Salut les amis

Alors en mode construction du simulateur CAN suite à l'injection du code dans le microcontrôleur Atmega328 "arduino" j'obtiens une erreur avec (INT32U canId = 0x000;) ouaiii super, je ne l'attendait pas celui là :)

Donc premier sujet à traiter, j'ai installer plusieurs library afin d'être tranquille mais cette erreur m'etais inatendu, bref je vais faire des recherches pour surmonter cet obstacle. Voici le setch...

//This Arduino UNO Sketch requires the Seeed CAN-BUS Shield Libraries

if(CAN_OK == CAN.begin(CAN_500KBPS))
{
Serial.println("CAN BUS Shield init ok!");
}
else
{
Serial.println("CAN BUS Shield init fail");
Serial.println("Init CAN BUS Shield again");
delay(100);
goto START_INIT;
}
}
void loop()

if(CAN_MSGAVAIL == CAN.checkReceive())
{

CAN.readMsgBuf(&len, buf);
canId = CAN.getCanId();
Serial.print("<");Serial.print(canId);Serial.print (",");
for(int i = 0; i
BuildMessage="";
}

}

Ok, je passe à la recherche de ce qui pourrait causer cette erreur et partagerais le résultat.
