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.
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').
