A modular C++ 2D engine for embedded displays and desktop, with a visual editor.

The engine core and its C++ API are here. Packages document themselves, linked below. All of it is generated from the code (engine 0.19.0).

Engine core: components and settings the engine provides itself
Project settings: every settings section, by owner
API reference: the C++ classes of the engine and the editor DLL
Editor repository: setup, contributing, compatibility policy

Packages

Each is its own repository under github.com/dekiengine. Install with DekiEditor --packages-add <id> <project>, or from the Package Manager.

Package	Components	Summary
deki-2d	11	Sprites, text, animations, gradients, buttons, scrolling
deki-3d	2	Software-rasterised 3D as a render pass: meshes, a perspective camera and .obj import, sharing one framebuffer with 2D
deki-audio	1	Audio playback peripheral interface with MAX98357 (I²S) backend
deki-ble	0	Bluetooth Low Energy interface: scanning, advertising, GATT server, connections
deki-desktop-integration	0	Desktop platform memory and filesystem providers
deki-esp32-integration	2	ESP32 memory, filesystem, serial, and SD card providers
deki-fsm	1	Visual state machines with per-state action stacks and event-wired transitions
deki-gpio	1	Digital pins: drive, read, and count a pin's pulses by interrupt, plus a boot step that drives a pin. The platform package supplies the backend
deki-gps	2	GPS peripheral interface and NMEA-over-UART backend
deki-http	2	HTTP client facade with WinHTTP and curl backends
deki-i2c	1	I²C bus peripheral interface with an editor-configurable bus component
deki-i2s	0	I²S audio bus peripheral interface
deki-imu	1	Accelerometer + gyroscope peripheral interface with LSM6DS3 backend (hardware pedometer)
deki-input	3	Input handling and collision detection
deki-json	0	JSON parsing and serialization backed by cJSON
deki-lora	1	LoRa radio: an SX1262 driver with a duty-cycle limit, sending and receiving packets
deki-lovyangfx-integration	2	LovyanGFX display and touch panel integration
deki-nodegraph	0	Generic node graph editor: canvas view, domains, undo, and node registration
deki-particles	1	Modular particle emitter (gravity, drag, velocity, lifetime modifiers)
deki-rendering	2	Core rendering system with camera and renderer components
deki-rtc	2	Real-time clock peripheral interface and DS3231 (I²C) backend
deki-sdcard	1	SD card interface: mount, card state, capacity, and filesystem access
deki-sdl3-integration	2	SDL3 display, input, and filesystem integration
deki-tactility-integration	2	Runs a Deki game as a Tactility app. Builds and installs into the Tactility simulator; the on-device build is not written yet
deki-tiledmapeditor-integration	3	Loads and renders maps authored in Tiled (.tmj) with chunk streaming
deki-tween	1	Animation tweening with 30+ easing functions
deki-uart	0	UART serial peripheral interface
deki-wifi	0	WiFi interface: connect, disconnect, state, and access point scanning
