Embedded Systems in Elixir vs. C, C++, and Java with Connor Rigby & Taylor Barto

This week on Elixir Wizards, Connor Rigby, Software Engineer at SmartRent, and Taylor Barto, Lead Embedded Software Engineer at Eaton, join Sundi Myint to compare notes on embedded systems development with Elixir, C, C++, and Java. They discuss using Elixir and the Nerves framework for firmware projects versus more traditional choices like C. The guests ask one another questions and gain valuable insights into challenges, tooling, resources, and more across different embedded ecosystems.
In this episode, the guests expand their perspectives and demystify the concept of embedded systems for engineers outside the field. This cross-language exchange of ideas and experiences inspires continued learning and collaboration between embedded software engineers using different programming languages.
Topics Discussed:
Defining "true embedded": using an operating system vs. bare metal programming
Benefits and drawbacks of Elixir, C, C++, and Java for firmware
Many embedded systems today use Java as the programming language via Java Native Interface (JNI) to interface with C/C++ code
How Elixir expands the toolbox available for firmware projects
Testing, tooling, workflows, and debugging across languages
Elixir/Nerves features like hot code reloading and testing vs. Java alternatives
Learning curves for new languages and frameworks
Industry trends around established vs emerging tools
Applying functional programming principles like immutability in new domains
Scaling firmware updates across large connected networks
Continued maturation of Nerves may bring Elixir into consideration for roles where Java is commonly used today
Hardening systems for reliability in safety-critical uses
Debugging differences between web development and embedded
Hiring considerations for niche languages
Additional skills needed for embedded engineers, such as technical writing, reading schematics, and writing test instructions
Resources and recommendations for getting started with embedded systems
