💻 3 Common Challenges Facing RTOS Application Developers
It is critical to address these items to successfully exploit the benefits of real-time operating systems.
▫️ Selecting Task Priorities
The most common challenge I see and am asked about is a fairly fundamental one; how to select the right priorities for tasks. It turns out that there are several different ways to select task priority.
▫️ Seeing the Big Picture with a Dataflow Diagram
I often encounter developers who are implementing their RTOS application without really understanding where data is being produced, where it is going, and how it is getting there. This results in software that is a bit spaghetti code-like and often requires constant rework as more application pieces are put in place.
▫️ Properly Protecting Shared Memory
A mutex is used to protect the shared memory resource but in the implementation, I often see developers create the mutex separately from the data that is being protected.

📟 3D-printed Mini Hygrometer with ePaper display & Bluetooth
The build runs on an nRF52811 microcontroller, hooked up to a 1.02″ ePaper display sourced for just $7. A SHT20 temperature and humidity sensor is then queried to sample the ambient conditions, and the results displayed on the screen. The benefit of this is that the device can be powered from a coin cell, and set to update at infrequent intervals – say, once per hour. It can then be checked by the user without having to turn on.
The low-power design means it would be the perfect device for leaving in a guitar case or humidor for months at a time. As a bonus, it’s also capable of Smart Home integration thanks to the Bluetooth capabilities onboard.

+1🎙 The development of USB microphone
"Any normal person would open Amazon and either buy the cheapest microphone available, or perhaps a Røde if they know decent audio when they hear it. Not me though. This sounds like a project if ever I heard one. A good chance to see if I can build a USB microphone and learn a thing or two along the way."
Extremely detailed article describing the process of development of a USB microphone for online meetings from the scratch.
The author has shown how to set up requirements for the project, design electrical circuit, choose components, develop PCB and write code for the board.

🔦 Acoustic Tractor Beam
Tractor Beams are mysterious waves that can attract particles towards the source. Here, we will show you how to build an Acoustic Tractor Beam with components that can be bought directly on the Internet for less than 75$.
The circuit is not complicated. Basically, an Arduino will generate 4 half-square signals at 5Vpp 40kHz with different phases. These signals get amplified to 25Vpp by the Motor Driver and fed into the transducers. A button pad can be used to change the phases so that the particle moves up and down. A battery (7.3V) powers the Arduino and the logic part of the Motor Driver. A DC-DC Converter steps-up the 7.3V to 25V for the Motor Driver.

🎚 PD controller's visualization
A proportional-derivative (PD) controller can be used to make a simple system track some reference point. The suspension in a car is an analogue example: the spring and damper work together to hold the car at some desired height. The spring exerts a force proportional its deflection, while the damper opposes motion (the derivative of deflection).
A PD controller uses the same principles to create a virtual spring and damper between the measured and reference positions of a system.
The provided link shows good analogy between physical system and PD controller and helps to understand how PD controller works in reality.

🤖 Arduino Controlled Robotic Biped
The primary goal while building this project was to make the system as robust as possible such that while experimenting with various walking and running gaits, I wouldn't have to constantly worry about the hardware failing. This allowed me to push the hardware to its limit.
A secondary goal was to make the biped relatively low-cost using readily available hobby parts and 3D printing leaving room for further upgrades and expansions. These two goals combined provide a robust foundation to perform various experiments, letting one develop the biped to more specific requirements.

🎛 ESP32 OTA (Over-the-Air) Updates
In this guide, you’ll learn how to do over-the-air (OTA) updates to your ESP32 boards using the AsyncElegantOTA library. This library creates a web server that allows you to upload new firmware (a new sketch) to your board without the need to make a serial connection between the ESP32 and your computer.
Additionally, with this library, you can also upload new files to the ESP32 filesystem (SPIFFS). The library is very easy to use, and it’s compatible with the ESPAsyncWebServer library that we often use to build web server projects.

