I have put an 3.5inch tft in my dashboard.

Hi, that is nice, but isn't the sense of a forum to put the information there instead of using it as link farm?

You are invited to use the "Datei auswählen" button below to upload your things.

I thought a link is better because this doesn't take resources on the server.
And there is a button to add an imaga as a link so... ?

but attached foto and arduino code.

Looks very nice, which information do/can you show on your TFT?

Best, Rainer

I can show everything which i would if i know what all can-bus messages mean.
At this moment i show:
km's the car has driven
time
coolant temp
oil temp
turbo pressure
fuel status
rpm
speed

Hello,

Which can-bus shield do you use? It has 2 can interfaces or only one?

Thanks
