RT-Thread Layers

RT-Thread software layers

• Kernel layer: the implementation of objects in kernel system including multi- threading and its scheduling, semaphore, memory management, timer, etc.

• Components and Service Layer: modular design components, such as virtual file systems, FinSH command-line interfaces, network frameworks, etc.

• RT-Thread software package: general-purpose software components running on the RT-Thread IoT operating system platform for different application areas.

Software components

• FinSH Console is the command line component of RT-Thread.

• Device File System (DFS) is a device virtual file system using a style similar to UNIX files and folders.

• Socket Abstraction Layer (SAL) abstracts different network protocol stacks or network implementations using a set of standard BSD Socket APIs.

• Dynamic module (dlmodule) provides a mechanism for dynamically loading program modules for RT-Thread. At runtime, the compiled dynamic modules are loaded into the kernel through the module loader in the kernel.

Software development tools

• RT-Thread Studio has the features of project creation and management, code editing, SDK management, RT-Thread configuration, build configuration, debugging configuration, program download and debug.

• ENV provides a build environment, graphical system configuration, and package management capabilities for RT-Thread project.
