// AUTHOR: Rob Tillaart
|
|
// VERSION: 0.1.03
|
|
// PURPOSE: Simple StopWatch library for Arduino
|
|
//
|
|
// The library is based upon millis() and therefore
|
|
// has the same restrictions as millis() has wrt overflow.
|
|
//
|
|
// HISTORY:
|
|
// 0.1.00 - 2011-01-04 initial version
|
|
// 0.1.01 - 2011-01-04 Added better state
|
|
// 0.1.02 - 2011-06-15 Added state() + #defines + lib version
|
|
// 0.1.03 - 2012-01-22 Added several improvements
|
|
// By mromani & Rob Tillaart
|
|
//
|
|
// Released to the public domain
