CC1310: Will this put CC1310 to sleep?

Hi TI Team,

If I create a thread and it's just a while loop with Task_sleep(sleep_time) function in it, will that put the controller to sleep? Will the controller wake up every sleep_time?

void* mainThread(void *arg0)
{
    while(1)
    {
        Task_sleep(sleep_time);
    }
}

I also noticed when I remove the Task_sleep in the while loop, the power consumption will be quite high. How does TI RTOS know if the controller is idle and should be put to sleep?

Thanks,

Hi OG,

Given that you are using TI RTOS, and inferring that this is the only thread you are running on your chip, that will indeed but the device to sleep.

You can verify that the device wakes up or not using our EnergyTrace tool, if you have any doubt.

Regards,

Arthur

Thanks Arthur!

How about a while loop without Task_sleep()? I noticed that it won't be put to sleep mode, but the controller is doing nothing, so should it be put to sleep mode instead?

void* mainThread(void *arg0)
{
    while(1)
    {

    }
}

Hi OG,

Indeed, the code you have shared will keep the device active, as we haven't told it that is is allowed to sleep through the Task_sleep() call.

Usually, it is better to try to use the less amount of power possible, so Task_sleep should be used here.

Arthur
