Arduino Version- Update 2015: I developed an Arduino OBD reader for the older OBD KW1281 protocol: • An OBD USB adapter (USB KKL adapter ‘‘) was hacked, so I could connect the car OBD to the Arduino (TX/RX via software serial). • An Arduino LCD display (‘YwRobot LCMI602 IIC V1’) was attached to the Arduino. • Arduino code was written for the KW1281 protocol to read car sensor data (RPM, oil/coolant temperature, throttle, air, etc.) and show them on the display. Thanks for the code and the info! I’m trying to use the project to use the “read blocks” part but with a ELM327 bluetooth adapter and a STM32 board running arduino code (STM32duino).
I’m able to read the engine module with other library (OBD) but this one was failing. Sygic Gps Maps Download For Windows Certification more. I found that, as I wasn’t using the RX/TX lines directly, I wasn’t able to do the “slow init”. As a workaround I tried to use the AT command “AT IIA xx” to do this but the BT adapter is a clone 🙂 and it doesn’t support this command. I’m going to gut the adapter and access the lines directly (on level converter) as you are doing Thanks again! Hello, thank you all for sharing your code and the development on this nice project. I have transformed an 2L engine of a Golf 3 (AGG) to a VW bus (T3) and get a lot of sensor data on a little display with this code. The ECU system is the Simos 4.
