BTM201.rss Programming Notes
When programming the BTM with the BTM201.rss code there are
several things to note:
1. You must in the N7 data table define words 16 thru 18. These
tell the program what the starting data table the BTMs use, the
slot location of the first BTM, and how many BTMs are in the
system. This information is move into the data table by the
initialization code in file 3.
Figure 9.1
2. The data tables that are used to hold the M1, M0, input image,
output image, and rotator information must be consecutive for
the ladder code to work.
3. The BTMs must be in consecutive slots for the ladder code to
work.
4. In program file two you will have to add copies for the input
and output images.
5. The example code has five BTMs in it. The BTMs are in slots 2
thru 6. The starting data table file that is used is N10. So the
information that needs to be code into N7:16 = 10, N7:17 = 2,
and N7:18 = 5
