Title: Simple diagnostic adaptor for KWP2000. Post by: jasnm on January 18, 2017, 01:43:06 PM Having spent many hours decoding TP2.0 and KWP2000 I built simple diagnostic adaptor using a UDOO Neo to prove it works.

Were you having troubles getting a cable to work for just diagnostics? I would imagine you were likely just either using the USB setting in your diagnostic program and you didn't have the right driver for your chip, and if you were using com port you likely didn't have your com port confgiured properly in device manager. Regardless glad you got your interface working!! :) Title: Re: Simple diagnostic adaptor for KWP2000.
