A simple application that demonstrates basic sanity of the kernel. Two threads (A and B) take turns printing a greeting message to the console, and use sleep requests and semaphores to control the rate at which messages are generated. This demonstrates that kernel scheduling, communication, and timing are operating correctly.
This project outputs to the console. It can be built and executed on QEMU as follows:
.. zephyr-app-commands:: :zephyr-app: samples/synchronization :host-os: unix :board: qemu_x86 :goals: run :compact:
threadA: Hello World!
threadB: Hello World!
threadA: Hello World!
threadB: Hello World!
threadA: Hello World!
threadB: Hello World!
