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.
