Zephyr Power Management for Wearable Devices

Explore the implementation of Zephyr Power Management subsystem for wearable devices through a smartwatch demo application based on the NXP platform. Delve into power management techniques for both device (SoC) and system levels, leveraging Zephyr kconfig symbols and devicetree features to implement various sleep modes. Learn about Zephyr's support for LVGL graphics and 2D GPU integration for smartwatch face animations. Discover how to enable specific kconfig symbols for display driver support, including MIPI display/DSI. Gain insights into power optimization techniques such as DVFS sensor and PMIC integration for core voltage reduction, as well as memory optimizations for Flash and SRAM. This 39-minute conference talk equips embedded developers with the knowledge to design low-power wearable applications using the Zephyr RTOS, presented by Disha Patil from NXP Semiconductors at a Linux Foundation event.
