More fun and effortless ARM code inspection & debugging

Black Magic Probe – JTAG & SWD ARM debugger is a very small and lightweigh board designed for more efficient embedded programming. When you run into a problem with a program you are writing, the Black Magic Probe allows you to follow the execution step by step. Run your program in real-time and interrupt it at any step to inspect and modify CPU registers or variables or watch them as they change. You can also inspect the Function Call Stack and much more. You'll do the right things right in time! Instead of complex and expensive proprietary black-box tools, you’ll find openness, simplicity, and reliability. Forget about difficult to set up and maintain open source solutions.

The M5Stack takes a different approach to ESP32 prototyping as projects developed on it are finished products at the same time. This is possible because the board is built into a nice-looking enclosure including a graphical display, pushbuttons, microSD card slot, USB-C, and loudspeaker. But there is much more...

Messages can be encrypted to prevent their contents to be intercepted or altered. However, to read the message the intended receiver must be in the posession of the decryption key, which raises the question of how to send the key in a secure way to the destination? This project tries to solve this chicken-and-egg problem by adding tamper detection to the envelope.

Retrofitting speech recognition to existing objects is possible thanks to all sorts of kits that have started popping up the last few years. In this article we look at one of these: the Grove Speech Recognizer Kit for Arduino from Seeed.

To update the software of a vintage microcontroller system you can simply replace the whole system or try to modify it. Replacing often means throwing away parts that work perfectly fine, which some people find hard to accept. If the old hardware is based on the venerable 8051 microcontroller then here's a way to replace it by a modern AVR micro while keeping all the rest. Immediate access to the wonderful world of Arduino is thrown in for free.

Microchip Technology Inc. announces a new 2D Touch Surface library that enables designers to easily implement touch pads using the company’s 8-bit PIC® and AVR® microcontrollers (MCUs) and 32-bit SAM MCUs. Available free of charge with the purchase of any compatible MCU, the library provides a simplified, low-cost solution for embedded applications.

Hexiwear is a wearable development kit for the Internet of Things era. A small and sleek, low-power device packed with sensors to quantify yourself and the world around you. Wirelessly enabled, it can connect both to devices nearby or to cloud servers far away.

The winners of the Elektor ESP32 Design Contest 2018 are known! After many hours of wading through project descriptions, watching videos and reading source code, the top 10 of the best projects has been established. What a difficult task it was for the jury with so many high-quality projects contesting for the fantastic prizes. And the Grand Prize has been awarded to...

The STM32L4R9I-EVAL board from STMicroelectronics is intended as a demonstration and development platform for their Arm-Cortex-M4-based STM32L4R9AI microcontroller. Besides the size of the board and the many components that populate it, the user’s attention and curiosity are immediately drawn by the unusual 30 mm (1.2”) circular smartwatch display just below the centre. This is more or less the star of the board, while the MCU itself is so unobtrusive that it is easy overlooked.

If you want to win one of the great prizes of our ESP32 Design Contest, then now is your chance, or, more accurate, your LAST opportunity as there is only one week left to terminate your project and post in at Elektor Labs. The more you publish the better your chances of becoming an ESP32 hero. Source code, schematics, videos and photos, and of course a clear description is what makes a project stand out. Don’t forget to click the red Publish button at the top of your project page! The deadline is March 31 @ 23:59:99999 CET (i.e. midnight in Central Europe).
