- 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').
