The affordable STM32 Nucleo boards enable anyone to try out new ideas and instantly build prototypes with any STM32 MCU. Sharing identical connectors, the STM32 Nucleo boards can be effortlessly extended by a considerable number of functional application hardware add-ons (Nucleo-64 include Arduino Uno rev3 & ST morpho compatible connectors). The STM32 Nucleo boards integrate an ST-Link debugger/programmer, so there is no requirement for a separate probe. The STM Nucleo boards come with a complete STM32 software HAL library in combination with various software examples, and they work seamlessly with a wide range of development environments including IAR EWARM, Keil MDK-ARM, mbed and GCC/LLVM-based IDEs. STM32 Nucleo users have unrestricted access to the mbed online resources (compiler, C/C++ SDK, and developer community) at www.mbed.org, allowing to create a complete application within only a few minutes.

Programming with STM32 Nucleo Boards

The STM32 Nucleo family of processors are manufactured by STMicroelectronics. These are low-cost ARM microcontroller development boards. This book is about developing projects using the popular Nucleo development board. In the early chapters of the book, the architecture of the Nucleo family is briefly described. Software development tools that can be used with the Nucleo boards such as the Mbed, Keil MDK, TrueSTUDIO, and the System Workbench are described briefly in later Chapters.

The book covers many projects using most features of the STM32 Nucleo development boards, where the full software listings for Mbed and System Workbench are given for every project. The projects range from simple flashing LEDs to more complex projects using modules and devices such as GPIO, ADC, DAC, I²C, LCD, analog inputs, and others. Also, several projects are given using the Nucleo Expansion Boards, including popular expansion boards such as a solid-state relay, MEMS and environmental sensors, DC motor driver, Wi-Fi, and stepper motor driver.

These Expansion Boards plug on top of the Nucleo development boards and simplify the task of project development considerably.
