I am facing a problem. I have two devices.(one device sending pkt at 200 hz and other at 50 hz) . If I trun on only one device it works fine but if i turn on both together then one(50Hz) get hanged up and stop sending data. Now I want to use watchdog timer to reset that device automatically but I do not have any good idea how can I did that…please guide me how can I use watchdog timer to get rid of this problem or any other solution.
Thx in advance.
Sorry, I do not understand the situation you described. You said you have two devices. Do you mean you are using two MSP430 chips? If so, are they interacting with each other?
I think it is better to fix a bug than to hide the bug. Using the watchdog to reset is usually used as a safety net to catch unexpected bugs. It is not good to use it to hide known bugs. It does not fix the bug.
yes I have two msp430 chips intergrated with radio module of zigbee. (CC2420)…
I agree with you and wants to fix the bug…the sample code is as follow.
please let me knw if still its not clear.thx
int main( void )
{
bus_init(); /* Initialize hardware */
LED_INIT();
/* Start debug library at 115.2 kbps */
/* Initialize Stack */
// Create FreeRTOS Tasks, slightly higher priority to the normal task
// Start the FreeRTOS Scheduler
vTaskStartScheduler();
return 0;
}
static void vtest( void *pvParameters )
{
portTickType xLastWakeTime;
xLastWakeTime = xTaskGetTickCount();
vTaskDelayUntil(&xLastWakeTime, 1000 / portTICK_RATE_MS );
//create and open socket
for (;
{
// allocate buffer
//reading adc values and put in the buffer after that send them
}
}
