Hi i am working on a formula student racing car, we have an ecu with a can output of all data. is there a way to plug the CAN Hi and CAN Lo into the Arduino and read out values to manipulate to a selection of LEDs and Seven Segement displays.
The actual programming of these is fine, its just getting the can signal into the chip so i can read it via the Tx and Rx as a string of numbers where i can bit select and use this to output the data.
I'm based in england so the reading up on the OBDuino site seems to do what i want but i needed this by yesterday.
MCP2551 and 2515 seem to be the chips to use, can anyone shed any light on these and possibly a library to use them i have found help but most sites seem to be in german or spannish and its not easy to read.
In short here i want to read a canbus register for the gear position and display on a seven segment.
I also want to read the engine RPM and light up and LED for a shift light.
Very simple things but so many examples seem to go way over what i need. All im looking for is a way to communicate with the can hi and lo of the MoTECH M800 we have.
