I want to try and read the data from the engine OBD and out put eventually in Arudino. I'm new to some big parts of this project, so seeking for some help. I found this post, which shows how to connect a COM cable to the DLC1 connector on the car in order to use there s/w: http://www.microsofttranslator.com/bv.aspx?from=&to=en&a=http://primavistalab.com/myengine/
I have a MCP220 USB to Serial break-board that I checked that there s/w recognise.
My Q is: how do I wire the CABLE to the MCP2200 ?
Also, he mentions in the instructions of the s/w that u should not use a laptop but a grounded computer? I do not have a desktop that I can use , can I ground some other section with a rode to the floor- or something like that ?
Thanks in advance.
