📃 C++ Templates for Embedded Code Templates are a powerful feature of the C++ language but their syntax can be complex. This causes some developers to not use them, while others are concerned that templates might cause bloat to the compiled code. The author explains how templates work and how you may use them in your code. Although the examples provided are for the Arduino Uno and Adafruit Feather M0, the concepts will work with any platform and with all modern C++ compilers.

📰 Fearing lawsuits, factories rush to replace humans with robots in South Korea In January, a law came into effect called the , which says, effectively, that if workers die or sustain serious injuries on the job, and courts determine that the company neglected safety standards, the CEO or high-ranking managers could be fined or go to prison. Experts and local media say that the law has shaken the heavy industry and construction sectors. Along with pushing the companies to invest to make workplaces safer, they point out, it’s triggered a ramp-up of automation in order to require fewer workers — or, ideally, none at all. “Companies are moving to reduce human labor,” Jung Jin-woo, a Seoul National University of Science & Technology professor who studies occupational safety and has been following businesses’ reaction to the law, told Rest of World. “There’s also hesitation to jump into any high-risk projects.” #news #robots

📰 Artificial Synapses 10,000x Faster Than Real Thing New artificial versions of the neurons and synapses in the human brain are up to 1,000 times smaller than neurons and at least 10,000 times faster than biological synapses, a study now finds. These new devices may help improve the speed at which the increasingly common and powerful artificial intelligence systems known as deep neural networks learn, researchers say. Just as transistors are the core elements of digital computers, so too are neuron- and synapse-like components the key building blocks in analog deep learning. In the new study, researchers experimented with artificial synapses called programmable resistors. In experiments, the scientists found their protonic programmable resistors could perform at least 10,000 times faster than biological synapses at room temperature. Onen says: "Previously the operation timescales were around milliseconds, whereas in this work we achieved nanoseconds." #news #artificial_intelligence

🎬 Making PCBs with 3D printed stencil and UV paint How to use an UV-curable soldermask as an actual etching mask. This process is pretty quick and doesn't require chemicals to develop the etching mask, just UV light and some heat. Pros: ▫️ no chemicals besides the soldermask, isopropyl alcohol and etchant are required ▫️ the stencil completely blocks UV, making it hard to overexpose the board; it also completly passes the UV in uncovered areas, making the exposure faster than with a plastic film ▫️ the stencil is reusable Cons: ▫️ not suitable for fine-pitch components ▫️ requires adding "bridges" to the stencil to keep it from falling apart #video #electronics

📟 Build your own IoT platform using node.js and ESP8266 In this article, you will learn how to build your own IoT minimal platform, that works over the internet. The platform will have three parts: ▫️ The User Interface (frontend) ▫️ Server (backend) ▫️ Hardware And all three parts of the application should be able to communicate with each other in real-time. The obvious protocol for hardware-based products/projects is MQTT. MQTT is a lite weight communication protocol designed to run even on low-power hardware. But today we are NOT USING MQTT, for the sake of simplicity and the cost of running the server. #esp32 #IoT

🎬 Message Handling in Embedded: a Declarative, Modern C++ Approach In embedded systems, messages usually arrive asynchronously and need to be efficiently parsed. Often the structure and semantics of a message packet depend on the value of a series of bits within the message. In event driven designs, messages are filtered and routed to proper handlers. This talk will dive into a declarative approach to solving common problems with message handling: bit mapping fields, filtering, and dispatching to handlers. The solution is sensitive to small footprint embedded targets yet fairly flexible. #video #cpp

Message Handling in Embedded: a Declarative, Modern C++ Approach - Michael Caisse - CppNow 2022
Slides: https://github.com/boostcon CppNow Website: https://www.cppnow.org​ CppNow Twitter: @CppNow​ --- Message Handling in Embedded: a Declarative, Modern C++ Approach - Michael Caisse - CppNow 2022 A common characteristic of embedded systems is that they have a broad interface surface interacting with many distinct devices. Often the interfaces support a message passing protocol. This is true at the device to device level with implementations on I2C, SPI, and CAN as well as deeply embedded systems communicating within a chip package. Messages usually arrive asynchronously and need to be efficiently parsed. Often the structure and semantics of a message packet depend on the value of a series of bits within the message. In event driven designs, messages are filtered and routed to proper handlers. This talk will dive into a declarative approach to solving common problems with message handling: bit mapping fields, filtering, and dispatching to handlers. The solution is sensitive to small footprint embedded targets yet fairly flexible. We will build up the basic idioms employed in the solution, look at some language gotchas and options, and end our spelunking with a performance critique. While the application is for a deeply embedded device, the message handling is applicable to bit-field aggregated message formats and the techniques are useful in declarative libraries. I hope you will join me as we explore this C++17 library. --- Michael Caisse --- Videos Filmed & Edited By Bash Films https://bashfilms.com/ YouTube Channel Managed By Digital Medium Ltd: https://events.digital-medium.co.uk #Boost​ #Cpp​ #CppNow​

