Hi,
I am new to freeRTOS and am debugging some examples of freeRTOS-wsn430 using simulators WSim and WSNet.
When I was testing 05_network_device and 06_coordinator, I can successfully ready ds2411_id and treat it as MAC address
of device. But then, The program steps into preSetupTimerInterrupt() and never goes out.
int main( void )
{
/* Setup the hardware. */
prvSetupHardware();
printf(“hardware ready!\n”);
/* Create the SPI mutex */
xSPIMutex = xSemaphoreCreateMutex();
/* Create the task of the application */
vCreateMacTask(xSPIMutex, configMAX_PRIORITIES-2);
/* Add the local task */
printf(“done\n”);
xTaskCreate( vSendingTask, “sender”, configMINIMAL_STACK_SIZE, NULL, configMAX_PRIORITIES-1, NULL );
/* Start the scheduler. */
vTaskStartScheduler();
/* As the scheduler has been started we should never get here! */
return 0;
}
void vCreateMacTask(xSemaphoreHandle xSPIMutex, uint16_t usPriority) {
/* Stores the mutex handle */
xSPIM = xSPIMutex;
/* Create an Event Queue */
xEventQ = xQueueCreate(5, sizeof(uint8_t));
/* Create a Semaphore for waiting end of TX */
vSemaphoreCreateBinary( xSendingS );
/* Make sure the semaphore is taken */
xSemaphoreTake( xSendingS, 0 );
/* Create the task */
xTaskCreate( vMacTask, “MAC”, configMINIMAL_STACK_SIZE, NULL, usPriority, NULL );
// printf(“create MAC Task!”);
}
static void vMacTask(void* pvParameters) {
uint8_t event;
macState = STATE_ATTACHING;
vInitMac();
/* Network Attachment Procedure */

time = xTaskGetTickCount();

Can anybody help me please!_
