Been doing quite a bit of searching lately on this topic. Stumbled on several diy methods. Thinking nextion displays with one of the Arduino controllers. Don't know which would be appropriate or if I need two based off what I want to do.
The first important thing to mention is my guage cluster has dedicated signal wires not can data. I have a set of analog gauges but are a bit old school for an 01 car. I'm considering one large tach with 2 nextion displays on either side one acting bad a digital speedo/odemeter info center and the other be a oil pressure, water temp, voltage, and fuel level.
Seen versions of this done, but had several questions about boot time and capability of live streaming the above parameters in real time. And which hardware would be best suited.
This is my first entry into this type of project, but for the day job I configure and build DAQ systems soninhave experience converting signals into usable data. Just not on this platform
