CAMAC Progress Report

                       Week Ending: May 18, 2001
                               Week: 16


Tom Folkers:
     1. Spent most of week hammering out the details of programming 
        the AM9513 System Timer Controller. Happy to announce that all 
        timing, blanking and sig/ref signal are now working. I now 
        have to begin porting the user level code into the Digital 
        Continuum Backend. (smtdbe)
     2. Designed a small interface board for signal conditioning into 
        and out of the smtdbe.
     3. I will be spending most of next week getting ready for the SMT 
        council meeting.

Tom Sargent:
     1. Spent some time studying Johann Schraml's code. I am using the 
        same program structure that he worked out. I also picked up 
        some good ideas from his code.  There are still some points I 
        don't understand. I will study it a bit more and then email 
        Johann about it if I still have questions. 
     2. I got the Host Linux machine and the DSP processor 
        communicating in a different, more efficient mode. Previously 
        they were using standard I/O (printf, scanf, etc.).  I have 
        now switched to using the Traquair Application Interface 
        directly to pass binary information back and forth. This is 
        the method that will be used for all communication in the 
        final control system.
     3. I began writing the realtime DSP code. I've defined a command 
        protocol for both directions and am writing the data 
        collection, correction, communication, and status reporting 
        code that executes on the DSP card. 
     4. I will be able to fairly easily make the system synthesize 
        encoder data by using data generation software I already have 
        running.  It will inject it into the DSP through the interrupt 
        routines just as if it was real encoder data.  (The interrupts 
        will come from the timers instead of the encoders).  The 
        software that calculates the corrections is already tested and 
        just needs to be grafted into the program.  This will allow me 
        to test out most of the logic without having the computer 
        connected to an encoder. This should be running in a week or 
        two??

Pete Hubbard:
     1. Prepare rear panel for A/D converter chassis. Start mounting 
        power supply and both A/D boards.
     2. Mounting fans and BNC connectors on rear panel of A/D 
        converter chassis.
     3. Vacation May 17,18 and 21.

Dave Ashby:
     1. No Report.
