LPC54114 FreeRTOS Low Power Modes (deep sleep and power-down)

[Erdem]

Hi all,

There are already example and application notes for LPC54114 about deep sleep and deep power-down modes for bare metal and just sleep mode for FreeRTOS.

But how can I enable deep sleep and deep power-down modes with FreeRTOS for LPC54114?

Thanks in advance!

Hello @Erdem 

Sorry there isn't there examples in official, how about refer to the code in  deep sleep and deep power down for bare metal to configure in your FreeRTOS project.

Hi @Alice_Yang,

First of all thanks for your return.

I already referred to bare metal low power modes (they work well in bare metal but not in FreeRtos) and "Using FreeRTOS tickless mode on LPC5500 (https://www.nxp.com/docs/en/application-note/AN13593.pdf ) " document. Unfortunately it does not work for LPC54114.

Do you mind sharing a working FreeRtos low power (deep sleep mode) example which is implemented on top of "LPC54114 SDK FreeRtos tickless sample"?
