Works with the power button,switches the screen off AND starts in exactly the right place when pressed again.Now all I need to do is to figure out how to synchronise this with my ignition on/off.

No problem ... just drawing on hours wasted fiddling with flirc, etc. I need to get a life!

Yup; here relating to communications over the bus and just the IBus. The reverse engineering of the command started simple back in the 1990's. That said someone did figure out a means to create a device on the car bus initially talking directly via a serial port; then a USB port. Note that while this information did spread much in the carpc community; it was shunned by the manufacturer as they prefer that this information stay in the "recesses" of the engineering group et al. I recently asked an old friend here whom mostly worked on the electronics and bus communications for GM cars about certain mechanisms of action relating to newer transport and the use of the OS in the HU. Old friend of many many years; wouldn't say or tell me.

Today the IBus has been replaced with some means of faster communications (well its still serial I think).

Fast forward to your endeavor and the product you are using; "JoyCon Exr". Someone out there in internetlandia has figured out the methodologies of communications (whatever standard they are) and wrote a piece of software that communicates with the device in question. Personally my software "sniffed" the IBus in vivo (I would push the steering wheel button) and map the command to some keystroke or whatever on the PC. It is a pain in the butt to sit in your vehicle with a computer sniffer and watch; its also very time consuming; but the benefits are great.

Here there is a time lag when devices shut down in the automobile; which can be good or bad. It was bad for me when my new car Blue Tooth communications kept that channel open even after bringing the phone into the home. Initially under warranty my car battery was changed some 3 times. The 4th time the company would not admit fault and basically told me it was my fault? That said I just purchased a new battery at my expense. Then later the company admitted to faults in the firmware of the computer piece of the blue tooth module that would leave it on when the car was off; which was a bad thing.

Ok thanks for that Pete.

There are lots of ways I can do this.The main problem is that all my remote controls for the Joggler are in the steering wheel and I have no spare wires as they're all used up getting power etc to my infra red transmitter.I've got a spare Flirc which I could plug into the Joggler,but I'd need to build and fit another teachable i/r transmitter plus some other bits to send the Q every time I switch the ignition on and again when I turn it off.(I think a simple 555 astable circuit would do this).
Or I could do it via USB with the CarPC JoyCon Exr without faffing about with all this needless i/r stuff,but again using the astable thing or what ever it is.Or would there be an ever easier way using just an Arduino that would store and transmit the same data as when I press the Q key on a full keyboard?

i/r transmitter plus
Understood.

Personally here never did automate at home with IR. It was never a "sure bet" of 100% functionality. Way back though in the old Tivo days I did hand write commands such that my IR blaster remoted the commands for the Tivo remote. I mean it worked but it wasn't optimal. I have one IR transmitter for the device video adjustments that tap into the HU video (well its RGB). It is though behind a panel with the rest of the stuff in a sort of modular rack. BMW does the same for my E83 and E46. It's a PITA to set the video adjustments and I never did install the IR blaster cuz its a one time thing. So here I open the "door" to the rack and point my remote to the device while looking at the display in the front.

Talking to the bus only requires one connection. Kind of like one network connection that talks to a bunch of devices.

Here for the addition power always on I went straight to the battery with a fused link. For the ignition side of it went to the fuse block with a fuse link.
Or I could do it via USB with the CarPC JoyCon Exr without faffing about with all this needless i/r stuff
Yes

I reckon this should suit my needs perfectly......

As long as I regulate it down to 5 Volts,it can be programmed to respond to the ignition on/off states without any further circuitry.

Very neato. I have never seen something like that and that small.

Maybe some of these would be of interest as well :

But I still think that hacking a wireless mouse would be the cheapest and most reliable wireless solution.

and there are cheaper than this one too.

Just take out the board from the mouse, find a good place to put this on your wheel, with the battery. Then connect up the switches on the mouse to your switches/controls. Put the mouse's small wireless usb dongle into the Joggler. Then find some Linux software that maps mouse clicks to the commands/key presses/mouse movements/whatever you want on the Joggler and your sorted. A good battery will last maybe up to 6 months. Some of the mice have a power saving feature too. These wireless mice will operate over quite a large distance.

Ok thanks for all that lot,I did come across most of those while doing my research.I've ordered and paid for a U-HID now anyway,so will have to go with that for now.The Teensy was my second choice,but would need code to be written for it which I'm utterly crap at.I've got an Arduino which I might just as well put in the bin after the total lack of any sort of support or help from the Arduino community.The chosen one has a decent GUI which really is the only option for me,I'm happy to pay the extra money for it to be this way.

I know ... but this is what happens!

How are you progressing?

Waiting for my new U-HID thingie,should be here tomorrow so will know soon enough if it'll do what I need it to do.If it does I might think about running all the steering wheel controls through it and do away with the infra-red completely.

Imagewerx; you are going into a new realm never tried thing before with the Joggler; we will learn from you.

Note that no one is using the CarPC JoyCon Exr control device today.

If you figure it all out you we can maybe create a subsection - Joggler CarPCs

Thanks Pete.I'll do a full build thread when I get time.
