Mikrocontroller haben sich in den letzten Jahren in praktisch allen Bereichen der modernen Technik etabliert. In zunehmendem Maße dringen sie auch in die Gebiete der Künstlichen Intelligenz und der Robotertechnik vor. Das vorliegende Buch gibt eine umfassende Einführung in die Welt der Controller-Technik mit all ihren Facetten, von der einfachen Steuerung über die Sensor-Technik bis hin zur Datenübertragung in das Internet.
Als Basis dafür dient das von Elektor entwickelte AVR-Playground-Board. Das Board kann mit Controllern der ATmega-Familie bestückt werden und ist mit dem bekannten Arduino-System kompatibel, so dass auch die verschiedenen Arduino-Hardware-Erweiterungen verwendet werden können.
Für die Programmierung kommt die Sprache „C“ zum Einsatz. Auch hier wird im Buch auf das Arduino-System zurückgegriffen. Die frei verfügbare Arduino-Entwicklungsumgebung erlaubt den leichten Einstieg, ohne dass später Einschränkungen in Kauf genommen werden müssen. Die Hardware-nahe Programmierung steht dabei besonders im Fokus. Nach der Erläuterung von grundlegenden Anwendungen wird auf die anspruchsvolleren Themen wie Interrupts, Timer und Counter, Pulsweitenmodulation und Analog-Digital-Wandlung eingegangen.
Praktische Anwendungen können sowohl mit einem Arduino als auch mit dem AVR-Playground-Board durchgeführt werden. Da das AVR-Playground-Board bereits über eine Vielzahl von Peripherie-Einheiten verfügt, sind nur noch wenige externe Bauteile erforderlich. Das Board kann im Elektor-Shop hier bezogen werden.
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.
The 8x10" iFixit Magnetic Project Mat catches and securely holds screws as you pull them out of a device. Now you can stop worrying about keeping track of all the loose screws and focus on your repair. Screws and small parts will remain right where you left them. For laptops with hundreds of screws, use the whole mat as a screw guide and keep careful location notes.
Included is a pen — made by Staedtler, producer of top-of-the-line pens and pencils for artists and architects — that was specially designed for the Project Mat. The Lumocolor Correctable pen resists smears and won't wipe away with a casual brush of your hand. When your repair is complete, use the eraser tip or a dry cloth to wipe the ink away clean.
Kenmerken
Organize all your small parts while you work on a device.
The dry-erase surface lets you keep notes and location sketches.
Reduces reassembly time by up to 40% while preventing errors.
Raspberry Pi 5 provides two four-lane MIPI connectors, each of which can support either a camera or a display. These connectors use the same 22-way, 0.5 mm-pitch “mini” FPC format as the Compute Module Development Kit, and require adapter cables to connect to the 15-way, 1 mm-pitch “standard” format connectors on current Raspbery Pi camera and display products.These mini-to-standard adapter cables for cameras and displays (note that a camera cable should not be used with a display, and vice versa) are available in 200 mm, 300 mm and 500 mm lengths.
The Peak Atlas ZEN50 is ideal for testing Zener diodes (including avalanche diodes), transient suppressors, LEDs and LED strings. It generates constant current pulses (selectable from 2 mA, 5 mA, 10 mA and 15 mA) at voltages from 0V to 50V. So even high voltage Zeners or high voltage LED strings can be tested.
Test currents are supplied in narrow pulses to ensure that the component under test remains at a constant temperature.
The voltage of the part is displayed on the screen together with the test current and also a measure of the component's slope resistance (also known as dynamic impedance).
