I used the sketch attached to log DATA from CAN BUS device failed, what can be?
Thanks

INT32U canId = 0x000;

Serial.begin(115200);
//// Serial.begin(38400); //// MDF1 [38400 / 9600 ]
START_INIT:
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<len; i++)
{
Serial.print(buf[i]);Serial.print(",");
}
Serial.print(">");
Serial.println();
}
}
