Interfacing Lua with Existing C/C++ Code
When working with embedded devices, Lua can interface with lower-level C code through Lua bindings. For device management, export the necessary C functions.
Here’s a breakdown of the process:
- Lua Binding: This bridge connects the Lua virtual machine to native C functions or C++ methods, allowing you to call C functions within Lua scripts and add custom functions.
- Manual or Automatic Creation: Lua bindings can be created manually or automatically using tools like the online Lua Binding Generator.
- Compilation: The provided examples include C code demonstrating how to extend Lua APIs. This code can be compiled directly from this web page using the TCC compiler on Windows and GCC on other platforms.
Refer to the figure below for a visual representation of generating and integrating a Lua binding into your firmware. The C code examples also illustrate this process and can be compiled directly from this page.
Install Required Modules
The Lua binding examples require the Mako Server module plugin and a compiler. Click the following button to install the required components.
