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.

TapNLink-Module bieten drahtlose Schnittstellen zur Verknüpfung elektronischer Systeme mit mobilen Geräten und der Cloud. TapNLink stellt eine direkte Verbindung zum Mikrocontroller des Zielsystems her. Es integriert sich in das Zielsystem und wird von diesem mit Strom versorgt. Alle TapNLink-Produkte lassen sich einfach konfigurieren, um den Zugriff verschiedener Benutzertypen auf Daten im Zielsystem zu steuern. TapNLink ermöglicht die schnelle Erstellung von Human Machine Interfaces (HMI), die auf Android-, iOS- und Windows-Mobilgeräten laufen. HMI-Apps lassen sich leicht an verschiedene Benutzer anpassen und können bereitgestellt und aktualisiert werden, um mit den sich ändernden Systemanforderungen und Benutzerbedürfnissen Schritt zu halten. TapNLink-WLAN-Module können auch so konfiguriert werden, dass sie das Zielsystem dauerhaft mit einem drahtlosen Netzwerk und der Cloud verbinden. Dies ermöglicht eine permanente Protokollierung von Zielsystemdaten und Alarmen.

50+ Android Apps with Raspberry Pi, ESP32 and Arduino This book is about developing apps for Android compatible mobile devices using the MIT App Inventor online development environment. MIT App Inventor projects can be in either standalone mode or use an external processor. In standalone mode, the developed application runs only on the mobile device (e.g. Android). In external processor-based applications, the mobile device communicates with an external microcontroller-based processor, such as Raspberry Pi, Arduino, ESP8266, ESP32, etc. In this book, many tested and fully working projects are given both in standalone mode and using an external processor. Full design steps, block programs, circuit diagrams, QR codes and full program listings are given for all projects. The projects developed in this book include: Using the text-to-speech component Intonating a received SMS message Sending SMS messages Making telephone calls using a contacts list Using the GPS and Pin-pointing our location on a map Speech recognition and speech translation to another language Controlling multiple relays by speech commands Projects for the Raspberry Pi, ESP32 and Arduino using Bluetooth and Wi-Fi MIT APP Inventor and Node-RED projects for the Raspberry Pi The book is unique in that it is currently the only book that teaches how to develop projects using Wi-Fi and Node-RED with MIT App Inventor. The book is aimed at students, hobbyists, and anyone interested in developing apps for mobile devices. All projects presented in this book have been developed using the MIT App Inventor visual programming language. There is no need to write any text-based programs. All projects are compatible with Android-based mobile devices. Full program listings for all projects as well as detailed program descriptions are given in the book. Users should be able to use the projects as they are presented, modifying them to suit their own needs.

STmicroelectronics’ wireless IoT & wearable sensor development kit ‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box. The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box. This book is an introduction to the SensorTile.box and includes the following: Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box. Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone. An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps. The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time. Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.
