xsysmonpsu_single_ch_intr_example.c File Reference

Overview

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

This example here shows the usage of the driver/device in single channel interrupt mode to handle End of Conversion (EOC) and VCCINT alarm interrupts.

Note

This code assumes that no Operating System is being used.

The value of the on-chip Vccint voltage is read from the device and then the alarm thresholds are set in such a manner that the alarm occurs.

Function Documentation

int main

(

void

)

Main function that invokes the Single Channel Interrupt example.

Parameters

None.

Returns

• XST_SUCCESS if the example has completed successfully.
• XST_FAILURE if the example has failed.

Note

None.

References SysMonPsuSingleChannelIntrExample().

int SysMonPsuSingleChannelIntrExample	(	XScuGic *	XScuGicInstancePtr,
		XSysMonPsu *	SysMonInstPtr,
		u32	SysMonDeviceId,
		u16	SysMonIntrId
	)

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

The function does the following tasks:

• Initiate the System Monitor device driver instance
• Run self-test on the device
• Reset the device
• Set up alarm for VCCINT
• Set up the configuration registers for single channel continuous mode for VCCINT channel
• Setup interrupt system
• Enable interrupts
• Wait until the VCCINT alarm interrupt occurs

Parameters

XScuGicInstancePtr	is a pointer to the Interrupt Controller driver Instance.
SysMonInstPtr	is a pointer to the XSysMon driver Instance.
SysMonDeviceId	is the XPAR_<SYSMON_instance>_DEVICE_ID value from xparameters.h.
SysMonIntrId	is XPAR_<SYSMON_instance>_VEC_ID value from xparameters_ps.h

Returns

• XST_SUCCESS if the example has completed successfully.
• XST_FAILURE if the example has failed.

Note

This function may never return if no interrupt occurs.
