Gilderfluke&Co Analog Output Smart Brick (ver 2.nn w/Eprom memory) - Manual (Page 13)

Animation Data Eproms:
The Eproms used for all all of the 'Brick' products manufactured by Gilderfluke & Company have tradi-
tionally each contained one channel (eight bits) worth of data. The Eproms used on the BS-ANA, EFB Smart
Brick and RTU/FSK Units for storing animation data each carry a number of channel's worth of data. The first
four bytes also contain the frame rate, number of channels and the length of the first show in the Eprom.
These are generated on a PC¥MACs system by:
1) Selecting the 'Save as Eprom...' command from the 'File' pulldown.
2) Check on the 'Multi Channel' checkbox
3) Set the 'start' and 'end' boxes to set the number channels you want to go into this multiple
Eprom file. A BS-ANA with all sixteen channels set to eight bit resolution, this will be sixteen
channels. A BS-ANA with all sixteen channels set to twelve bit resolution, this will be twenty-four
channels. If you are saving a twelve bit resolution Eprom, you must set the ÔstartÕ address (and
the BS-ANA address) to a multiple of three (or zero). Be sure to allow for enough extra channels
for any Z-Bricks that might be attached to the BS-ANA.
4) Use the ÔAddÕ button to select any additional show you would like to be saved into this Eprom
file set.
5) Use the ÔPromoteÕ and ÔDemoteÕ buttons to move selected show(s) into the order you would like
to save them in the Eprom.
6) Normally you will want to select the ÔCalculate Brick Start FramesÕ checkbox to allow PC¥MACs
to automatically calculate the offset into the Eproms needed for the shows you are saving. If
you would like to preserve the ÔStart frameÕ values in the show files, also check the ÔSave Brick
StartsÕ checkbox.
7) If you are not using the PC¥MACs calculated ÔBrick StartsÕ, you will have had to set these indi-
vidually for each show under its File/Show Information dialog. If they are set improperly,
PC¥MACs will tell you if any of the shows are overlapping during the build. When using ÔBrick
StartsÕ that you have entered, PC¥MACs can pad the space between the shows with the de-
fault values for the movements if you have checked the ÔPad With Default ValuesÕ checkbox.
8) Press the ÔBuildÕ button to begin the saving process. A standard file save dialog will open.
Name the file as desired. (it defaults to the name of the first show in the list). PC¥MACs will
warn you if a file already exists with this name. Hit OK to save the data to a file.
Once the shows have been saved to the multiple show file, you can burn them into an Eprom using
any Eprom programmer that supports 27C010 through 27C080 Eproms.
If you press the ÔReportÕ button, PC¥MACs will display the information about the Eprom set you just
saved. This information is also saved in a text file with the same name as the Eproms, but with the exten-
sion of Ô.setÕ. You can open this file with any text editor like Notepad or Wordpad. The numbers shown for
ÔBrick startÕ and ÔBrick endÕ are what you need to enter into the Smart Brick Brain to set the start and end of
each show. The ÔEprom startÕ and ÔEprom endÕ are the actual locations of the shows in the Eprom set. The
number shown for the ÔEprom EndÕ for the last show in this file set is the last byte which will be saved into
the Eprom. If your Eprom is smaller than this number, you will need to use more than a single Eprom and a
memory expansion board for the BS-ANA. The capacities of all of the large Eproms are as follows:
Eprom type Total number of bytes
27C010 131,072
27C020 262,144
27C040 524,288
27C080 1,048,576
If additional capacity is needed, then a memory expansion board can increase the capacity of the BS-
ANA to eight 27C080Õs (8,388,608 byte capacity).
Note that at least one show must be loaded starting at a 'Brick Start' of 0, even if it is only a frame or
two long. PC¥MACs will use this first show to set the frame rate and number of channels stored in the multi-
ple channel Eprom. The BS-ANAs need this information to index into the Eprom.
