K81 Sample Code, enter to LLS state and exit through an LLWU interrupt.

[moises_reyes]

Hi,

I am trying to send my board to LLS state ( basically i want to just turn off everything) and then i want to wake it up using an LLWU interrupt.
Do you have a sample code to achieve that?

I am using MCUXpresso IDE v10.2.0_759 and SDK_2.4.0_TWR-K81F150M.

Thanks.

Hi,

it seems like a very complete example, but have you a sample code where FreeRTOS is also used?

I have read that there is a precise course of action, to shut down the FreeRTOS tasks and then continue with the internal processor.

That is what i am looking for.

PS: sorry, i didn't give all the info in my first question.

Thanks !!!

Hi,

There is a quite similar demo named "freertos_tickless", which shows the CPU enter at sleep mode and then
it is waked up by expired time delay that using LPTMR module.

You could find this demo with below path:

..\TWR-K81F150M\boards\twrk81f150m\rtos_examples\freertos_tickless

Have a great day,
Mike
