Hello everyone!
I have to read data control from a car,I use this shield:
http://www.skpang.co.uk/catalog/arduino-canbus-shield-with-usd-card-holder-p- 706.html
Can anybody help me?
I honestly do not know what to do, apart from the wiring, I think I've done correctly, I do not know how to move.
The data that I know are:
The unit consists of a balanced 2-wire (Canh and CANL),standard ISO 11898-2, reading speed 1 Mbps.
I tried to run the code supplied by the seller of the link above, but can not display any information.
My goal is to display much information as possible:
speed, rpm, temperature, etc..
I hope that someone can help me,
Thank you.
