xuartpsv_polled_example.c File Reference

Overview

This example runs on versal evaluation board (vck190), it sends data and expects to receive the same data through the device using the local loopback mode in polled mode by using XUartPsv driver.

Note

If the device does not work properly, the example may hang.

int UartPsvPolledExample

(

u16

DeviceId

)

This function does a minimal test on the UartPsv device and driver as a design example.

The purpose of this function is to illustrate how to use the XUartPsv driver.

This function does a minimal test on the XUartPs device in polled mode. This function sends data and expects to receive the same data through the device using the local loopback mode.

Parameters

DeviceId

is the device Id of the UART device and is typically XPAR_<UartPsv_instance>_DEVICE_ID value from xparameters.h.

Returns

XST_SUCCESS if successful, otherwise XST_FAILURE.

Note

This function polls the UART, it may hang if the hardware is not working correctly.
