* Logging is a helper class to output informations over
|
|
* RS232. If you know log4j or log4net, this logging class
|
|
* is more or less similar ;-) <br>
|
|
* 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).<br>
|
|
* To reduce output and program size, reduce loglevel.
|
|
* <br>
|
|
* Output format string can contain below wildcards. Every wildcard
|
|
* must be start with percent sign (\%)
|
|
*
|
|
* <b>Depending on loglevel, source code is excluded from compile !</b><br>
|
|
* <br>
|
|
* <b>Wildcards</b><br>
|
|
* <ul>
|
|
* <li><b>\%s</b> replace with an string (char*)</li>
|
|
* <li><b>\%c</b> replace with an character</li>
|
|
* <li><b>\%d</b> replace with an integer value</li>
|
|
* <li><b>\%l</b> replace with an long value</li>
|
|
* <li><b>\%x</b> replace and convert integer value into hex</li>
|
|
* <li><b>\%X</b> like %x but combine with <b>0x</b>123AB</li>
|
|
* <li><b>\%b</b> replace and convert integer value into binary</li>
|
|
* <li><b>\%B</b> like %x but combine with <b>0b</b>10100011</li>
|
|
* <li><b>\%t</b> replace and convert boolean value into <b>"t"</b> or <b>"f"</b></li>
|
|
* <li><b>\%T</b> like %t but convert into <b>"true"</b> or <b>"false"</b></li>
