J&W / WatchDogK64F

WatchDog with generalization and specialization for Freescale FRDM K64F. Tested and working - also in multi-threaded environment.

Watchdog with generalization and specialization for Freescale K64F Tested on the FRDM K64F from Freescale Can be specialized for any type of the processor as long as one watchdog kicker exists only

Based on hints from https://os.mbed.com/users/manitou/code/k64f_wdog/ but reworked.

Usage:

1. include "mbed.h"
2. include "WatchDog.h"

WatchDog WatchDog wd;

int main(void) { wd.Start(1000); Watchdog 1000ms

printf("\r\nON - restart %d cause %4X\n\r", wd.RestartCounter(), (int)wd.RestartCause());

while(wd.RestartCounter()<10) { ThisThread::sleep_for(200); wait(200ms) wd.Kick(); we kick the watchdog to not die if not error. On Error (or when we are not getting time from other threads) then restart. }

wd.Stop();

printf("\r\nOFF! %d restarts \n\r", wd.RestartCounter());

return 0; }
