Display OBD data on two screens

Post by cea97 »

Hey Guys,
I'm new to the arduino world but not new to programming. By that I mean I have some experience with c++. I would rate my skills toward the higher end of basic so I'm far from being an expert. Big picture made small, I would like to get data from the OBD2 port in my car and display different parts of that data on two separate displays. My design is something like this.

Freematics obd2 cable
|
mega2560 (master)-> 7" tft display (for speedometer and tachometer only)
|
|(These two will be "daisy chained" the 2nd arduino will recieve
| data for the 4 parameters listed below to diplay on 2nd screen)
|
mega2560 (slave)-> 4.3" tft (for oil pressure, coolant temp, volts, fuel level)

Is a setup like this possible? It seems that most of the code already exists to perform these functions. I have no intention of adding and physical input like scrolling through different screens. I only want the data to be displayed. Just looking for any advice and/or recommendations from people who know more than I do. Thanks.
