Cool Projects for Test, Measurement, and Control The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi. These problems can be elegantly solved with the Pico. As a front-end, it can easily handle a wide range of measurement tasks. In addition, the Pico is much cheaper than a classic Raspberry Pi 4 or 5. If a faulty circuit leads to the destruction of the Pico, this is relatively easy to handle. This makes the combination of a classic Raspberry Pi 4 or 5 and the Pico an ideal pair. The book introduces the broad and highly topical field of modern controller technology using the combined force of a Raspberry Pi 4 or 5 and a Raspberry Pi Pico. In addition to a detailed introduction to the operation and functionality of the controller boards themselves, the book also focuses on data acquisition and processing with digital processors. Especially the combination of both systems offers a wide range of interesting possibilities. Some practical projects from the contents: USB between Raspberry Pi 4 or 5 and Pico I²C Communication and Pico as an I²C device Voltmeter and Computer Thermometer Pico W as a Web Server and WLAN Scanner Frequency Meters and Generators OLED Displays on Raspberry Pi 4 or 5 and Pico Energy Saving Monitor Which Astronauts are in Orbit?

Projects Using Arduino IDE and the LVGL Graphics Library The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays. The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches. All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.

Zeitsteuerung, Scheduler, PIO und Zustandsmaschinen Multitasking ist der Schlüssel zu leistungsfähigen Embedded-Systemen, und zugleich eine der größten Herausforderungen in der Mikrocontroller-Programmierung. Dieses Buch zeigt Ihnen Schritt für Schritt, wie Sie von einem einfachen Ein-Task-Programm zu einem strukturierten, reaktionsfähigen und skalierbaren System gelangen. Dabei steht nicht nur das Wie, sondern vor allem das Warum im Mittelpunkt. Sie lernen: warum scheinbare Parallelität entsteht weshalb blockierende Programme instabil werden wie Aufgaben effizient und kontrolliert parallel ablaufen Ausgehend vom klassischen Superloop vermittelt das Buch moderne Multitasking-Strategien – von nicht-blockierender Programmierung und Tick-Systemen bis zu Task-Schedulern, Zustandsmaschinen und ereignisgesteuerten Konzepten. Der Fokus liegt auf der Praxis: Sensoren, Displays, Kommunikation und reale Anwendungen werden Schritt für Schritt integriert und mit verständlich kommentierten Beispielprogrammen erklärt. Fortgeschrittene Themen umfassen: Multicore-Programmierung mit dem Raspberry Pi Pico asynchrones Programmieren mit uasyncio RTOS-Grundlagen mit FreeRTOS die Kombination aus Multicore und RTOS Dabei werden auch die Grenzen dieser Techniken, insbesondere unter MicroPython, klar aufgezeigt. Das Buch richtet sich an ambitionierte Einsteiger und fortgeschrittene Entwickler, die Embedded-Systeme fundiert verstehen und robuste, wartbare Multitasking-Anwendungen entwickeln möchten.
