The Common Microcontroller Software Interface Standard (CMSIS)
In this chapter, we will delve into the Common Microcontroller Software Interface Standard (CMSIS), a critical framework for Cortex-M and some Cortex-A processors. We will begin by learning how to define hardware registers using C structures. This foundational knowledge will enable us to read and understand CMSIS-compliant header files provided by microcontroller manufacturers.
Next, we will explore CMSIS itself, discussing its components and how it facilitates efficient software development. Finally, we will set up the necessary header files from our silicon manufacturer, demonstrating how CMSIS compliance can streamline production and improve code portability.
In this chapter, we’re going to cover the following main topics:
- Defining peripheral registers with C structures
- Understanding CMSIS
- Setting up the required CMSIS files
By the end of this chapter, you will be equipped with a solid...
