Core Capabilities

Precision Drawing Tools

> 1-Bit Graphics Engine & Editor

Everything you need to design pixel-perfect monochrome graphics without the bloat.

  • ■ Comprehensive drawing and editing tools.
  • ■ Advanced selection, transformation, and canvas operations.
  • ■ Clean, distraction-free interface focused on pixel manipulation.
Direct Source Code Sync

> Sprite Extraction

Turn mystery C-arrays back into visual art. No math, no spreadsheets—just point Hexprite at your `.h` file and watch every embedded sprite reconstruct instantly.

  • ■ Scans entire .c, .h, or .py files to extract embedded sprites.
  • ■ Automatically detects variable names, dimensions, and formats.
  • ■ Provides mini visual thumbnails for inspection before importing.
Embedded Typography

> Direct Source File Syncing

Stop juggling web converters, formatting templates, and tedious copy-pasting. Hexprite links directly to your project’s .c, .h, or .py files.

  • ■ Saves in Hexprite instantly update your source code in VS Code, CLion, or PlatformIO.
  • ■ Manual source code edits sync automatically back to Hexprite.
  • ■ Easily restore files to their original states if needed.
Live Hardware Streaming

> Live Hardware Preview

Connect your Arduino, ESP32, STM32, or Raspberry Pi Pico via USB and watch your sprites come to life on physical OLED/e-Paper displays while you draw.

  • ■ Every pencil stroke and selection reflects instantly on your hardware.
  • ■ Preview multi-frame animations at full frame rates over high-speed serial.
  • ■ Temporarily takes over the display without overwriting your firmware.
Sprite Animation

> Embedded Typography

Go beyond sprites with a dedicated, professional embedded bitmap font editor built from the ground up for microcontroller displays.

  • ■ Design custom monospace and proportional bitmap fonts pixel-by-pixel.
  • ■ Export to Adafruit GFX, u8g2, and LVGL with tight auto-cropping.
  • ■ Convert TrueType, BMFont, or sprite sheets into editable monochrome pixel fonts.
Advanced Dithering

> Animation Studio

Bring 1-bit art to life. Design, onion-skin, preview, and export frame-by-frame animations directly into embedded C-arrays, animated GIFs, and Flipper Zero packages.

  • ■ Multi-frame timeline with onion skinning and batch frame operations.
  • ■ One-click export to microcontroller-ready C-arrays and lookup tables.
  • ■ Export to animated GIFs or native Flipper Zero animation bundles.
Native Flipper Zero Support

> Advanced Dithering

Turn photos and graphics into striking monochrome art for your OLED, LCD, or e-Paper display.

  • ■ Convert full-color photos into 1-bit art using 6 mathematical algorithms.
  • ■ Smart edge locking ensures silhouettes stay sharp and readable.
  • ■ Draw, shade, and fill with interactive dither patterns.
Flipper Zero Integration

> Flipper Zero Integration

No Python scripts. No manual `meta.txt` editing. Hexprite is purpose-built to read, animate, and export Flipper Zero formats natively.

  • ■ Open and save native `.bm` bitmap icons and animations directly.
  • ■ Encodes frames with native compression for minimal Flash footprint.
  • ■ Export ready-to-blit assets for custom C/C++ Flipper applications.

Development Roadmap

Where Hexprite is today, and where it's heading next. Built in the open for embedded software engineers and makers.

⚡ IN DEVELOPMENT PHASE 01

1-Bit & Typography

Core Engine & v1.0 Foundation

  • ■ Strict 1-Bit Engine: Pixel art, layers, and 6+ dithering algorithms for OLED & e-Paper.
  • ■ Embedded Font Studio: Glyph editor with TTF/BMFont import and Adafruit/u8g2/LVGL export.
  • ■ Live Hardware Preview: Real-time USB/Serial streaming with one-click baud auto-detect.
  • ■ Direct Code Generation: C/C++ arrays for Adafruit GFX, u8g2, LiquidCrystal, and MicroPython.
  • ■ Multi-Color E-Paper & Tilesets: 2-bit planes (B/W/Red) and tilemap studio for retro games.
Target: v0.3.x Beta → v1.0 Stable
○ PLANNED PHASE 02

Motion & Tooling

Motion Graphics & Pipeline

  • ■ Keyframe Timeline & Curves: Animate transform properties with visual Bezier easing curves.
  • ■ Dual-Mode Tweening: Pre-baked frame sequences for 8-bit MCUs + C runtime for 32-bit chips.
  • ■ Headless Build CLI: Compile .hexp and .hexfont assets in PlatformIO & CMake CI/CD.
  • ■ IDE Integration: VS Code & PlatformIO context menus to open C-arrays directly in Hexprite.
  • ■ Cross-Platform Port: Linux and macOS desktop support via modern cross-platform UI.
Target: v1.1.0 → v1.5.0
○ PLANNED PHASE 03

Color Displays (RGB565)

TFT & Full-Color Era

  • ■ Popular TFT Display Support: Native profiles for ST7789, ILI9341, GC9A01 round dials, and TFTs.
  • ■ Multi-Depth Color Canvas: Seamless switching between 1-bit, 2/4-bit grayscale, and 16-bit color.
  • ■ Hardware Palettes: 16 & 256-color indexed modes with hardware-constrained quantization.
  • ■ LVGL True-Color Export: Direct code generation for LVGL v8/v9 color UI components.
  • ■ SPI Flash Asset Packaging: Pack frames into binary bundles for external Flash (W25Q) & SD cards.
Target: v2.0.0 (Future Release)
