Learn to program displays and GUIs with Python This book is about Raspberry Pi 4 display projects. The book starts by explaining how to install the latest Raspbian operating system on an SD card, and how to configure and use the GPIO ports. The core of the book explains the following topics in simple terms with fully tested and working example projects: Simple LED projects Bar graph LED projects Matrix LED projects Bitmap LED projects LED strips LCDs OLED displays E-paper displays TFT displays 7-inch touch screen GUI Programming with Tkinder One unique feature of this book is that it covers almost all types of display that readers will need to use in their Raspberry Pi based projects. The operation of each project is fully given, including block diagrams, circuit diagrams, and commented full program listings. It is therefore an easy task to convert the given projects to run on other popular platforms, such as Arduino or PIC microcontrollers. Python program listings of all Raspberry Pi projects developed in this book are available for download at Elektor.com. Readers can use these programs in their projects. Alternatively, they can modify the programs to suit their applications.

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.

Dieses Buch bietet Ihnen einen praxisnahen Einstieg in die klassischen und modernen Methoden der Regelung, darunter PID-Regler, Fuzzy-Logik und Sliding-Mode-Regler. Im ersten Teil lernen Sie die Grundlagen der beliebten Arduino-Controller, wie den Arduino Uno und den ESP32, sowie die Integration von Sensoren für Temperatur- und pH-Messung (NTC, PT100, PT1000, pH-Sensor). Sie erfahren, wie diese Sensoren in verschiedenen Projekten eingesetzt werden und wie Sie Daten auf einem Nextion TFT-Display visualisieren. Weiter geht es mit der Einführung in Stellglieder wie MOSFET-Schalter, H-Brücken und Solid-State-Relais, die zur Steuerung von Motoren und Aktoren verwendet werden. Sie lernen, Regelstrecken zu analysieren und zu modellieren, einschließlich PT1- und PT2-Regelungen. Der Schwerpunkt des Buches liegt auf der Implementierung von Fuzzy- und PID-Reglern zur Regelung von Temperatur und DC-Motoren. Dabei werden sowohl der Arduino Uno als auch der ESP32 eingesetzt. Zudem wird der Sliding-Mode-Regler vorgestellt. Im vorletzten Kapitel erkunden Sie die Grundlagen neuronaler Netze und lernen, wie maschinelles Lernen auf einem Arduino eingesetzt werden kann. Im letzten Kapitel gibt es noch ein praktisches Beispiel für einen Fuzzy-Regler zur Stromeinspeisung ins Hausnetz. Dieses Buch ist die perfekte Wahl für Ingenieure, Studierende und Elektroniker, die ihre Projekte mit innovativen Regelungstechniken erweitern möchten.

Practical Multitasking Fundamentals Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation? Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs. Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher. Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project. What you will learn: How preemptive scheduling works within FreeRTOS The Arduino startup “loopTask” Message queues FreeRTOS timers and the IDLE task The semaphore, mutex, and their differences The mailbox and its application Real-time task priorities and its effect Interrupt interaction and use with FreeRTOS Queue sets Notifying tasks with events Event groups Critical sections Task local storage The gatekeeper task
