int CanPsPolledExample

(

u16

DeviceId

)

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

DeviceId

is the XPAR_<CANPS_instance>_DEVICE_ID value from xparameters.h

Returns

XST_SUCCESS if successful, otherwise driver-specific error code.

Note

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