xuartlite_low_level_example.c File Reference

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.

1.00b rpm  04/25/02 First release
1.00b sv   06/13/05 Minor changes to comply to Doxygen and coding guidelines
2.00a ktn  10/20/09 Updated to use HAL processor APIs and minor changes
              for coding guidelines.
3.2   ms   01/23/17 Added xil_printf statement in main function to
                    ensure that "Successfully ran" and "Failed" strings
                    are available in all examples. This is a fix for
                    CR-965028.

int UartLiteLowLevelExample

(

UINTPTR

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

contains the base address of the device

Returns

XST_SUCCESS if successful, XST_FAILURE if unsuccessful.

Note

In XSCT/classic flow, the base address is used directly.
