![]() ![]() For our examples, so also a Windows PC is required. files from STM32CubeMXĪs already said, we will use for our examples a NUCLEO-L053R8 board. Obviously, this is a very simple practical example, but peripherals, communication protocols and anything else can be configured in a similar way. The steps required to configure a core board are explained below. This can be easily done with a Nucleo board by configuring a GPIO (General Purpose Input Output) pin. In this case when the switch is closed the Led is ON, when the switch is open the Led is OFF. Now we must be able to turn off the led, to do it we need a switch to connect and disconnect the power supply as shown below. What resistance value must be considered to limit the current to 20 mA (see the formula below)? We must connect in series to LED a resistor. First, let's turn on the led, to do this we have to connect the LED to the power supply (on Nucleo we can find 3.3V and 5V).Turning a LED on and off is a basic and classical experiment when dealing with NUCLEO for the first time.Various basic electrical components such as Resistors (THT), Capacitors (THT), Buzzers, LEDs, etc.Jumper Cables Kit to connect the Nucleo board to breadboard or other components.Breadboard to hold and connect the simple electrical components.USB 2.0 Cable - A-Male to Mini-B Cord to connect PC to ST-LINK.STM32 Nucleo board (in our example we will use NUCLEO-L053R8, but you can use the one you prefer, as already said all Nucleo boards are pinout compatible).At this point, you can install it, if you'll find problems you can check the " UM2563 - STM32CubeIDE installation guide".In order to do it, you have to go on the ST site and after registered in it you can navigate to " " to download it. First of all, you have to install on your PC the STM32CubeIDE.We will dive into these steps with a simple example in the next paragraph. At any time, the user can go back and change initializations and configurations, without affecting the user code. At this point, the initialization code is generated. To start the project, you must first select the MCU and then initialize and configure the peripherals the user wants to use. The framework used is Eclipse®/CDT, as tool-chain for the development is used GCC toolchain and GDB for the debugging. STM32CubeIDE allows using a single platform to configure peripherals, to generate/compile/debug the code for STM32 microcontrollers and microprocessors. STM32CubeIDE is a development tool and supports multi operative system (SO), which is part of the STM32Cube software ecosystem. These Expansion Boards plug on top of the Nucleo development boards and simplify the task of project development considerably.We will use for our examples STM32CubeIDE released by ST and completely free. In addition, several projects are given using the Nucleo Expansion Boards, including popular expansion boards such as solid-state relay, MEMS and environmental sensors, DC motor driver, Wi-Fi, and stepper motor driver. The projects range from simple flashing LEDs to more complex projects using modules and devices such as GPIO, ADC, DAC, I☬, LCD, analog inputs and others. 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. 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. In the early chapters of the book, the architecture of the Nucleo family is briefly described. This book is about developing projects using the popular Nucleo development board. These are low-cost ARM microcontroller development boards. STM32 Nucleo family of processors are manufactured by STMicroelectronics. ![]()
