Description

Methods

Public function GetTickCount: TMicroseconds; virtual; abstract;

Returns the current value of system timer, in microseconds.

Public function TicksInBetween(const InitTicks, EndTicks: TMicroseconds): TMicroseconds;

Calculates the difference between two system timer values with proper handling of overflows.

Public procedure BusyWait(const Microseconds: TMicroseconds);

Waits the specified amount of microseconds accurately by continuously polling the timer. This is useful for accurate timing but may result in high CPU usage.

Public procedure Delay(const Milliseconds: TMilliseconds); virtual;

Delays the execution for the specified amount of milliseconds. CPU is put to sleep when milliseconds > 10

Public procedure MicroDelay(const Microseconds: TMicroseconds); virtual;

Delays the execution for the specified amount of microseconds.
