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