Description

+

In most applications, threads need to communicate with each other or access shared resources together. There are many ways to exchange data between threads, for example using shared data, polling loops and message passing.

+

Many resources in a microcontroller can be considered as serially-reusable. This means that they can be used repeatedly by different threads, but only by one thread at a time (for example communication peripherals such as UARTs, memory, and files that need to be modified).

+

The CMSIS-RTOS API provides different means to pass messages between threads to make inter-thread communication more efficient. Also, resource sharing is inherently supported. The following methods are available to the user:
