Include dependency graph for wdt.h:

Macros
#define	NWDT_TIME_LOWER_LIMIT
	Lower limit in ms for wdt operating in NORMAL mode.

#define	NWDT_TIME_UPPER_LIMIT
	Upper limit in ms for wdt operating in NORMAL mode.

#define	WWDT_TIME_LOWER_LIMIT
	Lower limit in ms for wdt operating in WINDOW mode.

#define	WWDT_TIME_UPPER_LIMIT
	Upper limit in ms for wdt operating in WINDOW mode.

#define	WDT_HAS_STOP (0)
	Set to 1 if the platform supports wdt_stop(), 0 otherwise.

#define	WDT_HAS_INIT (0)
	Set to 1 if the platform implements wdt_init(), 0 otherwise.

#define	CONFIG_PERIPH_WDT_WIN_MIN_MS (0)
	If `periph_wdt_auto_start` is used, this will be the lower bound of when the WDT can be kicked.

#define	CONFIG_PERIPH_WDT_WIN_MAX_MS (1024)
	If `periph_wdt_auto_start` is used, this will be the max period after which the WDT must be kicked or else it will reboot the system.

#define	CONFIG_WDT_WARNING_PERIOD (1)
	Period (ms) before reboot where wdt_cb() is executed.

Typedefs
typedef void(*	wdt_cb_t) (void *arg)
	Signature for the watchdog early warning callback.

Functions
void	wdt_start (void)
	Start watchdog timer.

void	wdt_stop (void)
	Stop watchdog timer.

void	wdt_kick (void)
	Reset the watchdog timer counter, delay system reset.

void	wdt_setup_reboot (uint32_t min_time, uint32_t max_time)
	Set up the wdt timer.

void	wdt_init (void)
	Initialize WDT module.

void	wdt_setup_reboot_with_callback (uint32_t min_time, uint32_t max_time, wdt_cb_t wdt_cb, void *arg)
	Set up the wdt timer with callback.
