Recently, the development of a tiny chip called the ESP8266 has made it possible to interface any type of microcontroller to a Wi-Fi AP. The ESP8266 is a low-cost tiny Wi-Fi chip having fully built-in TCP/IP stack and a 32-bit microcontroller unit. This chip, produced by Shanghai based Chinese manufacturer Espressif System, is IEEE 802.11 b/g/n Wi-Fi compatible with on-chip program and data memory, and general purpose input-output ports. Several manufacturers have incorporated the ESP8266 chip in their hardware products (e.g. ESP-xx, NodeMCU etc) and offer these products as a means of connecting a microcontroller system such as the Android, PIC microcontroller or others to a Wi-Fi. The ESP8266 is a low-power chip and costs only a few Dollars. ESP8266 and MicroPython – Coding Cool Stuff is an introduction to the ESP8266 chip and describes the features of this chip and shows how various firmware and programming languages such as the MicroPython can be uploaded to the chip. The main aim of the book is to teach the readers how to use the MicroPython programming language on ESP8266 based hardware, especially on the NodeMCU. Several interesting and useful projects are given in the e-book (pdf) to show how to use the MicroPython in NodeMCU type ESP8266 hardware: Project “What shall I wear today?”: You will be developing a weather information system using a NodeMCU development board together with a Text-to-Speech processor module. Project “The Temperature and Humidity on the Cloud”: You will be developing a system that will get the ambient temperature and humidity using a sensor and then store this data on the cloud so that it can be accessed from anywhere. Project “Remote Web Based Control”: You will be developing a system that will remotely control two LEDs connected to a NodeMCU development board using an HTTP Web Server application.

It is becoming important for microcontroller users to quickly learn and adapt to new technologies and architecture used in high performance 32-bit microcontrollers. Many manufacturers now offer 32-bit microcontrollers as general purpose processors in embedded applications. ARM provide 32 and 64-bit processors mainly for embedded applications. These days, the majority of mobile devices including mobile phones, tablets, and GPS receivers are based on ARM technology. The low cost, low power consumption, and high performance of ARM processors makes them ideal for use in complex communication and mixed signal applications. This book makes use of the ARM Cortex-M family of processors in easy-to-follow, practical projects. It gives a detailed introduction to the architecture of the Cortex-M family. Examples of popular hardware and software development kits are described. The architecture of the highly popular ARM Cortex-M processor STM32F107VCT6 is described at a high level, taking into consideration its clock mechanisms, general input/output ports, interrupt sources, ADC and DAC converters, timer facilities, and more. The information provided here should act as a basis for most readers to start using and programming the STM32F107VCT6 microcontroller together with a development kit. Furthermore, the use of the mikroC Pro for ARM integrated development environment (IDE) has been described in detail. This IDE includes everything required to create a project; namely an editor, compiler, simulator, debugger, and device programmer. Although the book is based on the STM32F107VCT6 microcontroller, readers should not find it difficult to follow the projects using other ARM processor family members.

Ein Blick in die einschlägigen Internetforen zeigt, dass das Programmieren immer noch in der Gruppe der beliebten Hobbys rangiert. Wo dem Hobbyprogrammierer früher eine Reihe bekannter und populärer Programmiersprachen zur Verfügung standen, ist es heute relativ übersichtlich geworden: Außer C++, Java und Visual Basic gibt es wenig bekannte und beliebte Programmiersprachen. Was fehlt, ist eine Programmiersprache, die für Laien fast so einfach zu handhaben ist wie die alten BASIC-Versionen, deren Leistung und Features dennoch an die Möglichkeiten und die Power moderner Windows-Rechner angepasst sind. Diese Programmiersprache existiert und heißt Processing. Das vorliegende Buch führt den Leser in diese visuelle Programmiersprache ein. Das Buch richtet sich an Leser, die bereits allgemeine Erfahrungen im Umgang mit Programmiersprachen besitzen und wissen, worum es sich bei Strings, Arrays oder Schleifen handelt. Der Autor zeigt anhand vieler kurzer Programmbeispiele, wie einfach es ist, mit Processing auch leistungsfähige Software zu programmieren und sich dabei auf eine nur geringe Anzahl von Befehlen, Anweisungen und Funktionen zu beschränken. Die in diesem Buch vorgestellten Programme sind zum Teil Hardware-orientiert, wobei auch die Erfassung von Daten und die Steuerung von Hardware mittels des bekannten Mikrocontrollers Arduino einer Rolle spielt. Kurz und gut: Ein Buch für alle, die eine schnell und einfach zu programmierende Software mit elektronischer Hardware kombinieren und das Ganze über maßgeschneiderte Benutzeroberflächen steuern möchten.
