Re: Arduino CAN Colour Dash Display

Hi,
It's a pretty simple science when communicating with the display, both the Nextion and 4D displays have Arduino libraries freely available.
- https://github.com/bborncr/nextion
- https://github.com/4dsystems/ViSi-Genie-Arduino-Library
You basically create the controls inside either the Nextion or 4D systems development environment software, then send values over a serial connection to those controls.
I'm fairly handy in photoshop, and have an eye for good UI (or so I think), I quite enjoy designing the displays look and feel. I believe my designs are a step up from what you'd normally see in a home brew display (Just take a look on YouTube at what others have done).
There are some really cool looking displays for racing Sims, they use a similar technology, but rather than displaying values from an ECU using CAN. They just display values from a game using Serial. SimHub is the software tool people seem to use, I have no experience of using it, but my hours of research lead me down that path.
As for my project, I'd hoped to have updated this thread a little sooner, but getting the rev counter working at a acceptable speed has been very challenging. I'm getting close to a point where I'm happy with how it works, so hopefully I'll get an update out in the next few days.
I've been busy labeling and removing all the wiring from my car this weekend. Now I'm happy with the basics of the dash, I need to prioritise getting the car to a running state to do some proper testing.
