The following are some of the main tool categories commonly used in embedded development and their representative products:
Integrated Development Environment (IDE)
Keil MDK (Microcontroller Development Kit): Designed for embedded systems based on microcontrollers such as ARM Cortex-M, Cortex-R4, and Cortex-R5, it integrates uC/OS-II real-time operating system support and provides a one-stop development solution, including compiler, debugger, and project management tools.
IAR Embedded Workbench: It widely supports a variety of embedded processors and is known for its high-performance compiler and debugger, making it particularly suitable for resource-constrained embedded system development.
Eclipse with CDT (C/C++ Development Tools): This is an open-source, general-purpose IDE platform that supports embedded development by installing specific plugins. For example, it can be used with the GNU ARM Eclipse plugin to perform embedded development on the ARM architecture.
Visual Studio Code with PlatformIO**: VS Code is a lightweight yet powerful code editor. With the PlatformIO extension, it can become a cross-platform embedded development IDE, supporting numerous MCU and RTOS platforms.
Cross-compilation toolchain
GNU Arm Embedded Toolchain: This is a free and open-source cross-compilation toolchain maintained by ARM for compiling target code for the ARM architecture on host platforms.
GCC for MIPS, AVR, RISC-V, etc.: The GNU Compiler Collection provides cross-compilers for different embedded architectures, allowing developers to build applications for different types of embedded chips based on these toolchains.
Emulators and Debuggers
J-Link, ST-LINK, and OpenOCD are all hardware debuggers that connect to the debugging interface on the embedded target board. They allow developers to debug software code in the embedded system on the host machine, enabling functions such as breakpoint setting, memory viewing, and CPU status monitoring.
Simulators, such as QEMU, can simulate the operating environment of an embedded system without real hardware, facilitating initial software verification and debugging.
Version control system
Git: As the most popular distributed version control system, embedded development teams generally use Git for source code management and version control to ensure a smooth development process and complete historical records under multi-person collaboration.
Building Systems and Continuous Integration Tools
CMake, Make, Ninja: These tools help automate the build process, making the compilation process simpler and more efficient, especially in large projects, and enabling unified management of compilation options and dependencies.
Jenkins, Travis CI, GitLab CI/CD: Continuous integration and deployment tools are equally important in embedded development. They can automatically complete code compilation, testing, packaging, and other tasks, and provide timely feedback on the build results.
Hardware programming and downloading tools
Flash programming tools, such as STM32CubeProgrammer and FLIP (Freescale Flash Programmer), are used to download compiled firmware programs to the flash memory of embedded devices.
Serial terminal tools, such as PuTTY and TeraTerm, are used to communicate with embedded devices via serial ports for online debugging and data transmission.
Static code analysis tools
Cppcheck, PC-lint: These tools can improve code quality and security by scanning code structure and syntax features without actually executing the code.
Graphical User Interface Development Tools
Qt Creator supports not only desktop application development but also GUI application development under embedded Linux systems, providing rich graphical interface elements and cross-platform capabilities.
Testing tools
Unit testing frameworks: such as Unity and CMock are used to write and execute unit tests to ensure module-level correctness.
System testing tools, such as Robot Framework and TestComplete, can simulate user interactions and verify whether the overall functionality meets expectations.
Documents and Collaboration Tools
Doxygen: An automatic documentation generation tool used to extract documentation information from source code comments, facilitating the management and maintenance of project documentation.
Confluence, Slack, Microsoft Teams: These tools facilitate communication and collaboration between teams and make project progress more transparent.
Embedded development tools encompass every stage of the software lifecycle, from coding, building, and debugging to testing, deployment, and maintenance. Each step is supported by specialized tools or software suites, greatly enhancing the productivity and product quality of embedded software development. As technology advances and industry standards change, new tools and platforms are constantly emerging to meet the increasingly complex needs of embedded systems.
