Detailed Description

Mechanism to fire scheduled signals.

Entries for the sequencer are represented by pulse records which have these four attributes:

time – The time at which to fire the signal.
interval – Interval in which to repeat the signal.
count – Number of times to repeatedly fire the signal. Setting this to zero will repeat an unlimited number of times. A non-zero count is decremented every time the signal is fired, and when decremented form 1 to 0 the signal is removed from the sequencer. A negative count will halt repeating without removing the signal, which is a way to pause repeating.
periodic – The mode to repeat signals.
- 0 – the repeat signal is set to the sequencer handle time plus the interval. This means that the true interval between firings in likely longer than the interval setting, but such signals will never 'fall behind'.
- 1 – The time for a repeat signal is set to the previous time plus the interval. Note that this could lead to the system getting swamped by periodic signals. However, if the computation load varies a lot, this setting could allow repeats to 'catch up'.
- 2 – The time for a repeat signal is set to the previous time plus the interval unless such time has already passed in which case the time is set to the sequencer handle time. This is like setting 1 that will not fall behind.
- 3 – the repeat signal is set to the current time (after the immediate handling of the signal is processed) plus the interval. This is a sort of 'forced yield for a time' mode.
