Learning Rust For Embedded Systems
The Motivational PortionBased on recommendations from Kevin Nause, the VolksEEG project is considering using Rust as the embedded system programming language. So I've been off on a tear skimming books and e-books and watching videos at 2x to evaluate it.
My conclusion? Do it!
Most of the rest of us participants are primarily C/C++ embedded developers. I had previously been sensitized to Rust for embedded systems by
VolksEEG Project: Initial Hardware Architecture
The initial hardware architecture for the prototype VolksEEG uses an Adafruit Feather nRF52840 Sense, which connects to a PC via USB for UI (User Interface). Through several additional chips, this provides power to and acquires data from the ADS1299 ADC.
An important topic I mentioned in my introduction to the project is isolation, ensuring there is no conductive path for current through the patient. The architecture is therefore split into...
Introducing The VolksEEG Project
IntroductionThe VolksEEG project is an open-source project with the goal of creating an electroenchephalogram (EEG) machine, fully cleared by the FDA for standard clinical use. All designs will be freely available for others to manufacture.
The project was founded by Alan Cohen, a medical device systems engineer with an electrical engineering/software (EE/SW) background in Boston, USA, and Dr. Bryan Glezerson

My Guiding Principles As An Engineer
These are my guiding principles as an embedded systems software engineer, forged over 40 years of experience. They shape the way I work and approach problems, and maintain my attitude in the face of adversity.
You may find them useful as well, whether working as a developer, a manager, or an executive, alone or on a team, when things are going well, and when they aren't.
They're a combination of favorite quotes and my own bits of derivative wisdom I've sprinkled...
Advice For High School Students
ContentsReview: Hands-On RTOS with Microcontrollers
Full disclosure: I was given a free copy of this book for evaluation.
Hands-On RTOS with Microcontrollers: Building real-time embedded systems using FreeRTOS, STM32 MCUs, and SEGGER debug tools by Brian Amos is an outstanding book. It lives up to its name, extremely hands-on and practical, taking you from knowing nothing about RTOS's (Real-Time Operating Systems) up to building real multithreaded embedded system applications running on real hardware.
It uses the ST Micro

One fallout they're experiencing from COVID19 is cancellation of summer internships. This is very unfortunate, because an internship represents maintaining educational momentum and preparing for launch of a career with a taste of the real working world, along with some financial...
Embedded Developers, Ditch Your IDEs – Here’s Why!
Ditching your Integrated Development Environment (IDE) temporarily can be a transformative learning experience in embedded development. This post invites you to explore the underpinnings of IDEs by delving into alternative tools and processes like Makefile, CMake, Vim, GDB, and OpenOCD. Understanding these tools can demystify the background operations of IDEs, revealing the intricacies of compiling, linking, and debugging. This journey into the “under the hood” aspects of development is not just about learning new tools, but also about gaining a deeper appreciation for the convenience and efficiency that IDEs provide. By stepping out of your comfort zone and experimenting with these alternatives, you can sharpen your skills, enhance your knowledge, and possibly discover a more tailored and streamlined development experience. Whether you're a novice or a seasoned developer, this exploration promises insights and revelations that can elevate your embedded development journey.
Embedded Systems - free EdX course by UT-Austin!
I was very excited to see that there will be an Embedded Systems class available for free at https://www.edx.org/course/utaustin/ut-6-01x/embedded-systems-shape-world/1172
It's free to sign up and take the online class at the EdX website.
More exciting is that the class is based on a TI Launchpad Tiva microcontroller development board. The Tiva Launchpad features an 80-MHz ARM Cortex M-4 MCU with 256 KB of flash storage, 32 KB of RAM and 43 general purpose I/O pins.

A Sneak Peek at the 2024 Embedded Online Conference
The embedded systems industry is evolving at a rapid pace. Just a few years ago, most embedded products were disconnected systems that used bare-metal scheduling techniques. Today, the drive to connect devices and add intelligence at the edge is revolutionizing how we build embedded products. The only way to stay current and not get left behind is to learn and network with colleagues and industry experts continuously.
This year, the 2024 Embedded Online Conference is...

Tenderfoot: Recommended Reading
Twenty years ago I read Code Complete by Steve McConnell. And then read it again. And again. And again. Of all the books I have read during my career, I believe this was the book that catapulted me from a young electrical engineer to a young and aspiring embedded software engineer. So to all the ‘tenderfoots’ embarking upon an embedded systems and especially embedded software and firmware career, this entry is for you.
First, I would certainly recommend that all engineers read and read...

Five ‘80s Movies that Inspired Me to Become an Engineer
Five ‘80s Movies that Inspired Me to Become an Engineer
Movies and pop culture can incredibly impact society, particularly children. However, we never really know what conversation, demonstration, or movie could inspire someone to become an engineer. Recently in the Beningo house, we ran out of the film to watch for movie night. In desperation, I decided to find great movies from my childhood in the 80s. To my surprise, I realized how influential several of these films inspired me to...
