XTimer is a useful tool for measuring time durations - for example, if you want to measure how long it takes for a program to run.
XTimer offers these features:
* Countdown Timer - counts down (like a microwave oven timer) from some HH:MM:SS value to zero. * Stopwatch - continuously counts up until stopped. * Play a wav file - when the countdown timer expires, XTimer will optionally play a wav file. * Compact size - takes very little space on the desktop. * Play once/Play until stopped - play the sound only once, or play it continuously (every 30 seconds) until the Stop button is clicked.
