PIC und AVR verstehen
In diesem Buch werden wir uns ausschließlich mit 8-Bit-Mikrocontrollern beschäftigen, und zwar mit Mikrocontrollern der 8-Bit-PIC- und der 8-Bit-AVR-Mikrocontroller-Linien. Bei der PIC-Familie handelt es sich dabei um PIC10, PIC12, PIC16 und PIC18; bei der AVR-Familie um ATtiny, ATmega und ATxmega. Die vorgestellten 8-Bit-Chips sind für sehr viele Anwendungen vollkommen ausreichend und preislich auch attraktiv.
Durch die Lektüre des Buches erhalten Sie ein fundiertes Wissen über die genannten 8-Bit-Mikrocontroller, über ihre Architektur, ihre Pinbelegungen und über ihre Programmierung.
Weil wir uns in diesem Buch mit den Grundlagen der Architektur der PICs und AVRs vertraut machen möchten, werden wir auch für alle PIC- und AVR-Anwendungen Assembler einsetzen, denn die Assembler-Sprache erlaubt es, die Technik im Detail kennenzulernen. Wenn man wirklich wissen möchte, was sich im Mikrocontroller abspielt, greift man zu Assembler. Damit hat man die beste Gelegenheit, sehr nah an den Kern zu kommen. Und wenn man schon einen Mikrocontroller-Typ kennengelernt und verstanden hat, ist es bei dem nächsten deutlich einfacher, auch wenn er von einem anderen Hersteller kommt. Bei anderen Programmiersprachen bleibt die Technik immer ziemlich tief versteckt.
Die Assembler-Beispiele sind so einfach gestaltet, dass sie jeder mit den im Buch aufgezeigten Programmiertechniken erstellen kann. Weil es sich um einfache Beispiele handelt, werden wir sie alle auf einer universellen Lochrasterplatine realisieren. Manche sind auch auf einem Experimentier-Breadboard umsetzbar.
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.
This multi-axis robot perfectly balances power and size.

Programming and Projects for the Minima and WiFi
Based on the low-cost 8-bit ATmega328P processor, the Arduino Uno R3 board is likely to score as the most popular Arduino family member, and this workhorse has been with us for many years. Eleven years later, the long-overdue successor, the Arduino Uno R4, was released. It is built around a 48 MHz, 32-bit Arm Cortex-M4 microcontroller and provides significantly expanded SRAM and Flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The Uno R4 board also supports the CAN Bus with an interface.
Two versions of the board are available: Uno R4 Minima, and Uno R4 WiFi. This book is about using these new boards to develop many different and interesting projects with just a handful of parts and external modules. All projects described in the book have been fully tested on the Uno R4 Minima or the Uno R4 WiFi board, as appropriate.
The project topics include the reading, control, and driving of many components and modules in the kit as well as on the relevant Uno R4 board, including
LEDs
7-segment displays (using timer interrupts)
LCDs
Sensors
RFID Reader
4x4 Keypad
Real-time clock (RTC)
Joystick
8×8 LED matrix
Motors
DAC (Digital-to-analog converter)
