hello sir
i am working on cc1350 launchpad . and i have implemented the watchdog timer for my application
my question is that , when my watchdog has been reset. after time overflow. it will stuck somewhere . i when i press the button it will start. but second time after the time overflow. it is not stuck it will reset automatically.
just i need press the reset button first time. after program has been flashed.
i dont understand why it is happening , i am attaching my code below please check it.
void *mainThread(void *arg0)
{
unsigned char i=0;
Watchdog_Params params;
/* Call driver init functions */
GPIO_init();
Watchdog_init();
/* Configure the LED and button pins */
GPIO_setConfig(Board_GPIO_LED0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
GPIO_setConfig(Board_GPIO_BUTTON0, GPIO_CFG_IN_PU | GPIO_CFG_IN_INT_FALLING);
/* Turn off user LED */
GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_ON);
GPIO_write(Board_GPIO_LED1, Board_GPIO_LED_ON);
sleep(5);
/* Create and enable a Watchdog with resets disabled */
Watchdog_Params_init(¶ms);
params.callbackFxn = NULL;
params.resetMode = Watchdog_RESET_ON;
watchdogHandle = Watchdog_open(Board_WATCHDOG0, ¶ms);
if (watchdogHandle == NULL)
{
/* Error opening Watchdog */
while (1);
}
Watchdog_setReload(watchdogHandle, 3000000);
/* Enter continous loop */
while (true)
{
i++;
Watchdog_clear(watchdogHandle);
GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_OFF);
GPIO_write(Board_GPIO_LED1, Board_GPIO_LED_OFF);
sleep(1);
GPIO_write(Board_GPIO_LED0, Board_GPIO_LED_ON);
GPIO_write(Board_GPIO_LED1, Board_GPIO_LED_ON);
sleep(1);
if(i>10)
{
i=0;
while(1);
}
}
}
