Detailed Description

Logging is a helper class to output informations over RS232. If you know log4j or log4net, this logging class is more or less similar ;-)
Different loglevels can be used to extend or reduce output All methods are able to handle any number of output parameters. All methods print out a formated string (like printf).
To reduce output and program size, reduce loglevel.
Output format string can contain below wildcards. Every wildcard must be start with percent sign (%)

Depending on loglevel, source code is excluded from compile !

Wildcards

• %s replace with an string (char*)
• %c replace with an character
• %d replace with an integer value
• %l replace with an long value
• %x replace and convert integer value into hex
• %X like x but combine with 0x123AB
• %b replace and convert integer value into binary
• %B like x but combine with 0b10100011
• %t replace and convert boolean value into "t" or "f"
• %T like t but convert into "true" or "false"

Loglevels

0	LOG_LEVEL_NOOUTPUT	no output
1	LOG_LEVEL_ERRORS	only errors
2	LOG_LEVEL_INFOS	errors and info
3	LOG_LEVEL_DEBUG	errors, info and debug
4	LOG_LEVEL_VERBOSE	all

History

01 FEB 2012	initial release
06 MAR 2012	implement a preinstanciate object (like in Wire, ...)
	methode init get now loglevel and baud parameter
