Example

byte brakePedalActive(long channel, longdir, longradioChannel, long signalStrength, long sigQuality, long packet)
{
  byte accelerationControl[1];

  if (C2xGetTokenBitString(packet, "CAM", "cam.camParameters.highFrequencyContainer.basicVehicleContainerHighFrequency.accelerationControl", 7, accelerationControl))
  {
    return accelerationControl[0] & 0x80;
  }
  return 0;
