Elektor Digital RISC-V Assembly Language Programming using ESP32-C3 and QEMU (E-book)
With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available?The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book.The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have “aha!” moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you’ll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you’ve mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.

Elektor Digital PID-based Practical Digital Control with Raspberry Pi and Arduino Uno (E-book)
The Arduino Uno is an open-source microcontroller development system encompassing hardware, an Integrated Development Environment (IDE), and a vast number of libraries. It is supported by an enormous community of programmers, electronic engineers, enthusiasts, and academics. The libraries in particular really smooth Arduino programming and reduce programming time. What’s more, the libraries greatly facilitate testing your programs since most come fully tested and working. The Raspberry Pi 4 can be used in many applications such as audio and video media devices. It also works in industrial controllers, robotics, games, and in many domestic and commercial applications. The Raspberry Pi 4 also offers Wi-Fi and Bluetooth capability which makes it great for remote and Internet-based control and monitoring applications. This book is about using both the Raspberry Pi 4 and the Arduino Uno in PID-based automatic control applications. The book starts with basic theory of the control systems and feedback control. Working and tested projects are given for controlling real-life systems using PID controllers. The open-loop step time response, tuning the PID parameters, and the closed-loop time response of the developed systems are discussed together with the block diagrams, circuit diagrams, PID controller algorithms, and the full program listings for both the Raspberry Pi and the Arduino Uno. The projects given in the book aim to teach the theory and applications of PID controllers and can be modified easily as desired for other applications. The projects given for the Raspberry Pi 4 should work with all other models of Raspberry Pi family. The book covers the following topics: Open-loop and closed-loop control systems Analog and digital sensors Transfer functions and continuous-time systems First-order and second-order system time responses Discrete-time digital systems Continuous-time PID controllers Discrete-time PID controllers ON-OFF temperature control with Raspberry Pi and Arduino Uno PID-based temperature control with Raspberry Pi and Arduino Uno PID-based DC motor control with Raspberry Pi and Arduino Uno PID-based water level control with Raspberry Pi and Arduino Uno PID-based LED-LDR brightness control with Raspberry Pi and Arduino Uno

PeakTech PeakTech 2710 Digital RCD Tester
Residual current circuit breakers are used for personal protection and switch off a circuit when a fault current is detected, which flows through the protective earthing (PE). This RCD tester determines the tripping current and the tripping time of residual current circuit breakers which are used in every new building according to current building regulations. The various selectable test currents and characteristics of the FI allow flexible use of this instrument. FI testers allow a fault current to flow and determine at which fault current the FI reacts. Furthermore, the trip time is measured. These two parameters tripping current and tripping time are the safety-relevant characteristics of a residual-current-operated switch. 3-digit LCD display with backlight Normal (N) or Selective (S) -type RCD test Applicable measurement standards: IEC 61557-6, NF EN 61557-6, VDE 0413-6 Accessories: Carrying case, Test leads, Batteries and User manual Technical Specifications Nominal test current 10/30/100/500/1000mA Current selection 0.5x, 1x, 2x, 5x nominal current Trip time 10-2000 ms at 0.5 x 10-500 ms at 1x 10-150 ms at 2x 10-40 ms at 5x Ramp test 0.4 x to 1.4 times nominal rated current RCD Types Type-A, Type-AC Operation voltage 6 x 1,5 V AA (UM-3) batteries Dimensions (WxHxD) 92 x 200 x 50 mm Weight 700 g
