Preparing for the Future of Embedded C Programming: An Overview of the Upcoming ISO/IEC 9899:2023 C Standard

The ISO/IEC 9899:2023 C programming standard (C23) has been finalised and is set to release in the near future, and it is expected to bring several changes and improvements to the language. This talk is specifically aimed at embedded C programmers, who will benefit from understanding the changes in the upcoming standard.
The talk will begin by providing an overview of the significant changes and improvements that the new standard will introduce (with a quick review of C11 and C18) of interest to the embedded programmer. Many changes include an aim to “harmonize” with modern C++ and improve code interoperability. The presentation will also cover the potential challenges and issues that embedded C programmers may face when migrating to the new standard. This will include an overview of the potential compatibility issues and the need to update existing code and development practices.
The talk will conclude by highlighting the benefits that embedded C programmers can expect from adopting the new standard, including increased reliability, and reduced development time and costs.
The overall goal of the presentation is to provide embedded C programmers with a comprehensive understanding of the upcoming changes to the C programming language and how it will impact their work.
