Description
The PIT class controls the PC's Programmable Interval Timer (PIT).
Public methods
PIT (int us)- The timer is initialised in the constructor in such a way that it regularly triggers interrupts
at intervals of approx. us microseconds. Since the resolution of the timer component
is a maximum of 838 nanoseconds, it is not possible to make a completely exact setting in the
microsecond range.
int interval ()- Indicates which interrupt interval was set.
void interval (int us)- Sets a new interrupt interval.
