I had the same error.

You need to copy OBD.h and OBD.cpp to the libraries root directory, not in the source folder!

IE: ProgramFiles(x86)]\Arduino\libraries\OBD.h
IE: ProgramFiles(x86)]\Arduino\libraries\OBD.cpp

I tried other Example programs and nothing seems to work. I tried uninstalling and re-installing the Arduino IDK and the Freematics GITHUB files. The error I'm receiving is: obd_uart_test.ino:10:22: fatal error: OBD2UART.h: No such file or directory compilation terminated. Error compiling. or obd_ua...

RE: #2 I suspect this has to do with the orientation of the OBDII port in your vehicle and whether the Freematics dongle is 'phased' properly. Some code will need to be written to calibrate the x, y, z axis with respect to the port. For instance in one of my vehicles the port allows the Freematics d...

You can send the 0100 request which will produce a response from the PCM/ECU.

I'm not sure that it's a supported PID:

https://en.wikipedia.org/wiki/OBD-II_PIDs

I believe the code that you are showing is a DTC code, not a CAN bus PID from the sensor?

Please correct me if I'm wrong as I'd be interested in knowing if an update has been made in the protocol.

Hello Everyone, I recently purchased a Freematics ONE (OBD-II) Adapter that connects to serial TX1/RX1 of the Arduino Mega. I'm trying to make the code work with the Arduino Serial monitor because I do not have an LCD. I'd like to simply use my laptop as the dispLAY. The following is my code and the...
