Graphic Color Dot Matrix display driver library

Graphic GUI display driver library for the S6D0129 family of LCD / TFT / OLED display controllers.
The C source library provides a comprehensive and easy to use feature set for output of text, fonts and graphic images in embedded systems. Save weeks of programming. These RGB display controller types are supported by the S6D0129 family library package:

S6D0129 family RGB GUI display driver library

The RGB display driver library implements the powerful and flexible high-level GUI application interface functions and features set common for RAMTEX Color Dot Matrix library packages.

Feature list

  • Graphic display module support
    • Supports RGB display controllers for LCD / TFT / OLED display screen types
    • All dot matrix display screen sizes supported by the display controller. For instance, 640x480, 240x320, 320x240, 128x128, etc.
    • Support for 16, 18, 24-bits per pixel RGB in hardware frame buffer.
    • Can operate directly on internal video buffer in the display controller chip. No needs for a graphic video buffer in processor RAM.
    • Portrait and landscape orientation: 0, 90, 180, 270-degree display rotation.
    • Touch Screen support
  • Graphic drawing
    • Graphic line drawing and pixel setting.
    • Graphic Rectangle and Block drawing.
    • Graphic buffer Cut and Paste.
    • Transparent symbol pixels. Symbols can use any geometric form.
    • Rotation of text and graphic symbols
  • Graphic symbols
    • One common function interface supports multiple symbol pixel data formats:
        -   1 bit per pixel (B&W or two-color)
        -   8, 4, 2 bits per pixel grey-level (anti-aliased)
        -   4, 2 bits per pixel RGB palette
        -   24, 16, 8 bits per pixel RGB
        -   32 bits per pixel ARGB (semi-transparent symbols)
    • Transparent symbol pixels. Symbols can use any geometric form.
    • Free user definition of special symbols.
  • Fonts and Text support
    • Character and text string functions.
    • Soft-font support
    • Mono-space and Proportional fonts.
    • Support for international fonts and extended code page tables, ISO-IEC 10646, and UNICODE.
    • Support for extended character set handling. Multibyte character strings, wide-char strings.
    • Full UTF-8 string support, incl. conversion functions.
    • Support for anti-aliased fonts
    • Support for transparent text
    • Fonts can be stored as two-color (B&W) symbols to optimize memory consumption.
    • Full support for Virtual Fonts, icons, and pictures stored in external memory devices. An easy way to handle large fonts and graphic objects with minimum processor memory consumption.
    • Includes support for Virtual Files. Save text strings and application data together with fonts. Enable easy language update after product release.
  • Viewports and GUI Styles
    • Viewports with scroll, auto-wrap and auto-alignment.
    • Tabs and column alignment support.
    • Selectable fonts and alignment styles.
    • Selectable foreground and background colors with both text and graphics. Transperant write of anti-aliased text and symbols.
    • Fast block-swapping of foreground and background colors. Ideal for block cursors in menus and progress bars.
    • Flexible, easy-to-use function interface. The powerful feature set enable creation of any GUI style.
    • Create adaptable layouts. Design your own reuseable GUI functions.
    • Example library included.
  • Low processor memory consumption
    • Library is designed for use with embedded processors. Small memory footprint.
    • Selectable use of direct video memory I/O, or fast delayed update via RAM buffer.
    • Heap memory not required.
  • Display driver C source code
    • GUI display controller driver library provided as full C source code.
    • Standard conforming C source code. Can be used with embedded processors supported by a C, C++, or EC++ standard-conforming compiler.
    • Processor and OS independent driver code. Standardized I/O functions create driver source code portability.
    • Color LCD / TFT / OLED display controller PC-simulator included for debugging of embedded GUI applications with standard PC compilers.
    • Comprehensive easy-to-read manual with examples
    • No run-time licenses.
  • Display controller hardware
    • Support for 8-bit, 16-bit and 32-bit parallel bus modes and serial bus modes (e.g. SPI). All the display controllers use indexed bus addressing (only one address pin used). Small connector pin count.
    • Display controller types with built-in display screen driver (primarily COG types):
      S6D0129, HX8312, HX8325, HX8345, HX8346, HX8347, HX8352, HX8353, HX8367, ILI9340, ILI9341, ILI9163, ILI9320, ILI9325, ILI9328, ILI9331, ILI9335, ILI9221, ILI9222, ILI9225, LGDP4524, NT39122, OTM2201, OTM3225, R61505, R61506, R61509, R61580, S6B33BF, S6D0144, S6E63D6, SEPS525, SPFD54126, SPFD5408, SPFD5420, SSD1283, SSD1284, SSD1285, SSD1286, SSD1288, SSD2119, SSD1355, SSD1298, SSD1289, ST7628, ST7735, ST7773, ST7781, ST7787, ST7789, TL1771, UC1682, UC1697, UC1698
