xsysmon_polled_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 polled mode to check the on-chip temperature and voltages.

Note

The values of the on-chip temperature and the on-chip Vccaux voltage are read from the device and then the alarm thresholds are set in such a manner that the alarms occur.

    MODIFICATION HISTORY:

    Ver   Who    Date     Changes

    1.00a xd/sv  05/22/07 First release
    2.00a sdm    09/26/08 Added code to return temperature value to the main
                    function. TestappPeripheral prints the temperature
    4.00a ktn    10/22/09 Updated the example to use macros that have been
                    renamed to remove _m from the name of the macro.
    5.03a bss    04/25/13 Modified SysMonPolledExample function to set
                    Sequencer Mode as Safe mode instead of Single
                    channel mode before configuring Sequencer registers.
                    CR #703729
    7.3   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 SysMonPolledExample | ( | u16 | SysMonDeviceId,
|  | int * | Temp
| ) |  |

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

This function does the following tasks:

- Initiate the System Monitor device driver instance
- Run self-test on the device
- Setup alarms for on-chip temperature and VCCAUX
- Setup the sequence registers to continuously monitor on-chip temperature and VCCAUX
- Setup configuration registers to start the sequence
- Read latest on-chip temperature and VCCAUX, as well as their maximum and minimum values. Also check if alarm(s) are set

Parameters

  SysMonDeviceId | is the XPAR_<SYSMON_ADC_instance>_DEVICE_ID value from xparameters.h.
  Temp | is an output parameter, it is a pointer through which the current temperature value is returned to the main function.

Returns
  - XST_SUCCESS if the example has completed successfully.
  - XST_FAILURE if the example has failed.

Note
  None
