Skippy, I have googled to see if there is a Mac plugin for the Saitek LCD Instrument Panels and as far as I can tell, there isn't one. Tom Sedge is the guy who wrote the plugins I'm using for my Saitek panels. I've PM'd him at the org to see if he would write a plugin for the LCD Instrument Panels and the new TPM Module. The TPM (throttle, prop, mixture) module gives you vernier controls and 9 programmable switches but there isn't a plugin for Mac to program the switches. The throttle, prop and mixture controls work great, but the switches will require someone writing a plugin. Tom's response about the Instrument Panels was that he didn't have the money to buy one to work on a plugin but when he had the chance he'd look at it. Here's what he had to say about the TPM module: "Hi Steve, I'm glad you are enjoying the plugin. Truth be told, I haven't had any time to work on it for a long time now (over a year) as I've become busy setting up my own business. So I don't have any time available at the moment to extend it to work with the TPM module, though I'd certainly like to at some point (I don't have it myself yet but if things go well, I'll get it). I also don't have time to help you with this in any detail. Yes, X-Plane only deals with buttons, not switches, so only one position will register. My plugin is written to handle each different type of input control on the panels, so it can detect switch positions and map them to whatever functions are needed in X-Plane. As you say, choosing what to map them to is a good question. For everything on the other panels it has always been possible so far to map to something appropriate, so I haven't needed to consider a choice. I suppose ideally there'd be something like the existing X-Plane configuration GUI, where you can toggle the switch and then choose what you want to it to toggle. Programming that would require GUI work on top of support in the panel coding, making it more complex. Though it could perhaps just be done in an XML configuration file. Have you done programming before? If not, you'd be starting with a challenge. If you have, then it isn't that hard. You'd first need to master the X-Plane SDK - see Sandy Barbour's materials and write yourself some plugins to make sure you get the hang of it. Then you'd need to master OS X USB work and learn more about how USB works. Apple provides a good toolkit and instruction manual on Leopard and Snow Leopard. I'd suggest you do the following: 1. Master writing X-Plane plugins on OS X (if you don't know how to already). 2. Master OS X USB work using the apple toolkit. 3. Write yourself a test program that allow you to talk to the TPM module - There a free HID example in the Apple toolkit that will tell you what the panel USB ids are for the various buttons. 4. When you can control and read everything on the module, write an X-Plane plugin to wire it up to the datarefs/commands of your choice. The resulting code won't be complex. I found the work was all in mastering the SDK, USB layer and figuring out how to read and control the panel. That's what takes the time. Tom"
