Exorcist User Manual

Protection against running multiple routines to the same output device.

This problem can be something of a nuisance, during the development of Exorcist; we

were met with the dilemma of permitting Exorcist to run multiple routines

simultaneously, yet sidestepping the problems that can arise, should VSA try to send

multiple commands to a serial port from different routines.

Without limiting Exorcists power and versatility it was finally decided the leave the

control in the hands of the user.

The important thing to remember is that neither VSA nor Exorcist has any way of

knowing which routines will be played simultaneously to the same port and which

won’t. You as the programmer need to make this assessment and add protection,

otherwise you will suffer crashes or ‘interesting’ and potentially prop damaging

results.

This first example will use the All routines off, this methodology only works if you

have a single set of props with multiple routines, and should not be used in a multi

‘room’ setup otherwise actions on one set will disable the others.
