🚀 Multi-Platform Support

Native support for ESP32 (ESP-IDF), STM32 (HAL), and Jetson (Linux framebuffer) with unified API

🎯 SPI Display Optimized

Specifically designed for SPI displays including SSD1306, SSD1309, ILI9341, and more controllers

🔧 Modular Architecture

Pluggable display controllers, platform-specific drivers, and reusable UI components

⚡ High Performance

Optimized for real-time embedded systems with minimal memory footprint and fast rendering

🛠️ Easy Integration

Simple CMake integration with ESP-IDF projects and other build systems

📦 Rich Components

Built-in UI components like labels, buttons, rectangles, and custom drawing primitives

Quick Example

cpp

#include "ESP32_SPI_Driver.h"
#include "SSD1309Controller.h"

// Create SPI driver for ESP32
ESP32_SPI_Config config;
config.dc_pin = 1;
config.cs_pin = 2;
config.rst_pin = 0;

auto controller = std::make_unique<SSD1309Controller>(oled_config);
ESP32_SPI_Driver driver(config, std::move(controller));

// Initialize and draw
driver.initialize();
driver.fillRect(10, 10, 50, 30, 1);
driver.display();