📟 ESP32 powers IoT Geiger counter Since the war in Ukraine, the discussion about nuclear weapons raised and people got into thinking about radioactive exposure again. While there is no real fear, there is still some awareness and interest in the normal radiation levels you have around you all the time. The main sensor is represented by Soviet-era SBM-20 Geiger–Müller tube. That meant coming up with a new high-voltage power supply capable of providing the tube with the necessary 400 V, which from the sound of things, took a few attempts to complete. The final result is perhaps the smallest and cleanest looking board we’ve ever seen play host to this particular tube. To run the show, author selected the ESP32-PICO-D4. It reads the impulses from the SBM-20 tube and publish them via MQTT.

🎚 Raspberry Pi Pico W – A $6 board with WiFi 4 Fast cores, large memory, and flexible interfacing make RP2040 a natural building block for Internet of Things (IoT) applications. But Pico itself has one obvious missing feature for IoT: a method for connecting to the network. Now, this is about to change. Raspberry Pi Pico W is priced at $6, and brings 802.11n wireless networking to the Pico platform, while retaining complete pin compatibility with its older sibling. Like the original Raspberry Pi Pic, the new board supports both C programming and MicroPython, but the Raspberry Pi Pico W comes preloaded with MicroPython. Programming is about the same, except for the additional Wi-Fi API.

💻 How to Debug an Arduino Project Debugging is a vital element of the creative process when it comes to developing code. However, Arduino debugging, can be difficult as the Arduino IDE does not include a specialized debugging tool. ▫️ Arduino IDE Pro has a debugging tool that can be used to enhance debugging skills. It has the following features which make it very useful to the developers: code indentation, block folding, auto-closing brackets, comment toggling, etc. ▫️ Visual Micro is a Microsoft Visual Studio plugin that allows you to develop cross-platform Arduino applications. Visual Micro also provides GDB debugging, as well as serial, Bluetooth, and Wi-Fi debugging. ▫️ DebugWire is an Atmel protocol that allows you to debug multiple ATTiny (e.g., ATTiny 13, 85) and ATmegas (e.g., ATmega48/88/168/328) without using JTAG and just using the Reset pin. ▫️ Atmel Studio IDE is a free environment that provides competitive debugging capabilities to assist in the resolution of code problems. #articles

📃 What are best practices for IoT system security? reached out to experts on their best practices: ▫️ The latest software is the most secure. That’s because it addresses currently known threats (CVEs or Common Vulnerabilities and Exposures). CVEs are fixed first upstream (for open source) and in new software releases for proprietary software. ▫️ Open-source platforms are open to scrutiny and continually updated to counter latest threats. ▫️ A unique Root of Trust should be installed on every device ▫️ ALL software on an end device should be updatable - we don't know what we don't know as we learned with Spectre and Meltdown. This includes secure boot firmware on Arm and BIOS on x86. ▫️ Device provisioning should be simple and not involve the end user. This means secure device onboarding.

🎚 Khadas VIM4 Review: Faster Than a Raspberry Pi There have been many pretenders to the Raspberry Pi’s crown, some good and some bad. But none have managed to throw the Raspberry Pi offs its throne as the go-to single board computer for projects. Khadas’s VIM4 is the latest to make the attempt and it comes so close. The Khadas VIM4 is an octa-core Arm CPU package with a quad-core Arm Cortex A73 running at up to 2.2 GHz, and a 2-GHz Arm Cortex A53. This is backed up with 8GB of LPDDR4X running at 2016 MHz. But there is something else with the Khadas VIM4. Hidden under the flat heatsink is a 32GB eMMC 5.1 chip which gives us better performance than a micro SD card. The downside of this Khadas VIM4 is the GPIO. We would love to see full access via Python and other programming languages. Once we have that, then the Khadas VIM4 will be “on par” with the features of the Raspberry Pi, though it will never have the level of support and huge ecosystem of the Pi.
