Diagnostic display

Post by Jmx3000 »

Hi guys.
First, this is an awesome device and site! I have been looking for weeks for a similar device for my project.
My plans are, to build the datalogger but....
The main question I have is, can this be made to read serial data from diagnostic port? I have the signal protocol for most of the data stream.
I dont know the first thing about coding nor how it is implemented however, I have found an algorithm for decoding the serial stream.
I also have come across the wiring diagram for the data cable
This is for an obd 1 toyota for which there is zero datalogger support.
Any help would be greatly appreciated!
Thanks

Hi,

yes, thats possible. The Arduino Mega has enough serial ports to read data from an ecu over k-line.
I have a similar goal on my roadmap: read data from a Digifant I ecu (non-obd, I'll have to implement my own serial protocol) and later read data from obd ecus over KWP-1281 protocol.
