First of all, sorry to beat a dead horse, but I am planning on running Realdash on a RPI4 for a car that does not have a canbus. Everything is going into a 1996 Chevy Caprice, LS Swapped using stock pcm, connected to realdash using OBDLink SX. I’ve got most everything figured out, but the last part I am trying to complete is to get these last few items to work for me. I want to add turn signal indicators, fuel level, and shifter position to the dash.
I do know that I’d have to either use the GPIO’s on the RPI or use an arduino. For the turn signals, I know that I’d probably need something like a voltage divider circuit. For the fuel level, I’d probably need some type of device to convert ohms to the Pi. I’m not sure what I would need for the shifter position, but honestly, that’s the least of my concern, but I would love for it to work.
I wuld get a cheap esp32, and then connect the signals via some level shifters and sending to real dash via Bluetooth. I’m dooing that with my LT swapped ranchero for fuel level and some misc.
You can pull that code and use it as you wish.
A pi is exspensive to replace if for some reason it gets 12v, where a esp is like a few $ max
Okay, so I see it mentions like fuel level in the write up, what about turn signals, how would that work since it would be 12v from the stock wiring going to realdash
just a typo. im using it with raspberry
