Hands-On RTOS with Microcontrollers - Second Edition
By :
Real-time systems come in a wide variety of implementations and use cases. This book focuses on how to use a real-time operating system (RTOS) to create real-time applications on a microcontroller unit (MCU).
In this chapter, we’ll start with an overview of what an RTOS is and get an idea of the wide range of systems that can have real-time requirements. From there, we’ll look at some of the different ways of achieving real-time performance, along with an overview of the types of systems (such as hardware, firmware, and software) that may be used. We’ll wrap up by discussing how to choose an RTOS, when it is advisable to use an RTOS in an MCU application, and when it might not be necessary at all.
For readers who are not familiar with MCUs, tutorial information on MCUs can be found in Chapter 2, Introducing the Development Board.
In a nutshell, we will cover the following topics in this chapter:
