Detailed Description

Routines to set and kick the Watchdog timer for the K64F.

User inputs a value from 1 to 356 seconds when initializing the Watchdog timer. The user's input number is multiplied by a fixed value and then placed into the countdown timer.

The user is responsible for "kicking" the Watchdog before the timeout interval expires, otherwise the K64F will automatically reboot.

 #include "mbed.h"
 #include "Watchdog.h" 

 Watchdog wdt;

 int main() {
     //initialization code....
     wdt.kick(20);           //init the watchdog for a 20 second timeout
     while(1) {
         wait_ms(1000);      //do some code
         wdt.kick();         //kick the watchdog before 20 seconds is up
     }
 }
