Programming and Projects for the Minima and WiFi Based on the low-cost 8-bit ATmega328P processor, the Arduino Uno R3 board is likely to score as the most popular Arduino family member, and this workhorse has been with us for many years. Eleven years later, the long-overdue successor, the Arduino Uno R4, was released. It is built around a 48 MHz, 32-bit Arm Cortex-M4 microcontroller and provides significantly expanded SRAM and Flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The Uno R4 board also supports the CAN Bus with an interface. Two versions of the board are available: Uno R4 Minima, and Uno R4 WiFi. This book is about using these new boards to develop many different and interesting projects with just a handful of parts and external modules. All projects described in the book have been fully tested on the Uno R4 Minima or the Uno R4 WiFi board, as appropriate. The project topics include the reading, control, and driving of many components and modules in the kit as well as on the relevant Uno R4 board, including LEDs 7-segment displays (using timer interrupts) LCDs Sensors RFID Reader 4x4 Keypad Real-time clock (RTC) Joystick 8×8 LED matrix Motors DAC (Digital-to-analog converter) LED matrix WiFi connectivity Serial UART CAN bus Infrared controller and receiver Simulators … all in creative and educational ways with the project operation and associated software explained in great detail.

It is becoming important for microcontroller users to quickly learn and adapt to new technologies and architecture used in high performance 32-bit microcontrollers. Many manufacturers now offer 32-bit microcontrollers as general purpose processors in embedded applications. ARM provide 32 and 64-bit processors mainly for embedded applications. These days, the majority of mobile devices including mobile phones, tablets, and GPS receivers are based on ARM technology. The low cost, low power consumption, and high performance of ARM processors makes them ideal for use in complex communication and mixed signal applications. This book makes use of the ARM Cortex-M family of processors in easy-to-follow, practical projects. It gives a detailed introduction to the architecture of the Cortex-M family. Examples of popular hardware and software development kits are described. The architecture of the highly popular ARM Cortex-M processor STM32F107VCT6 is described at a high level, taking into consideration its clock mechanisms, general input/output ports, interrupt sources, ADC and DAC converters, timer facilities, and more. The information provided here should act as a basis for most readers to start using and programming the STM32F107VCT6 microcontroller together with a development kit. Furthermore, the use of the mikroC Pro for ARM integrated development environment (IDE) has been described in detail. This IDE includes everything required to create a project; namely an editor, compiler, simulator, debugger, and device programmer. Although the book is based on the STM32F107VCT6 microcontroller, readers should not find it difficult to follow the projects using other ARM processor family members.

Le Raspberry Pi Pico est un microcontrôleur de haute performance conçu spécialement pour l'informatique physique. N'ayant pas de système d'exploitation, les microcontrôleurs diffèrent des ordinateurs monocartes, comme le Raspberry Pi 4. Le Raspberry Pi Pico peut être programmé pour exécuter efficacement une seule tâche dans des applications de contrôle et de surveillance en temps réel nécessitant de la rapidité. Le 'Pico', comme on l'appelle, est basé sur le microcontrôleur ARM Cortex-M0+ RP2040 à double cœur, rapide, efficace et peu coûteux, fonctionnant jusqu'à 133 MHz et disposant de 264 Ko de SRAM et de 2 Mo de mémoire Flash.
