |
addition to the LED hooked up at PORTD bit 6.

Function Name: DebugInt_init
|
|
|
59 |
Function Description: This function is responsible for
|
|
|
60 |
initializing the debug module. It sets up the debug LED
|
|
|
61 |
as well as any other debugging that will be done. The
|
|
|
62 |
LED blinks four times, which indicates to the user
|
|
|
63 |
that the system is available for re-programming if
|
|
|
64 |
necessary. This works because the data lines on the
|
|
|
65 |
OV6620 are still tri-stated at this point, but won't
|
|
|
66 |
be for long after this function returns.
