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.
I created an example from sdk for freertos tickless mode, it runs well for sleep mode but not deep sleep and deep power-down.
How can I enable deep sleep and deep power-down modes with FreeRTOS for LPC54114?
Thanks in advance!
Hi,
Thanks for the reply. I already tried it with the given information in the AN13593 document but it does not work for LPC54114. Do you have any chance to create a simple "FreeRtos tickless deep sleep mode example for the LPCXpresso54114 board" ?
Hi,
Pls refer to the application note AN13593.pdf for freertos low power mode, it has the sleep mode, deep sleep mode examples. For the deep power-down mode, because the LPC will reset from deep power-down mode after waking-up, it is okay to just enter deep power-down mode and enable the RTC... which can wake-up the lpc from deep power-down mode.

Hope it can help you
