We intend to eventually phase out the old fast feedback software. It is essentially complete. To make this article a useful reference document, it and the touch-panel help describe version 2.0. Parts which are not done yet are so noted in parentheses. This document only gives a brief introduction to fast feedback and explains some operating procedures.
Extensive documentation is available elsewhere.
Every button on all 9 fast feedback touch panels has online help. The main help for some of the touch panels include descriptions of methods used and definitions of some terms. The System Requirements for Fast Feedback document tells what feedback is intended to do. The Fast Feedback System Design document gives a top level view of how fast feedback works. Many more documents giving the detailed design have been written.
