In this article, we will cover the main features and benefits of STM8 IAR 1.4, how to download and install it, how it compares with other compilers, and some frequently asked questions about it. By the end of this article, you will have a clear idea of why STM8 IAR 1.4 is a great choice for your embedded projects.


Features and Benefits of STM8 IAR 1.4




STM8 IAR 1.4 offers a complete set of tools for developing high-quality code for STM8 microcontrollers. Here are some of the key features and benefits of this toolchain:


User-friendly IDE with project management tools and editor




The IDE of STM8 IAR 1.4 provides one toolbox in one view, giving you one uninterrupted workflow. You can easily create, manage, build, debug, and analyze your projects using the intuitive graphical interface. The IDE also includes linker and library tools, example projects, and code templates to help you get started quickly.


Powerful build tools with highly optimizing C/C++ compiler




The IAR C/C++ Compiler is a highly optimizing compiler for STM8 devices that generates smaller, faster, and smarter code. It offers configuration files for all STM8 devices, relocating STM8 assembler, and run-time libraries. It also supports various language extensions such as inline assembly, bit fields, named address spaces, pragmas, etc.


Comprehensive debugger with simulator, RTOS-aware debugging, and support for STice Emulator and ST-Link debug probe




The C-SPY Debugger provides a powerful debugging functionality for STM8 devices. It supports a simulator that allows you to test your code without hardware connection. It also supports RTOS-aware debugging with built-in plugin for OSEK Run Time Interface (ORTI). Moreover, it supports STice Emulator system and ST-Link debug probe for hardware debugging.


Integrated code analysis Integrated code analysis with C-STAT for code quality and compliance with standards




C-STAT is a static analysis tool that is used to identify the deviations from certain coding rules by doing one or more checks for the rule. The checks are grouped into packages. The various packages are listed below:



Package


Description


MISRA C:2012


Checks for compliance with the MISRA C:2012 coding standard, which aims to facilitate the development of safe and secure embedded systems.


MISRA C++:2008


Checks for compliance with the MISRA C++:2008 coding standard, which provides guidelines for the use of C++ in critical systems.


MISRA C:2004


Checks for compliance with the MISRA C:2004 coding standard, which is a previous version of the MISRA C:2012 standard.


CERT C/C++


Checks for compliance with the CERT C/C++ Secure Coding Standards, which provide rules and recommendations for secure coding in C and C++.


CWE


Checks for common weaknesses and vulnerabilities in C and C++ code, as defined by the Common Weakness Enumeration (CWE) initiative.


IAR Systems


Checks for potential issues and best practices related to the use of IAR Embedded Workbench and IAR C/C++ Compiler.


C/C++ Core


Checks for general issues and best practices in C and C++ code, such as syntax errors, memory leaks, buffer overflows, etc.


C-STAT is fully integrated with the IAR Embedded Workbench IDE and enables you to easily ensure code quality in your daily development flow. You can configure which packages and checks to enable or disable, and view the analysis results in the IDE. You can also generate reports in HTML or XML format. C-STAT provides you with comprehensive and detailed error information, including the rule number, description, severity level, location, and possible remediation.


On-demand training included with license purchase




When you purchase a license for STM8 IAR 1.4, you also get access to on-demand training courses that will help you to get the most out of the toolchain. The courses cover topics such as getting started with STM8 IAR 1.4, using the IDE features, optimizing code size and speed, debugging techniques, using C-STAT, etc. The courses are self-paced and interactive, and include quizzes and exercises to test your knowledge. You can access the courses anytime and anywhere through the IAR Academy portal.


Comparison with Other Compilers




STM8 IAR 1.4 is not the only compiler available for STM8 devices. There are other alternatives such as Cosmic STM8 Compiler, Raisonance STM8 Compiler, SDCC (Small Device C Compiler), etc. How does STM8 IAR 1.4 compare with these compilers in terms of standard compliance, code size, code speed, and debugging functionality? Let's take a look at some of the advantages and disadvantages of STM8 IAR 1.4 over other compilers.


Advantages of STM8 IAR 1.4





  • STM8 IAR 1.4 is fully compliant with ISO/IEC 9899:1999 (C99) and ISO/IEC 14882:2003 (C++03) standards, as well as various language extensions. It also supports embedded-specific features such as named address spaces, bit fields, pragmas, etc.



  • STM8 IAR 1.4 generates smaller and faster code than other compilers, thanks to its highly optimizing compiler technology. It also offers various optimization options and strategies that can be tailored to your specific needs.



  • STM8 IAR 1.4 provides a comprehensive debugging functionality that supports both simulation and hardware debugging. It also supports RTOS-aware debugging with ORTI plugin. It supports STice Emulator system and ST-Link debug probe for hardware debugging.



  • STM8 IAR 1.4 includes an integrated code analysis tool (C-STAT) that ensures code quality and compliance with standards such as MISRA C:2012, MISRA C++:2008, MISRA C:2004, CERT C/C++, and CWE.



  • STM8 IAR 1.4 includes on-demand training courses that help you to learn how to use the toolchain effectively and efficiently.



Disadvantages of STM8 IAR 1.4





  • STM8 IAR 1.4 is not a free or open source compiler. It requires a license purchase and a yearly maintenance fee to get support and updates. The license cost depends on the number of users, the license type (node-locked or floating), and the license duration (1 year, 3 years, or perpetual).



  • STM8 IAR 1.4 does not support some of the newer C and C++ standards, such as C11, C18, C++11, C++14, C++17, and C++20. It also does not support some of the newer STM8 devices, such as STM8AF6x and STM8AL3x.
