Offset 282C issue

[cjellwood]

Hi Pete,

Recently I attempted to crate a gauge in my project for 'battery load' which is offset 282C. I have a strange problem with its output that is really baking my noodle as I have never come across this issue before having used over 50 offsets so far in my project. When I read 282C using the interogator it shows the corect values i.e value = 0 during normal flight or value = -12 when there is an electrical failure. That is great but when I use this offset in my software it does not give the value = 0 during normal flight? What I get is a fast flickering of values between -1 to -9 ?

My read code is very simple

Dim ElecBattM As New Offset(Of Double)(&H282C)

and there is no factoring applied.

The strangest thing is that during an electrical failure it does give the correct value i.e value = -12 as it should.

So why am I getting a good value from interogator but flickering wrong values in my code? It does not make sense! :roll:

Have you tried using the real time monitoring facility in FSUIPC -- Logging page, right-hand side. You can have it displayed on screen. You can also log the values you are actually reading.

Please use all of the tools available to you.

I cannot really check anything specific for you here as you fail to mention either the version of FS (FS98, FS2000, FS2002, FS2004, FSX, ESP?) or the version of FSUIPC. Please always do so when asking questions here. I just monitored it (to screen and log) in FSX and whilst the screen value (which is in notmal decimal notation) gives 0.0000000 al the time, the log shows the value as being very very small but varying all the time. e.g.

Maybe you are getting these values, which because of the exponent of -100 or more sre EXTREMELY small, almost zero, but you are converting them into print or display incorrectly?
