OBD9141 | A class to read an ISO 9141-2 port found in OBD-II ports

OBD9141 is a C++ library. OBD9141 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a library to read data from the [OBD-II][obd2] port through the K-line pin using either ISO 9141-2 or ISO 14230-2 (KWP). There are numerous projects which read data from the diagnostic port and display or record this. 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. This makes it hard to extract the communication parts for use in another project. The goal of the library is to provide a simple class which handles the communication with the port. Additionally a second class has been created which can simulate responses for testing purposes.
