All three transceiver IC's worked without problems when the typical application circuit from the datasheet was used. The code has been developed using Teensy 3, the K-line transceiver IC's used were during the development were the MC33290, SN65HVDA100 and SN65HVDA195. ![]() Additionally a second class has been created which can simulate responses for testing purposes. ![]() The goal of the library is to provide a simple class which handles the communication with the port. This makes it hard to extract the communication parts for use in another project. ![]() However, I found that most of these projects either use an ELM327 chip or the communication code is interwoven with the rest of the program. There are numerous projects which read data from the diagnostic port and display or record this. This is a library to read data from the OBD-II port through the K-line pin using either ISO 9141-2 or ISO 14230-2 (KWP).
