The newcomer to Microchip’s PIC microcontrollers invariably gets an LED to flash as their first attempt to master this technology. You can use just a simple LED indicator in order to show that your initial attempt is working, which will give you confidence to move forward. This is how the book begins — simple programs to flash LEDs, and eventually by stages to use other display indicators such as the 7-segment display, alphanumeric liquid crystal displays and eventually a colour graphic LCD. As the reader progresses through the book, bigger and upgraded PIC chips are introduced, with full circuit diagrams and source code, both in assembler and C. In addition, a small tutorial is included using the MPLAB programming environment, together with the EAGLE schematic and PCB design package to enable readers to create their own designs using the book’s many case studies as working examples to work from.

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.

De werking van veruit de meeste moderne elektronische apparaten is niet slechts op één enkel principe gebaseerd. Vaak staat een of andere computer (doorgaans een microcontroller) centraal. Uit deze fundamentele opzet – een computer die is ingebed in een bepaalde toepassingsschakeling – is de algemene benaming Embedded Systems voortgekomen. De meeste van deze systemen moeten vanuit het niets worden ontwikkeld, en daarbij komt het op elk detail aan. Vindingrijkheid en veelzijdigheid zijn dan een vereiste. De problemen die opgelost moeten worden, vormen niet zelden een ware uitdaging en betreffen niet alleen de analoge en digitale elektronica maar ook de systeemarchitectuur, programmering en programma-organisatie. De delen van deze reeks zijn geschreven voor iedereen – leerling, student of beginnend elektronicus – die zich terdege wil bekwamen in de professionele hardware- en systeemontwikkeling. En ze richten zich tot de allround-elektronicus die geen tijd heeft om specialist op een van de vele deelgebieden te worden maar die weet dat hij met standaard huis-, tuin- en keukenoplossingen niet ver komt. Ze bieden wat studenten en professionele elektronici nodig hebben: een opfrissing en verdieping van de basiskennis, een bron van inspiratie en een schat aan details en spitsvondigheden. Dit deel behandelt de passieve componenten: vaste weerstanden instelbare weerstanden NTC- en PTC-weerstanden spanningsafhankelijke weerstanden condensatoren spoelen transformatoren contactelementen

An Introduction to RISC-V RISC-V is an Instruction Set Architecture (ISA) that is both free and open. This means that the RISC-V ISA itself does not require a licensing fee, although individual implementations may do so. The RISC-V ISA is curated by a non-profit foundation with no commercial interest in products or services that use it, and it is possible for anyone to submit contributions to the RISC-V specifications. The RISC-V ISA is suitable for applications ranging from embedded microcontrollers to supercomputers. This book will first describe the 32-bit RISC-V ISA, including both the base instruction set as well as the majority of the currently-defined extensions. The book will then describe, in detail, an open-source implementation of the ISA that is intended for embedded control applications. This implementation includes the base instruction set as well as a number of standard extensions. After the description of the CPU design is complete the design is expanded to include memory and some simple I/O. The resulting microcontroller will then be implemented in an affordable FPGA development board (available from Elektor) along with a simple software application so that the reader can investigate the finished design.

Projects with Thonny-IDE, uPyCraft-IDE, and ESP32 The 'Python' programming language has enjoyed an enormous upswing in recent years. Not least, various single-board systems such as the Raspberry Pi have contributed to its popularity. But Python has also found widespread use in other fields, such as artificial intelligence (AI) or machine learning (ML). It is obvious, therefore, to use Python or the 'MicroPython' variant for use in SoCs (Systems on Chip) as well. Powerful controllers such as the ESP32 from Espressif Systems offer excellent performance as well as Wi-Fi and Bluetooth functionality at an affordable price. With these features, the Maker scene has been taken by storm. Compared to other controllers, the ESP32 has a significantly larger flash and SRAM memory, as well as a much higher CPU speed. Due to these characteristics, the chip is not only suitable for classic C applications, but also for programming with MicroPython. This book introduces the application of modern one-chip systems. In addition to the technical background, the focus is on MicroPython itself. After the introduction to the language, the programming skills learned are immediately put into practice. The individual projects are suitable for use in the laboratory as well as for everyday applications. So, in addition to the actual learning effect, the focus is also on the joy of building complete and useful devices. By using laboratory breadboards, circuits of all kinds can be realized with little effort, turning the testing and debugging of the 100% homebrew projects into an instructive pleasure. The various applications, such as weather stations, digital voltmeters, ultrasound range finders, RFID card readers or function generators, make the projects presented ideally suited for practical courses or subject and study work in the natural sciences, or in science and technology classes.
