So the bus computer is what sends all the info to your display? If you have no computer in your bus is that kind of display an option at all?

Update - I parsed more PGNs and now have my throttle and engine load as well as parsed the transmission responding back to the ECM with its status.
I'm still working on processing cruise status.

You don't fool around !!!

In your code, you have many lines that start with #. How do you expect job security by commenting code?

yeah in my case the Engine comuter operates one display, and the transmission computer operates the other...

without a computer in your bus you can install analog sensors for say water temp , trans temp, oil pressure, pickup a tach signal and speed signal by sharing into the wires for the existing dash gauges.. and then running them into something like an Arduino or Raspberry PI with an accessory analog input board on it and then you could dsplay to a screen.

To see what is on the display you would have to make a light box.
Just thinking out of the box.

this sounds like fun!!! so the LCD panel itself in the TV is actually flexible? and all I really need is a backlight and a protective lense? so those fancy curved monitors and TV's arre really nothing special??

Can the pi also then run lighting, stereo and the such? If so are these downloadable programs or do they need to be written by a wiz like you Christopher?

I love the idea of automation. As well as creating a unique thing.

Just did a quick google on the pi. One thing was hook it to speakers and have streaming music now I'm sold. Is there a place i can send something like that too, for programming?

I think there are people running KODI for their media centers on the PI.. I havent gotten that far yet.. thus far my music has been my phone or tablet to a pair of linked JBL Bluetooth speakers...

running lights and such.. you can use a simple USB relay board to do it.. there may be canned software you can get.. I bought a box of those relay boards.. thus far ive only used one (a master return damper control in my house) and it works good.. I wrote the software to drive it on the pi.....

the plan is to have a second Pi in my bus as my virtual switch panel for heaters / Air-con, lights, etc... I really dont like my current blue-bird dash / switch panel.. I like the older body style better.. nowhere to put A/C vents on my dash in this one.. so im going to reqork all of that up front where I can have A/C vents.. ie get rid of mny of the hard switches and a 7 inch screen instead.. gives me room for A/C vents across the top of my switch panel.