🎚 Fuzix on the Raspberry Pi Pico (update - March 10 2021)
"I’ve finally finished (or at least, made feature complete) my Raspberry Pi Pico Fuzix Port. This is a proper V7 Unix clone which will run on the Raspberry Pi Foundation’s $4 microcontroller board.
This now requires no extra hardware to run! You can use it with a UART or an SD card. Just plug your Pico in via USB, flash it, and it’ll work."
This has a tonne of new features compared to the previous version:
▫️ 160kB of user RAM, enough for four or five processes in-memory with proper (cooperative) multitasking
▫️ 1.2MB root filesystem on the internal flash - no SD card necessary
▫️ optional swap, if you want it
▫️ USB CDC serial port support, so you don’t need a UART adapter any more

📊 Embedded Software Trends Expand in 2020
Preferred languages, machine learning for 3rd graders, spaceship software, GIT, outdated IP and other embedded software trends emerge.
A recent study in 2020 by Northeastern University confirms the popularity of Python, Java, and C/C++. The study notes that Python is widely regarded as a programming language that’s easy to learn, due to its simple syntax, a large library of standards and toolkits, and integration with other popular programming languages such as C and C++.
The second game-changing trend in the embedded space on Beningo’s list was machine learning, especially for IoT edge applications. As he pointed out, machine learning holds a lot of potential for embedded systems developers as the new decade begins.
Version control and management of intellectual property (IP) have become a necessity for mission-critical and non-mission-critical applications.

🎚 Software Defined Radio (SDR) on Low Cost Raspberry Pi Pico
In the latest project to grab our attention, we see Luigi Cruz, a computer student and amateur radio enthusiast, use the Pico as a software defined radio (SDR) interface for the popular GNR Radio application.
Cruz's SDR project, PicoSDR, uses one of the analog input pins to sample 8 bit data at 500ksps. Cruz has connected the Pico's analog input to the output of his soundcard and uses an online tool to generate tones that are visible on his computer. To connect the Pico to the computer, Cruz explains, "The data is sent via USB using the RNDIS protocol to emulate a TCP/IP interface. The ADC speed is limited to 500 ksps. The data can be used with software like the GNU Radio with a custom block." This provides a low-bandwidth means to get data from the Pico and into applications such as GNU Radio.

📄 3 Advantages To Using A Multicore Microcontroller
Multicore microcontrollers undoubtedly provide development teams with many advantages to help them solve the problems with ever more complex systems.
The ability to separate the application into areas of concerns or domains is currently a leading driver for adopting multicore microcontrollers.
The ability to balance performance with energy consumption and distribute the workload are also major advantages when considering moving to a multicore solution.
While there are only a few multicore microcontrollers currently on the market, over the next decade we will undoubtedly find them in ever increasing numbers in our designs.

📄 Comparing Optimal Control and Reinforcement Learning Using the Cart-Pole from OpenAI Gym
The idea of autonomous systems excites me and applying reinforcement learning to everything to achieve autonomy seems tempting. But it is not always that easy and using optimal control might sometimes be the better solution.
What I do want to demonstrate in this post are the similarities (and differences) on a high level of optimal control and reinforcement learning using a simple toy example, which is quite famous in both, the control engineering and reinforcement learning community — the Cart-Pole from OpenAI Gym.
I will start off briefly covering the Cart-Pole and then go into more detail about an optimal control approach to solving the task and its implementation using Python and end with a short discussion. So let’s go!

🖨 ESP8266 ESC/POS Smart Thermal Printer
[Davide Gironi] has built his own note transcriber from a point-of-sale receipt printer and an ESP8266.
You’ve seen these receipt printers at the order window of restaurants. A server puts in an order from any of the machines throughout the restaurant and a paper summary spits out for the chef line to start in on (and even cuts itself off from the roll). Why shouldn’t we have this convenience in our own lives?
The printer communicates using a variant of the Epson Standard Code for Printers, for which [Davide] has written a library and thankfully shared the code. Adding an ESP8266 using a couple voltage regulators and some passive components makes this wireless, except for power. It has all the fun bells and whistles to set up the Wi-Fi credentials and once running, just push the button on the base and it’ll spit out your data.
