General Description: |
|
|
16 |
This module implements a function for debug logs on the serial line of the |
|
|
17 |
AVR microcontroller. Debugging can be configured with the define |
|
|
18 |
'DEBUG_LEVEL'. If this macro is not defined or defined to 0, all debugging |
|
|
19 |
calls are no-ops. If it is 1, DBG1 logs will appear, but not DBG2. If it is |
|
|
20 |
2, DBG1 and DBG2 logs will be printed. |
|
|
21 |
|
|
|
22 |
A debug log consists of a label ('prefix') to indicate which debug log created |
|
|
23 |
the output and a memory block to dump in hex ('data' and 'len'). |
