A custom VGA driver compatible with x86 kernels, along with a simple graphics library (SGL) designed to provide basic drawing capabilities on VGA-compatible displays. The driver interfaces directly with VGA hardware, providing low-level access to manipulate the display buffer and control the screen output. The graphics library built on top of the driver offers functions for drawing basic shapes and handling colors.
- Low-level VGA driver for interfacing with VGA-compatible displays.
- Double buffering for reducing flickering and screen tearing.
- Support for setting display modes, manipulating display buffer, and controlling screen output.
- Simple graphics library built on top of the VGA driver.
- Drawing functions for basic shapes (lines, rectangles, circles and triangles).
- Support for handling colors and basic color manipulation.
- Development Environment: Set up a development environment with a compatible toolchain, such as NASM for assembly and GCC for C code.
Example Usage:
#include "vga.h"
#include "sgl.h"
void main() {
vgaInitGfxMode(MODE13H);
sglClear();
sglDrawRect(150, 10, 100, 50, GREEN);
sglDrawLine(120, 14, 24, 30, RED);
sglDrawCircle(100,100,50, CYAN);
sglDrawFilledTri(100, 100, 50, 150, 120, 120, MAGENTA);
sglDrawTri(200, 100, 150, 170, 250, 190, YELLOW);
for (int i = 0; i < 15; i++) {
for (int j = 0; j < 100; j++) {
sglPutPixel(i, 50 + j, i);
}
}
sglSwapBuffers();
