MISRA C
MISRA C is a set of software development guidelines for the C programming language, primarily aimed at ensuring safety, reliability, and portability in embedded systems and other critical applications. It provides rules and directives to avoid unsafe coding practices, reduce errors, and improve code maintainability, often used in industries like automotive, aerospace, and medical devices. The guidelines are maintained by the MISRA (Motor Industry Software Reliability Association) consortium and are periodically updated to address evolving standards and practices.
Developers should learn and use MISRA C when working on safety-critical systems where code reliability and defect prevention are paramount, such as in automotive software (e.g., for engine control units or braking systems) or avionics. It helps comply with industry standards like ISO 26262 for automotive functional safety and reduces risks of bugs that could lead to system failures or safety hazards. Adopting MISRA C is also beneficial for improving code quality and team consistency in large-scale embedded projects.
