New DAQ scheme

• Addresses several issues:1. Rob’s DAQ modified to cope with two bunch

mode known not to correctly perform interleaving of feedback, latency scans

2. Necessary to maintain a separate instance of code for each board – to add new features, each must be modified

3. Code distributed and difficult to manage

Improved VIs

• FONT5_board.vi– General improvement to legibility– Live monitoring of DACs– Direct referencing of control registers

• Mover_control.vi– Parallel execution enabled

• Scope_daq.vi– Single sample mode added

D. R. Bett FONT Meeting 5th May 2012 6

Brand New VIs

• Main.vi– Monitor board data– Synchronize data logging, interleaving

• Scan.vi– Automated variation of parameters

• EPICS.vi– effectively “spun out” from FONT5_board.vi

• Hardware_assignment.vi

Summary

• No functionality lost

• FONT5 board VI– more generic– less monolithic

• All hardware code collected together

• Facility for automatic parameter scans

• Some bugs to iron out
