Using Modern C++ Techniques with Arduino

C++ has been quickly modernizing itself over the last few years. Starting with the introduction of C++11, the language has made a huge step forward and things have changed under the hood. To the average Arduino user, some of this is irrelevant, maybe most of it, but the language still gives us some nice features that we can take advantage of as we program our microcontrollers.

Modern C++ allows us to write cleaner, more concise code, and make the code we write more reusable. The following are some techniques using new features of C++ that don’t add memory overhead, reduce …read more

FreeRTOS Gets Class

[Michael Becker] has been using FreeRTOS for about seven years. He decided to start adding some features and has a very interesting C++ class wrapper for the OS available.

Real Time Operating Systems (RTOS) add functionality for single-thread microcontrollers to run multiple programs at the same time without threatening the firmware developer’s sanity. This project adds C++ to the rest of the FreeRTOS benefits. We know that people have strong feelings one way or the other about using C++ in embedded systems. However, as the 24 demo projects illustrate, it is possible.

One nice thing about the library is that …read more

Toyota’s Code Didn’t Meet Standards and Might Have Led To Death

We were initially skeptical of this article by [Aleksey Statsenko] as it read a bit conspiratorially. However, he proved the rule by citing his sources and we could easily check for ourselves and reach our own conclusions. There were fatal crashes in Toyota cars due to a sudden unexpected acceleration. The court thought that the code might be to blame, two engineers spent a long time looking at the code, and it did not meet common industry standards. Past that there’s not a definite public conclusion.

[Aleksey] has a tendency to imply that normal legal proceedings and recalls for design …read more
