Simply copy the `fbgl.h` file into your project dir Here’s a simple program that initializes the framebuffer, clears it to a blue color, and draws a red diagonal line. ```c -#include <stdio.h> #include "fbgl.h" +#define FBGL_IMPLEMENTATION +#include <stdio.h> + +int main() +{ + + fbgl_t buffer; -int main() { // Initialize the framebuffer - if (fbgl_init("/dev/fb0") != 0) { + if (fbgl_init("/dev/fb0", &buffer) != 0) { fprintf(stderr, "Failed to initialize framebuffer\n"); return 1; } - printf("Framebuffer size: %dx%d\n", fbgl_get_width(), fbgl_get_height()); + printf("Framebuffer size: %dx%d\n", fb_get_width(), fb_get_height()); // Clear framebuffer to blue fbgl_clear(0x0000FFFF); // Blue color // Draw a red diagonal line - for (int i = 0; i < fbgl_get_width() && i < fbgl_get_height(); i++) { - fbgl_put_pixel(i, i, 0xFFFF0000); // Red + for (int i = 0; i < fb_get_width() && i < fb_get_height(); i++) { + fbgl_put_pixel(i, i, 0xFFFF0000, &buffer); // Red } // Wait for user input before exiting getchar(); // Clean up - fbgl_destroy(); + fbgl_destroy(&buffer); return 0; } ``` |
