Detailed Description

The timer.

This class provides a timer which can be used in the working loop of the control programs. The working loop must run continously, this way sleep can not be used, because sleep suspends the working loop, and input changes can be missed. This is why a timer is needed, which can be started, stopped, and restarted automatically, or triggered way, and it timeouts based on delta time.
