Whats the maximum interrupt frequency handled by TVicHW32?
TVicHW32 runs perfectly up to 10 KHz on a 450 MHz Pentium II. For very stable results we recommend TVicHW32 be used with interrupt periods less than 10 milliseconds. TVicHW32 handles all interrupts at higher frequencies, but it starts to influence the delays that occur when interrupts are delivered to the application level. This is possible only when Windows makes TVicHW32’s thread active. For TVicHW32 to have this indirect delay effect its priority class must be REALTIME_PRIORITY_CLASS and its thread priority set at THREAD_PRIORITY_TIME_CRITICAL. In this extreme case we start to have problems with the keyboard and mouse which can even be blocked.
