Implement the low power support in FreeRTOS

[kein_sunion]

Hello everyone,

I have an existing FreeRTOS project designed for a power-saving application, and I am preparing to migrate it to a new IC, the MCXC141.

In the old project, setting configUSE_TICKLESS_IDLE to 1 allowed the system to enter low power mode when tasks were idle, and the low power support feature provided by the manufacturer.

Here is a couple of questions:

• Can I simply set configUSE_TICKLESS_IDLE to 1 to enable low power support on the new IC or the only way is implemented by myself?
• Are there any other methods to achieve low power support?

Thank you for your help!

hi,kein_sunion

The MCX C144 microcontroller are ideal for embedded applications that require low power consumption, flexibility, and cost effectiveness. It has multiple low-power modes, which need to be selected and configured according to specific needs.

The questions you raise are suggested in the introduction linked below.

Note about the source code in the document (nxp.com)

This link explains The MCXC444 microcontroller family provides an explanation ultra-low-power feature for the power sensitive market. This MCU family implements several low-power modes to meet this  requirement. The application note provides detailed information about each power mode and includes case examples in the  SDK power mode switch example demo.

Hope it can help you.
