    OBD with PWM protocol

    Hi everyone!!
    I am implementing an ECU simulator with PWM protocol. I had done some tests and I had been that the tester sends to ECU a start of frame (SOF) with 32us high level and 16us low lovel and then sends data. Is it correct this SOF? and to send reponses from the ECU to tester, is it the same SOF?
    And how is the end of frame (EOF)?

    Thanks you!!!

    Try to find msm6636 msm6636b_um.pdf on the net.
    There is nice explanation about pwm signals and so on.
    Both SOF are the same because both packets/directions are governed by the same rules.
