Mikrocontroller wie der Arduino und Einplatinenrechner wie der Raspberry Pi haben sich zu beliebten Komponenten entwickelt. Dritter im Bunde ist der ESP32 der Firma Espressif. Mikrocontroller dieser Baureihe zeichnen sich durch eine Vielzahl implementierter Funktionen aus, die bei einem Arduino konventioneller Prägung mit einem Atmel-AVR-Mikrocontroller erst mit weiterer Hardware möglich sind. Prominentes Beispiel sind hier die WiFi- und Bluetooth-Funktionalitäten. Gegenüber einem Raspberry Pi zeichnen sie sich durch einen deutlich geringeren Preis aus.
Allgemeine Informationen für die Realisierung eines Roboterauto-Projekts mit dem ESP32 sind leicht zu finden. Dabei handelt es sich aber oft nur um Ausführungen zu einem Teilaspekt, ohne inhaltliche oder funktionale Abstimmung. So ist nicht nur die Beschaffung der benötigten Informationen mühselig und zeitaufwändig, sie kann auch außerordentlich fehlerträchtig sein.
Ansatzpunkt dieses Buches ist, diese Lücke zu schließen. Es geht auf verschiedene Möglichkeiten eines Chassis ein, vermittelt nötige Kenntnisse und führt schrittweise von einer einfachen Motorsteuerung zu einem komplexen sensor- und sprachgesteuerten Roboterauto. Hacks rund um GPS und eine PlayStation 3 runden die Sache ab.
Inhalt
Bei der Reihenfolge der Kapitel wurde versucht – beginnend bei der Darstellung von grundlegenden Informationen – über die Lösung einfacher Aufgaben zu etwas anspruchsvolleren Techniken zu führen.

Developing CoAP applications for Thread networks with Zephyr
This book will guide you through the operation of Thread, the setup of a Thread network, and the creation of your own Zephyr-based OpenThread applications to use it. You’ll acquire knowledge on:
The capture of network packets on Thread networks using Wireshark and the nRF Sniffer for 802.15.4.
Network simulation with the OpenThread Network Simulator.
Connecting a Thread network to a non-Thread network using a Thread Border Router.
The basics of Thread networking, including device roles and types, as well as the diverse types of unicast and multicast IPv6 addresses used in a Thread network.
The mechanisms behind network discovery, DNS queries, NAT64, and multicast addresses.
The process of joining a Thread network using network commissioning.
CoAP servers and clients and their OpenThread API.
Service registration and discovery.
Securing CoAP messages with DTLS, using a pre-shared key or X.509 certificates.
Investigating and optimizing a Thread device’s power consumption.
Once you‘ve set up a Thread network with some devices and tried connecting and disconnecting them, you’ll have gained a good insight into the functionality of a Thread network, including its self-healing capabilities. After you’ve experimented with all code examples in this book, you’ll also have gained useful programming experience using the OpenThread API and CoAP.

ARM Cortex-M Embedded Design from 0 to 1
Hobbyists can mash together amazing functional systems using platforms like Arduino or Raspberry Pi, but it is imperative that engineers and product designers understand the foundational knowledge of embedded design. There are very few resources available that describe the thinking, strategies, and processes to take an idea through hardware design and low-level driver development, and successfully build a complete embedded system. Many engineers end up learning the hard way, or never really learn at all.
ARM processors are essentially ubiquitous in embedded systems. Design engineers building novel devices must understand the fundamentals of these systems and be able to break down large, complicated ideas into manageable pieces. Successful product development means traversing a huge amount of documentation to understand how to accomplish what you need, then put everything together to create a robust system that will reliably operate and be maintainable for years to come.
This book is a case study in embedded design including discussion of the hardware, processor initialization, low‑level driver development, and application interface design for a product. Though we describe this through a specific application of a Cortex-M3 development board, our mission is to help the reader build foundational skills critical to being an excellent product developer. The completed development board is available to maximize the impact of this book, and the working platform that you create can then be used as a base for further development and learning.
The Embedded in Embedded program is about teaching fundamental skill sets to help engineers build a solid foundation of knowledge that can be applied in any design environment. With nearly 20 years of experience in the industry, the author communicates the critical skill development that is demanded by companies and essential to successful design. This book is as much about building a great design process, critical thinking, and even social considerations important to developers as it is about technical hardware and firmware design.
