xsysmonpsv_intr_example.c File Reference

Overview

This file contains a design example using the driver functions of the System Monitor driver.

The example here shows the driver/device in intr mode to check the on-chip temperature and voltages.

Note

This examples also assumes that there is a STDIO device in the system.

int SysMonPsvIntrExample

(

)

This function runs a test on the System Monitor device using the driver APIs.

This function does the following tasks:

• Initiate the System Monitor device driver instance
• Enable OT interrupt
• Setup call back for interrupts
• Read supply configuration.
• Read the latest on-chip temperatures and confiured supplies

Returns

- XST_SUCCESS if the example has completed successfully.

• XST_FAILURE if the example has failed.
