Hi, I'm using a XMC4108 processor and want to generate an interrupt when I receive CAN RTR frames. I have this working, but for some reason I need to constantly set the DIR bit of the CAN receive Object or it will reset on its own almost immediately after setting it. I am using CAN_NODE_MO_ClearStatus(HandlePtr1->lmobj_ptr[2], XMC_CAN_MO_SET_STATUS_RX_ENABLE | XMC_CAN_MO_SET_STATUS_MESSAGE_DIRECTION); to set the DIR pin, am I doing that correctly or is there a better more correct way of doing it so I don't to make the call over and over?

 

Thanks, Rob

We are trying to use the virtual COM port with Windows on an XMC4400 Eval board.

Basically we added the USBD_VCOM module in DAVE, and tried many different things in main function, but all with same result.

The processor just hangs in the while(!USBD_VCOM_IsEnumDone()), so USB is never enumerated.

Windows shows a device but after a few seconds Windows reports "Device descriptor request failed".

What could be wrong ?

	status = DAVE_Init();
	if (status == DAVE_STATUS_FAILURE)
	{
		XMC_DEBUG(("DAVE Apps initialization failed with status %d\n", status));
		while (1U){
		}
	}


	if(USBD_VCOM_Connect() != USBD_VCOM_STATUS_SUCCESS)
	{
		return -1;
	}

	while(!USBD_VCOM_IsEnumDone());

Hi,

 

I have a XMC45 Relax Kit and I need to know how to implement Ethernet_Client (UDP, TCP does not matter) communication in ModusToolBox with BSP library. 

My target is to control some digital outputs from Ethernet communication via a PC(as a server) to send a command through Ethernet and controlling I/O of XMC.

 

In addition, I do not know why, when I am creating new application in ModusToolBox with XMC45 Relax kit, "cyhal.h" library is not recognized?

 

I will be thankful if somebody can help me with a source or samples regarding that implementation.

Best regards,

Mo
