| 15 | 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').
