I am thinking one vTask control by two binary semaphores, I am not sure how to do it properly. Say one is RTCSemaphore, another is UartSemaphore, both are given from ISR. Any ISR will trigger vTask from block state to running state. Here is my idea, is there some better way to do it?
vTask(void *pVParameters)
{
for(;
{
  if(xSemaphoreTake( RTCSemaphore, portMAX_DELAY) == pdTRUE)
   {
        DoRTCProcess(…);
    }
    else if(xSemaphoreTake( UARTSemaphore, portMAX_DELAY) == pdTRUE)
   {
       ProcessUartData(…);
    }
}
}
