To get the most out of this book

Every effort has been made to make working through the examples in this book as easy as possible for a very wide range of people. To get the most out of the book (by working through the examples), you'll need the following hardware:

• A Windows, macOS, or Linux PC with internet access
• An STM32 Nucleo-F767ZI development board
• Two Micro-USB cables
• Jumper wires—20 to 22 AWG (~0.65 mm) solid core wire

Detailed setup instructions for the different tools used are included in the chapters.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

Since this book targets programming low-level embedded systems, we'll be using C as the language of choice. Some knowledge of microcontrollers is assumed, as is the ability to read a datasheet. If you have a good understanding of the C language (or C++), then you should be comfortable reading this book – no previous RTOS knowledge is required. Since we'll be working with MCUs in an embedded system, there will be some occasional discussions on the hardware side as well, primarily dealing with features of MCUs and development boards. These topics will be covered in enough detail that someone with minimal hardware knowledge should be able to follow without too much difficulty. You should be comfortable interacting with and handling development hardware, although there isn't any actual assembly required.

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: "func1() is responsible for reading the value of a sensor and storing it in
the sensorReadings array"

A block of code is set as follows:

void func1( int16_t calOffset)
{
int16_t tempValue;
tempValue = readSensor();
tempValue = tempValue + calOffset;
sensorReadings[0] = tempValue;
}

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

/* ADC Config */
hnucleo_Adc.Instance = NUCLEO_ADCx;
/* (ClockPrescaler must not exceed 36MHz) */
hnucleo_Adc.Init.ClockPrescaler = ADC_CLOCKPRESCALER_PCLK_DIV4;
hnucleo_Adc.Init.Resolution = ADC_RESOLUTION12b;
hnucleo_Adc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hnucleo_Adc.Init.ContinuousConvMode = DISABLE;
hnucleo_Adc.Init.DiscontinuousConvMode = DISABLE;

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: "Select System info from the Administration panel."

Warnings or important notes appear like this.
