libvas.a: MiniVas Programming Library
Introduction
The MiniVas library is a set of subroutines based on the vastools software
provided by Lyon-Lamb. This library is not included.
Procedure
Using the MiniVas software consists of three basic steps:
-
Call initmvas(portname) to initialize the serial communications with the MiniVas. portname is the character string of the seri
connected to, (/dev/ttyd1 at ER&E).
-
Call progmvas(start,framesper) to set the starting frame for recording, and
the number of video frames to record per each subsequent call to record(&cframe).
Both arguments to progmvas are integers (in C, not pointers to integers). The
argument cframe to record is a pointer to an integer.
-
For each rendered scene in the animation, call record(&cframe) to record
that
scene as a video frame. Depending on the framesper variable used in the
call to progmvas, the number of video frames recorded will vary. The
argument &cframe is set to the current video frame upon completion of the
record routine.
At the end of the recording, you may call close_port() to close down
serial communications. The same effect will happen simply by ending the
execution of your program, so this is optional.
