Conventions used

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

Code in text: 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: “It’s clear that the printf function is defined in a C header file, stdio.h.”

A block of code is set as follows:

#include <stdio.h>
int main()
{
    printf("Hello Cortex-M world!\n");
}

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

#include <stdio.h>
int main()
{
    printf("Hello Cortex-M world!\n");
}

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

    ./run.sh -a hello.axf

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
