CAMAC Progress Report

                     Week Ending: October 26, 2001
                               Week: 39


Tom Folkers:
     1. Preparing for next weeks trip to Mt. Graham.

Tom Sargent:
     1. Finished detailed planning of the new encoder raw data 
        recording scheme. Started coding it. This will record sine, 
        cosine and reference pulse instead of just 2 of the 3 signals.
     2. Added the "load" command to servo so it can load command 
        scripts from a disk file. This was implemented so that it can 
        save certain configuration parameters on disk and then restore 
        them the next time the program is started.  The logic that 
        does this for the encoder signal to A/D channel assignment is 
        done and debugged. 
     3. Looked at the existing VAX/CAMAC servo software supplied to me 
        by Bill. My new algorithm is similar, though simpler.
     4. Fixed the "zero velocity" bug. The servo program previously 
        expected the telescope to stop when the velocity signal was 
        set to 0. In fact it has a very small drift. The program now 
        commands a "stop" whenever it also commands 0 velocity.
     5. Wrote some software to use the pointing model for the SMT.  
        Aldo supplied a program to read and parse the existing 
        pointing model file. I made a new version of ptmodel() which 
        should be able to use the constants supplied by Aldo's code.
