Public Functions Documentation

function syn_hwwdt_feed

Feed (reload) the hardware watchdog counter.

void syn_hwwdt_feed (
    void
) 

Call this function from your main loop or scheduler idle hook to prevent the hardware from resetting the system.

---

function syn_hwwdt_init

Start the hardware watchdog with the given timeout.

SYN_Status syn_hwwdt_init (
    uint32_t timeout_ms
) 

On most MCUs the watchdog cannot be disabled once started. syn_hwwdt_feed() must be called more frequently than timeout_ms.

Parameters:

• timeout_ms Desired timeout in milliseconds.

Returns:

SYN_OK on success, SYN_ERROR if the hardware WDT cannot be started.
