  • Topic: Re: Arduino OBD-II UART Adapter FAQs
    You Reply: Dear Stanley,

    Could you please give us a very simple scetch including library file just to read RPM, because below code giving a lot of error.

    Here is a simplest sketch:
    [code]#include <OBD.h>

    COBD obd; /* for UART version */
    //COBDI2C obd; /* for I2C version */

    void setup()
    {
      // we'll use the debug LED as output
      pinMode(13, OUTPUT);
      // start communication with OBD-II adapter
      obd.begin();
      // initiate OBD-II connection until success
      while (!obd.init());
    }

    void loop()
    {
      int value;
      // save engine RPM in variable 'value', return true on success
      if (obd.ReadSensor(PID_RPM, value)) {
        // light on LED on Arduino board when the RPM exceeds 5000
        digitalWrite(13, value > 5000 ? HIGH : LOW);
      }
    }[/code]
