Function Documentation

int CanPsPolledExample	(	XCanPs *	CanInstancePtr,
		UINTPTR	BaseAddress
	)

The entry point for showing the XCanPs driver in polled mode.

The example configures the device for internal loop back mode, then sends a Can frame, receives the same Can frame, and verifies the frame contents.

Parameters

BaseAddress

contains the base address of the device

Returns

XST_SUCCESS if successful, otherwise driver-specific error code.

Note

- In XSCT/classic flow, DeviceId is used to look up the device configuration.

• If the device is not working correctly, this function may enter an infinite loop and will never return to the caller.
