Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The C++ class itself is implemented in C as a struct containing the class variables."

A block of code is set as follows:

class B : public A { 
   // Private members. 
 
public: 
   // Additional public members. 
}; 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

class B : public A { 
   // Private members. 
 
public: 
   // Additional public members. 
}; 

Any command-line input or output is written as follows:

sudo usermod -a -G gpio user
sudo usermod -a -G i2c user

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Compared to MCUs, SoCs are not as resource-limited, usually running a full operating system (OS) such as a Linux-derived OS, VxWorks, or QNX."

Warnings or important notes appear like this.
Tips and tricks appear like this.
