Description

This comprehensive hands-on training introduces participants to Zephyr RTOS, a scalable, real-time operating system for embedded systems.

The course covers:
Developing, configuring, debugging, and tracing Zephyr applications.
Device tree (DT) and Kconfig usage and development.
Managing threads, synchronization, memory, and interrupts in Zephyr.
Using west and writing west manifests for project management.
Zephyr kernel services, subsystems, and device drivers.
Hands-on implementation of Zephyr’s multitasking and real-time capabilities.
