I connected the canbus shield V2 to the car through the OBD2 interface then to Arduino Uno.
try one of seeed’s examples in its library and give me no results, just say the connection is ok on the serial monitor.
can anyone help me? do I need a special code for using OBD2 instead of just that two wires?
What model of car are you testing? What is the communication speed of OBD-II’s CAN bus?
oh please, I really need help, nothing works!!
The example code “receive_monitor” works for me, I receive a lot of messages from OBD2 port.
But I want to hook up the CANHacker SW to the serial data (USB Port) but I do not find any example that support my setup.
