LAUNCHXL-CC1310: How to put mcu into standby mode

Gopal Agarwal

Part Number: LAUNCHXL-CC1310

Hello TI Team

I wanted to know how to put my mcu into standby mode for infinite time till any external interrupt(GPIO interrupt) wakes it up and then process the ISR and again go to standby mode for infinite time for non RTOS applications. Some examples suggest to use sleep() API for non-RTOS applications but the problem with this is I need to mention a particular amount of time in this API.

like sleep(X) // Go to stand by mode for X sec.

Thanks

Hi Gopal,

Is this question a duplicate of https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1102777/launchxl-cc1310-power-modes-api-s or are you asking for something else in this thread? I am struggling to see the differences between the two questions.

Thanks,
Nikolaj

Sir,

In this thread, I wanted to ask about sleep() API.

Hi Gopal,

Yes, you are correct, you can use the sleep() API to enter standby, and as you also correctly stated, you need specify an amount of time for this API.
You cannot use the sleep() API to go to standby mode for infinite time.

Nikolaj

I am using sleep() API in the No RTOS application to put the microcontroller into standby mode. I am using RTC to wake up the MCU from sleep periodically. But as soon as I introduce an RTC event or interrupt the program does not come out of sleep() function irrespective of the time mentioned with sleep().
The RTC will periodically wake up the MCU and after executing the RTC ISR it again goes to sleep even if the sleep time expires.

But as soon as I remove the RTC interrupt the sleep() API works fine. The program does come out after the sleep() time expires.

what can be the cause of this problem?

Hi Gopal,

Can you please try to reproduce this problem based on one of the examples in the SDK, and share it with us, so we will be able to reproduce it on our side?

Thanks,
Nikolaj
