Bodmer/TFT_eSPI

Features

• TFT Display Drivers - Serves as a comprehensive graphics library and driver for various TFT displays across multiple microcontroller architectures.
• Embedded Display Drivers - Provides low-level firmware for controlling various TFT screen driver chips via SPI or parallel interfaces.
• Embedded - Enables the creation of visual user interfaces with anti-aliased shapes and flicker-free graphics on microcontrollers.
• Anti-Aliasing Techniques - Provides a rendering engine that uses anti-aliasing to create smooth shapes and fonts without jagged edges.
• Rasterization Techniques - Implements a rendering system that calculates sub-pixel coverage to eliminate jagged edges in shapes and fonts.
• Embedded Graphics Engines - Uses DMA and PIO hardware to accelerate image transfers and render compressed PNGs on resource-constrained devices.
• Anti-Aliased - Renders arcs, circles, lines, and rounded rectangles using anti-aliasing to eliminate jagged edges.
• Off-Screen Rendering - Renders graphics to a dedicated off-screen RAM buffer before pushing them to the screen to prevent visual flickering.
• Hardware Abstraction Layers - Provides a unified API that translates generic drawing commands into chip-specific instructions for various driver ICs.
• Touch Controller Integration - Integrates and processes input from SPI-based touch screen controllers to enable user interaction.
• DMA-Capable Drivers - Utilizes direct memory access to transfer image data to the display, significantly increasing frame rates.
• Low-Latency Pixel Transfers - Utilizes direct memory access for high-speed, low-latency pixel transfers to the display hardware.
• Anti-Aliased Typography - Displays high-quality typography using custom font files that support Unicode characters and anti-aliasing.
• Frame Buffers - Implements off-screen RAM buffers for graphics rendering to eliminate visual flickering during screen updates.
• Unicode Typography Renderers - Draws proportional and Unicode characters to the screen using various sizes to support multiple languages.
• Image Decoding - Decodes and renders PNG compressed images directly onto the visual display.
• Real-Time Image Decoding - Decompresses image data in real time from storage and renders it directly to the display buffer.
• Parallel Communication Interfaces - Transmits pixel data across multiple 8-bit hardware lines to increase throughput compared to serial communication.
• Parallel RGB Display Connections - Implements 8-bit parallel communication to drive displays, providing an alternative to serial SPI interfaces.
• SPI Bus Drivers - Coordinates the use of a single SPI bus for both a display and an SD card reader.
• Bus Arbitration - Manages a single SPI interface by toggling chip-select pins to coordinate between a display and an SD card.
• Bus-Sharing Arbitration - Coordinates a single SPI bus to be shared between the TFT display and an SD card reader.
• Display Data Acceleration - Increases frame rates by using DMA controllers to move image data directly to the display hardware.
• Touch Controller Drivers - Provides a hardware abstraction layer to integrate and retrieve coordinates from SPI-based touch screen controllers.
• Touch Event Processors - Processes raw touch events from SPI controllers to enable interactive user interface elements.
• Typography Smoothing - Displays anti-aliased text using block-by-block updates to reduce flicker during rapid value changes.
