I have looked around, maybe I am missing it, and I can't seem to find what I can use to have an external display of Heading and Course etc. I would like to build a generic panel where i can control heading and course and AP functions. Now i have found interface boards with rotary encoder capabilities etc and building the panel won't be a hassle (much) BUT, how would I, for example, have the heading show on an external 3x7 segment display with heading rotary below i.e. 737 panel.
Thanks in advance.
