C++ (Cpp) FLEXCAN0_MBn_ID Beispiele

Beispiel #1

Datei: CAN_K2X.cpp Projekt: IKharitonov/Arduino_BRT

// -------------------------------------------------------------
CAN_Frame CAN_K2X::read()
{
  unsigned long int startMillis;
  CAN_Frame msg;
  msg.timeout = CAN_TIMEOUT_T3;

  startMillis = msg.timeout ? millis() : 0;

  while ( !available() )
  {

    {
      // early EXIT nothing here
      msg.valid = false;
      return msg;
    }
    yield();
  }

  // get identifier and dlc
  msg.length = FLEXCAN_get_length(FLEXCAN0_MBn_CS(rxb));
  msg.extended = (FLEXCAN0_MBn_CS(rxb) & FLEXCAN_MB_CS_IDE) ? 1 : 0;
  msg.id  = (FLEXCAN0_MBn_ID(rxb) & FLEXCAN_MB_ID_EXT_MASK);
  if (!msg.extended)
  {
    msg.id >>= FLEXCAN_MB_ID_STD_BIT_NO;
  }
