that I can't claim for my own, a buddy asked me about it, I guess I'm a little slicker with the phone than he is... Here's what he wants to do, I think it's possible to get the hook-up, but translating the data I think would be the hardest part, if not impossible, for an Android app to do. But read on, let me know if you think this is possible.
He wants his phone (Moto Droid 1, pretty sure he's not rooted, so it'd be the latest OTA that was pushed) to connect to his truck's on-board computer. He's already built a box and is using SpeedView on my recommendation, because it's about as close to what he wants, as of right now.
He wants the app to read the data from the truck computer, and display it. Everything about his truck. Engine temp, oil temp, rpm's, pretty much everything that could be read off of the computer be read by the phone, and displayed to him.
I'm sure there could be a cord that you'd have to buy, to go from the computer (not sure what kind of cord that is), and connect to mini USB (phone). But for me, I don't think an Android OS would be able to convert the raw data from the truck. It's a fairly newer GMC/Chevy (I forget), and it has the V8, which drops to 4 or 6 on the highway, so I know the on board comp is pretty advanced.
What do you guys think of this? Is it possible? Would anyone be willing to dig around in the code to see if it is possible? I want to get in to app building/theming, but this is not a good first step to take.
