x_gen_link Protocol Stack

Modern, robust, and highly configurable communication protocol stack for resource-constrained embedded systems.

Features

• Multi-instance architecture: Support multiple independent protocol stacks
• Zero-copy optimization: Minimize memory bandwidth and CPU overhead
• Compile-time configuration: Eliminate unused code through Kconfig
• Thread safety: Optional mutex protection for RTOS environments
• Bare-metal support: Run without RTOS dependencies
• Minimal footprint: 32KB RAM, 50KB Flash for basic configuration
• Industrial quality: Comprehensive testing, documentation, and CI/CD

Quick Start

Build

Example Usage

#include <xgl/xgl.h>

int main(void) {
    /* Get default configuration */
    xgl_config_t config;
    xgl_config_get_default(&config);
    
    /* Create protocol instance */
    xgl_handle_t handle = xgl_create(&config);
    
    /* Initialize */
    xgl_init(handle);
    
    /* Use the protocol... */
    
    /* Cleanup */
    xgl_destroy(handle);
    
    return 0;
