TNG Tip-Tilt System 
Supervisor Library Reference Manual

Abstract

The following manual describes a library of C subprograms which may be used as building blocks for the development of the TNG Tip-Tilt system software on the Supervisor.

The Supervisor is a 68040 based board which communicates through the VME bus with a DSP 56001 based board (Loughborough DBV56H) where the Tip-Tilt loop is implemented. The purpose of the library is to make the development of the tip-tilt loop control software easier both for the implementation in the laboratory and for the final version at the telescope.

This software has been implemented by Luca Fini and Piero Ranfagni at the Osservatorio Astrofisico di Arcetri as part of the development of the Tip-Tilt correction system for the Galileo Italian Telescope (TNG).
