3.4.1 EApiWDogStart
This function will start the watchdog timer using the specified parameters.
Syntax:
EApiStatus_t EAPI_CALLTYPE EApiWDogStart (
__IN uint32_t Delay,
__IN uint32_t EventTimeout,
__IN uint32_t ResetTimeout
);
Parameters
Delay: Initial delay for the watchdog timeout, in milliseconds. The first trigger must hap-
pen within (Delay + EventTimeout) milliseconds of calling EApiWDogStart.
EventTimeout: Watchdog timeout interval, in milliseconds, to trigger an event.
ResetTimeout: Watchdog timeout interval, in milliseconds, to trigger a reset.
Return value
– Status codes (EApiStatus_t)
Example (C#)
private static UInt32 EapiStatus;
//WDT is milliseconds * 1000
if (SecTimer.Checked == true)
EapiStatus = EApiWDogStart(WDTDelay * 1000, WDTEvent * 1000, WDTReset
* 1000); else if (MinTimer.Checked == true)
EapiStatus = EApiWDogStart(WDTDelay * 60000, WDTEvent * 60000,
WDTReset * 60000);
if (EapiStatus != EAPI_STATUS_SUCCESS)
MessageBox.Show(“WDog Start Error”);
3.4.2 EApiWDogTrigger
This function triggers the watchdog and resets the counter. Once the watchdog is triggered,
a system reset will not occur until the EventTimeout and ResetTimeout specified in EApiW-
DogStart() has elapsed. This is often called “petting the dog”.
Syntax:
EApiStatus_t EAPI_CALLTYPE EApiWDogTrigger ()
Parameters
None
Return value
Status codes (EApiStatus_t)
Example (C#)
private static UInt32 EapiStatus;
EapiStatus = EApiWDogTrigger();
if (EapiStatus !=EAPI_STATUS_SUCCESS)
MessageBox.Show(“WDog Trigger Error”;
