Overview

This file contains a design example using the low-level driver functions and macros of the UartLite driver (XUartLite).

Note

The user must provide a physical loopback such that data which is transmitted will be received.

int UartLiteLowLevelExample ( u32 UartliteBaseAddress )

This function does a minimal test on the UartLite device using the low-level driver macros and functions.

This function sends data and expects to receive the data through the UartLite. A physical loopback must be done by the user with the transmit and receive signals of the UartLite.

Parameters

UartliteBaseAddress is the base address of the UartLite device and is the XPAR_<UARTLITE_instance>_BASEADDR value from xparameters.h.

Returns: XST_SUCCESS if successful, XST_FAILURE if unsuccessful.

Note: None.
