One of our clients asked us to help them create a flexible logging library that would work on an Arduino. They were interested in the ability to control formatting and route the output to different endpoints, such as an SD card and over Bluetooth. We documented the process of creating this library, showing how it evolved …

We've worked on numerous embedded projects which avoid the use of printf() due to concerns about binary size bloat. Instead, teams will create their own printf alternative. A classic example is the Arduino SDK's Print class, which requires users to split print statements into multiple function calls to support different variable display formats. We just …

I was asked by a client write a logging library for a project using the Arduino SDK. Since the library will be open-source, I’m going to run an experiment and document the design, development, and feedback cycles on this project. My hope is to expose readers to a real development process, so you can see …

We've worked on numerous embedded projects which avoid the use of printf() due to concerns about binary size bloat. Instead, teams will create their own non-standard printf alternative. A classic example is the Arduino SDK's Print class, which requires users to split print statements into multiple function calls to support different variable display formats. Rather …

The Boost Safe Numerics library, created by Robert Ramey aims to enforce correct mathematical operations with the C++ language. Why are safer numeric operations needed? C++ inherited the behavior of the integral types (int, unsigned, long, etc.) from the C language, where they were designed to map closely to the underlying processor hardware. The types …

We've been hard at work on our C++ embedded systems framework. A critical design requirement is that the framework core components do not utilize dynamic memory allocation. Unfortunately, this excludes most of the STL containers, as they get storage from the heap by default. Rather than reinventing the wheel, we spent some time searching for …

EMB2 is a C/C++ framework developed by Siemens and the University of Houston. EMB2 provides generic building blocks for building multi-core or multi-chip embedded applications, including basic parallel algorithms, concurrent data structures, and application skeletons. Since EMB2 is targeted for embedded applications, it provides soft-real-time support, predictable memory consumption (no dynamic memory allocations after startup), …

The crect project (pronounced correct) is a C++14 library for generating a scheduler for Cortex-M microcontrollers at compile-time. crect uses the Cortex-M's Nested Vector Interrupt Controller (NVIC) to implement a Stack Resource Policy (SRP) scheduler which guarantees deadlock-free and data-race-free execution. crect is built upon the Kvasir Meta-programming Library, which is also the foundation of …
