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').
