Thanks to Philipp posting these dataref's, I built my first test panel box. Here's a quick rundown. I purchased a GP-Eiz40 MAX Usb Controller, a project box and a bunch of single-pole double throw switches, LED's and pushbutton's with LED's in them. The goal was to try and build a few of the most common overhead panel buttons such as the APU buttons, 10th stage APU/LCV, ISOL and so on. Having a little background in electronics (it's been years), I was able to simulate most of what I wanted. Although my project box wasn't big enough to hold everything I wanted, such as the Packs, I was able to get most of the big ticket items. The hardest part was trying to figure out what xjoymap and button2dataref was and the relationship between them. Being a former MSFS fanatic, X-Plane is fairly new to me. I did have a few issues with the Hydraulic buttons. Switch 1, 3B and 2 where initially backwards. For example, when throwing the switch to the ON position ( 1 ), those three switches would not throw correctly. I finally figured it out and that's for another post. If anyone is interested, I can post what my button2dataref config looks like. The other issue I had is the landing lights. For the life of me I can't find any reference to the three landing lights (Left, Center and Right). It's an all or nothing which forced me to abandon that idea and reprogram my landing lights switches to Nav, Beacon and Strobe. I also couldn't find a dataref for Logo lights either. If anyone is interested in what parts I used, feel free to reply. It was a fun project and I plan on expanding this idea. Here's a quick 30 second video of it:
and I'm also attaching a few pictures.
