Pete,
I think I read that somewhere.... :) I too was on this (PM SYSTEMS FOR DUMMIES) Quest.
I had a conversation with Thomas Richer (PMSYSTEMS KING) and was trying to probe him for a what do I do first. I personally have spent hours just trying to edit an existing 737 or airbus overhead. By just trying to move a few switches from one position to another, completely without success.
I can't even seem to change the look of the bitmap. LOL. Anyway Thomas basically just said keep plugging away on it and it will eventually start to work. I asked him how many hours would it take him to build an overhead?
His response was unclear as he stated it starts off with needing to draw out a function map, like a flow chart to see how it all fits, then begin programming. I even told him I didn't want fancy graphics, Just all my switches lined up waiting to be commanded from hardware.
I got no bites :). As more people in the community plug away with PM systems, we will get our How too booklet, I for one am hoping someone learns it so well, For a couple hundred bucks they will build my overhead for me........ But I think I am dreaming :)
Best regards
Trev
