This class provides functionality useful for debugging sketches via printf-style statements.

ArduinoDebugUtils has 6 different debug levels (described descending from highest to lowest priority):

• DEBUG_LVL_NONE - no debug output is shown
• DEBUG_LVL_ERROR - critical errors
• DEBUG_LVL_WARNING - non-critical errors
• DEBUG_LVL_INFO - information
• DEBUG_LVL_DEBUG - more information
• DEBUG_LVL_VERBOSE - most information

The desired debug level can be set via setDebugLevel(DebugLevel::Warning).

Debug messages are written via debugPrint which supports printf-style formatted output.

Example:

int i = 1;
float pi = 3.1459;
ArduinoDebugUtils.debugPrint(DEBUG_LVL_VERBOSE, "i = %d, pi = %f, i, pi);

If desired timestamps can be prefixed to the debug message. Timestamp output can be enabled and disabled via timestampOn and timestampOff.

Normally all debug output is redirected to the primary serial output of each board (Serial). In case you want to redirect the output to another output stream you can make use of setDebugOutputStream(&Serial2).
