Chapter 23
Multitasking
Abstract
This chapter introduces the concept of multiple concurrent tasks in a single processor. An overview of the different kinds of operating systems is presented with advantages and disadvantages of each on a PIC® microcontroller.
A deterministic dispatcher type of real-time operating system (RTOS) is used for the example programs. The primitive RTOS function calls in C are all taught in this chapter, with examples of their proper use. Data passing between tasks and sharing global data in a safe fashion are covered in this chapter.
Examples and exercises are for the popular PIC® microcontroller manufactured by Microchip.
