  • Raspberry Pi Debug Probe - Elektor

    Raspberry Pi Foundation Raspberry Pi Debug Probe

    De Raspberry Pi Debug Probe is een alles-in-één USB-naar-debug-kit die alle benodigde hardware en kabels biedt voor eenvoudig, soldeerloos, plug-and-play debuggen. Het beschikt over zowel een seriële debug-interface voor de processor (standaard de ARM Serial Wire Debug-interface, maar andere interfaces kunnen worden ondersteund) en een industriestandaard UART-interface. Beide interfaces gebruiken de Raspberry Pi 3-pins debug-connector. Het is ontworpen om het debuggen en programmeren van Raspberry Pi Pico en RP2040 gemakkelijk te maken met een reeks hostplatforms, waaronder Windows, Mac en typische Linux-computers. Hoewel de Debug Probe ontworpen is voor gebruik met Raspberry Pi-producten, biedt hij standaard UART- en CMSIS-DAP-interfaces via USB, zodat hij ook met andere processors kan worden gebruikt, of zelfs gewoon als USB-naar-UART-kabel. Het werkt met OpenOCD en andere tools die CMSIS-DAP ondersteunen. De Debug Probe is gebaseerd op Raspberry Pi Pico-hardware en draait op de open source Raspberry Pi Picoprobe-software. De firmware wordt op dezelfde manier bijgewerkt als de Raspberry Pi Pico-firmware, dus het is gemakkelijk om het apparaat up-to-date te houden met de nieuwste firmware of om aangepaste firmware te gebruiken.

  • Programming with Node - RED (E - book) - Elektor

    Elektor Digital Programming with Node-RED (E-book)

    Design IoT Projects with Raspberry Pi, Arduino and ESP32 The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption. Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code. The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.

  • Electronic Security and Espionage - Elektor

    Elektor Publishing Electronic Security and Espionage

    A Handbook on DIY Nowadays, security problems are rarely properly solved or correctly addressed. Electronic security is only part of the chain in making a system secure. Electronic security is usually addressed as network or software security, neglecting other aspects, but the chain is only as strong as its weakest link. This book is about electronic hardware security, with an emphasis on problems that you can solve on a shoestring DIY budget. It deals mostly with secure communications, cryptosystems, and espionage. You will quickly appreciate that you can’t simply buy a trustworthy and reliable cryptosystem off the shelf. You will then realise that this applies equally to individuals, corporations, and governments. If you want to increase your electronic security awareness in a world already overcrowded with networks of microphones and cameras, this is a book for you. Furthermore, if you want to do something DIY by designing and expanding upon simple electronic systems, please continue reading. Some of the devices described are already published as projects in the Elektor magazine. Some are still ideas yet to be worked out. Complexity is the main enemy of security, so we'll try to keep to simple systems. Every chapter will analyse real-life espionage events or at least several hypothetical scenarios that will hopefully spark your imagination. The final goal is to build a security-conscious mindset (or “to get into a head of a spy”) which is necessary to recognise possible threats beforehand, to design a truly secure system. Don’t bother reading if: you think you and your secrets are 100% safe and secure you think somebody else can effectively handle your security you think conspiracy theories only exist in theory – Telefunken’s masterpiece the “FS-5000 Harpoon” was built on one!

    Elektor Digital Practical Audio DSP Projects with the ESP32 (E-book)

    Easy and Affordable Digital Signal ProcessingThe aim of this book is to teach the basic principles of Digital Signal Processing (DSP) and to introduce it from a practical point of view using the bare minimum of mathematics. Only the basic level of discrete-time systems theory is given, sufficient to implement DSP applications in real time. The practical implementations are described in real time using the highly popular ESP32 DevKitC microcontroller development board. With the low cost and extremely popular ESP32 microcontroller, you should be able to design elementary DSP projects with sampling frequencies within the audio range. All programming is done using the popular Arduino IDE in conjunction with the C language compiler.After laying a solid foundation of DSP theory and pertinent discussions on the main DSP software tools on the market, the book presents the following audio-based sound and DSP projects: Using an I²S-based digital microphone to capture audio sound Using an I²S-based class-D audio amplifier and speaker Playing MP3 music stored on an SD card through an I²S-based amplifier and speaker Playing MP3 music files stored in ESP32 flash memory through an I²S-based amplifier and speaker Mono and stereo Internet radio with I²S-based amplifiers and speakers Text-to-speech output with an I²S-based amplifier and speaker Using the volume control in I²S-based amplifier and speaker systems A speaking event counter with an I²S-based amplifier and speaker An adjustable sinewave generator with I²S-based amplifier and speaker Using the Pmod I²S2 24-bit fast ADC/DAC module Digital low-pass and band-pass real-time FIR filter design with external and internal A/D and D/A conversion Digital low-pass and band-pass real-time IIR filter design with external and internal A/D and D/A conversion Fast Fourier Transforms (FFT)
