Include rest of your physical dash into Realdash including the Speeduino Serial3

Reading Speeduino Secondary Serial with broader realtime dataset command "n". Then passes the data with Realdash CAN to Realdash. Testing has been done with CP21xx UART-USB adapter but should work similarly with HC-05 Bluetooth adapter.

Code is designed to use ESP32 DEVKIT V1 38PIN Board and 8 channel Optocoupler. And optocoupler is used to input dash warning lights also to the CAN protocol. But you can add what inputs you like.

This file is used by Realdash to getting it read the custom channel configuration. Just add it in Realdash -> Garage -> Connections -> Realdash CAN -> Custom Channel Description

Schematic:

This is how i have personally set it up. Polarity of the warning/indicator lights matters only in a optocoupler input side, since the boards have shared grounding on input side.

This code is based of janimm 'Realdash Arduino CAN example' and pazi88 'Serial3toBMWcan' and modified by paleppp.
