v) Monitor Channel: This command is used to select a channel that
is used to build up a serial string byte-by-byte from the animation
data, and then send it out at the appropriate time. It can be used
to send any ‘special’ commands you might need to send to the
equipment being controlled by the BR-SmartMedia. Any string of
any length up to 256 bytes can be built up and sent using this
feature. It is typically used to send commands to the serially con-
trolled equipment that doesn’t need to be sent regularly. Typical
of these commands are initialization and de-initialization strings.
This command asks for the address of an eight bit value in the
animation data. If you enter an address of 255/0FFh, this feature
will be disabled. Once set (and configuration mode exited), the
BR-SmartMedia will begin monitoring this location for any non-zero
values. Once it finds one non-zero value, it starts buffering what-
ever values it finds in this location in each subsequent frame of
animation data into a buffer. If it then finds two consecutive
frames of animation data with a zero value in them, it will then im-
mediately send out the entire string that has been built up.
The advantage of using this mode of sending strings is that
any string can be built up and sent from the animation data. The
disadvantage of this feature is that it takes as one frame of time
for each entry ion the string to be buffered in before it can be
sent. A 200 character long string will take 202 frames of data to
build up and send out. This translates to almost seven seconds at
30 FPS.
Data for these strings is typically hand entered using
PC•MACs’ OffLine editing tools. The target channel may be de-
fined as either a single eight bit analog or as eight separate digital
functions within the same byte. If it is defined as an analog, you
can use the ‘Set to a Value...’ commands to enter each frame of
the string (be sure to turn off the ‘Cut/Paste’ options under the
‘Preferences’ pulldown). If it is defined as eight digital channels,
you can just draw in the binary data as needed.
j) MIDI Keyboard Channels: This is a MIDI Mode specific command.
MIDI was designed for sending data from electronic keyboards
and instruments to one another. This feature allows you to define
sixteen consecutive bytes of animation data (128 digital bits) to
emulate a MIDI keyboard. This command sets the address of the
first byte used in this way. The other fifteen bytes follow immedi-
ately. If you set this value to 255/0FFh, this feature is disabled.
Once the address is set using this command and the configu-
