How do I write my own FSUIPC offset with an LVAR to work with mobiflight

[Myles_DJL]

Hi All

I have started the process of creating replica gauges for the P-51 and B-17, with the end goal of having them work with their counterpart A2A aircraft. 

Step one was to model the gauges and work out the mechanical side which I have done, I plan to use Mobiflight and Stepper motors for most gauges, the next step it to work out what LVARS are driving the gauges in the A2A aircraft, I am hoping to achieve this via LINDA. My question is, how would I go around writing the LVAR for say the Hydraulic gauge, to one of the spare FSUIPC offsets so that it can then talk to mobiflight ?

I am quite the novice when it comes to this, I know how to use existing FSUIPC offsets with Mobiflight, but when it comes to writing my own, I wouldn't know where to start.

Thanks in advance for your help

in FSUIPC6 and earlier, you need a simple lua script to write the lvar value to an offset when the lvar value changes, using the event.lvar function.  See the following post where i explained in more detail on how to do this: 

You can also enable writing to the offset to update the lvar if you like, by using the event.offset function. 

In FSUIPC7, a mechanism is provided to add lvars to offsets for both reading and writing by using the FSUIPC7.ini file. This is explained in the Advanced User guide.

Thanks John, I get how this would work for switches, but I’m not sure how I write the code for gauges and what values/variables to have, I’m probably overcomplicating it in my head, but I just can’t get head around how to write the code, maybe if I understood what the various elements of the code did it would make it easy to understand? Would you be able to walk me through it, I’m a complete novice when it comes to this.

thanks

No, sorry - I do not have any experience in gauge programming - that is a completely different ball game. I am only familiar with the SimConnect Sdk, not the gauges API.
