Warning lights ( eg. Low fuel)

[chiobups]

is there any program that is able to extract low fuel, low batt and etc data from flight simulator 2004 so that i can create a warning light module for my cockpit?

It must be possible via FSUIPC and a USB LED output board. I use the Flight Illusion I/O card in my Cessna C172 pit for the annunciators.

Hmm. Thanks for the information. However, I can't find the functions in the list of offsets.

I don't know about the battery but I suppose you need to calculate the available fuel and define a low fuel status and then light up an led.

This is my (not yet tested, sorry for that) version for the B727 fuel calculation in SIOC (mainly "borrowed" from Nico Kaan (who else :-)). Once you have your total fuel you can set "if total fuel < x pounds" then led y = 1. I plan to light up lamps for low total fuel and uneven fuel distribution between the individual tanks to manage cross feed as my fuel indicators don't work yet.

Are these of any use to you? Look also in the FS2Phidgets manual where there is an example of doing what you wish usinng an Phidgets LED64 card.
