TX ERROR ID=0x200 似乎是正確的,但資料都是空空的
int main(void)
{
    
CAN_MSG_OBJ msg;
    
uint8_t data[8] = {0x41,0x42,0x43,0x44,0x45,0x46,0x47,0x48};

    
// initialize the device
    
SYSTEM_Initialize();
    
CAN1_TransmitEnable();
    
//CAN1_ReceiveEnable();
    
while (1)
    {   
        
// Add your application code
        
CAN1_OperationModeSet(CAN_CONFIGURATION_MODE);

        if(
CAN_CONFIGURATION_MODE == CAN1_OperationModeGet())
        {
            if(
CAN_OP_MODE_REQUEST_SUCCESS == CAN1_OperationModeSet(CAN_NORMAL_2_0_MODE))
            {
