History

Andy Ross f288d1e4a7 tests: samples: Apps shouldn't set tick rate Tick rate is becoming a platform tunable in the tickless world. Some apps were setting it due to requirements of drivers or subsystems (or sometimes for reasons that don't make much sense), but the dependency goes the other way around now: board/soc/arch level code is responsible for setting tick rates that work with their devices. A few tests still use hard-configured tick rates, as they have baked-in assumptions (like e.g. "a tick will be longer than a millisecond") that need to be addressed first.

Synchronization using CMSI RTOS V1 APIs
#######################################

Overview
********
The sample project illustrates usage of timers and message queues using
CMSIS RTOS V1 APIs.

The main thread creates a preemptive thread which writes message to message queue
and on timer expiry, message is read by main thread.


Building and Running Project
****************************
This project outputs to the console.  It can be built and executed
on QEMU as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/philosophers
