Detailed Description

Defines a driver for the watchdog interface.

This driver manages the hardware watchdog countdown timer. When enabled, the watchdog timer will generate an interrupt when the timer counts down to zero, then will reload the counter. If the counter counts down to zero again, the hardware performs a device reset. The lowest priority "idle" thread restarts the watchdog counter preiodically, and other operations that may keep the system busy call wiced_hal_wdog_restart to extend the watchdog countdown.

Macro Definition Documentation

#define wiced_hal_watchdog_disable   wiced_hal_wdog_disable

Disable the system watchdog.

Useful for debugging when the watchdog would interfere and reset the system when not desired (e.g. when the system is connected to a debugger, etc).

NOTE: This is for debugging purposes only. Hence, there is no complementary "Enable Watchdog" function. Please do not use this function in production applications.

Parameters

none

Returns

none

#define wiced_hal_watchdog_reset_system   wiced_hal_wdog_reset_system

Execute a soft reset of the system.

Parameters

none

Returns

none

#define wiced_hal_watchdog_restart   wiced_hal_wdog_restart

Restart the watchdog (restart the watchdog's internal timer).

Used to manually "pet" the watchdog when certain processes might otherwise cause the watchdog to trigger and reset the system. The default timeout for watchdog reset is two seconds.

Parameters

none

Returns

none
