Die WiFi-Module der chinesischen Firma Espressif haben schon längst die Maker-Community erobert, bieten sie doch zu einem konkurrenzlosen Preis MCU- und WiFi-Funktionalität. Mit einfachen Mitteln lässt sich ein Arduino mit einem ESP-Modul um WiFi erweitern. Die globale Bastler-Gemeinde ersetzte schon bald die integrierte Firmware mit eigener Firmware, sodass Entwickler ESP-Boards wie Arduino-Boards programmieren können. Der neue ESP32 geht einen Schritt weiter und ist in jeder Beziehung leistungsfähiger als der ESP8266. Zudem besitzt er nun Bluetooth-Funktionalität. Der ESP32 verfügt über einen 240-MHz-Zweikern-Mikroprozessor mit einer Performanz von 600 DMIPS. Neben 520 KByte SRAM befinden sich 16 MByte Flashspeicher an Board. Zur Kommunikation mit der Außenwelt enthält das System-on-a-Chip die 802.11-b/g/n-WiFi-Komponente HT40 und Bluetooth-Funktionalität. Als Sensoren bietet der ESP32 einen Hall-Sensor, eine zehnfache, kapazitive Touch-Schnittstelle, einen analogen Verstärker für niedrige Signale und einen 32-kHz-Kristallquartz. Der Bestseller-Autor Erik Bartmann hat sich ausführlich mit dem ESP32 beschäftigt. Heraus gekommen ist dabei Das ESP32-Praxisbuch, in dem er die Leser Schritt für Schritt in die Arbeit mit diesem preiswerten WiFi-Mikrocontroller einführt.

Practical Applications and Project with Arduino, ESP32, and RP2040 Immerse yourself in the fascinating world of control engineering with Arduino and ESP32! This book offers you a practical introduction to classic and modern control methods, including PID controllers, fuzzy logic, and sliding-mode controllers. In the first part, you will learn the basics of the popular Arduino controllers, such as the Arduino Uno and the ESP32, as well as the integration of sensors for temperature and pH measurement (NTC, PT100, PT1000, and pH sensor). You will learn how to use these sensors in various projects and how to visualize data on a Nextion TFT display. The course continues with an introduction to actuators such as MOSFET switches, H-bridges, and solid-state relays, which are used to control motors and actuators. You will learn to analyze and model controlled systems, including PT1 and PT2 control. The book focuses on the implementation of fuzzy and PID controllers for controlling temperature and DC motors. Both the Arduino Uno and the ESP32 are used. The sliding-mode controller is also introduced. In the second-to-last chapter, you will explore the basics of neural networks and learn how machine learning can be used on an Arduino. In the last chapter, there is a practical example of a fuzzy controller for feeding electricity into the household grid. This book is the perfect choice for engineers, students, and electronics engineers who want to expand their projects with innovative control techniques.

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
