Graphic Color Dot Matrix Driver Library for Grey-level LCD display modules

C source display driver library for the UC1611 family of display controllers

GUI Grey-level display driver library
Color GUI library - See common high-level interface overview

The display driver library package is optimized for use in small embedded systems using LCD and OLED display modules with display controller chip types in the Grey UC1611 display controller family:

UC1538 UC1610 UC1611 UC1611S UC1617S UC1638 UC1658 ST7511 ST7528 ST7571 ST7586 ST75256 SSD0323 SSD1320 SSD1322 SSD1325 SSD1326 SSD1327 SSD1328 SSD1329 and equivalents.

The Grey-Level 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

  • Display controller family features
    • Supports Grey-level display controllers for LCD display screen types
    • All dot matrix display screen sizes supported by the display controller family. For instance 128x128, 128x132, 240x160, etc.
    • Support for 1, 2, or 4 bits per pixel Grey-level in hardware.
    • Portrait and landscape orientation: 0, 90, 180, 270-degree display rotation. (ST7528 only 0,180)
    • Support for 8-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.
    • Touch Screen support
  • 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.
    • Comprehensive easy-to-read manual with examples
    • No run-time licenses.
    • Color LCD display controller PC-simulator included for debugging of embedded GUI applications with standard PC compilers.
  • 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)
    • Transparent symbol pixels. Symbols can use any geometric form.
    • Free user definition of special symbols.
  • 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
  • Fonts and Text support
    • Character and text string functions.
    • Soft-font support
    • Support for extended codepage 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.
    • Mono-space and Proportional fonts.
    • Support for anti-aliased fonts
    • Support for transparent text
    • Fonts can be stored as two-color (B&W) symbols to optimize memory consumption.
  • Viewports and GUI Styles
    • Viewports with scroll, auto-wrap and auto-alignment.
    • Tabs and column alignment support.
    • Selectable foreground and background colors with both text and graphics.
    • Selectable fonts and alignemnt styles.
    • Fast block-swapping of foreground and background colors. Ideal for block cursors in menus and progress bars.
    • Comprensive, easy-to-use function interface. The powerful feature set enable creation of any GUI style.
    • Use relative coordinate set. Create adaptable layouts. Design your owen reusable GUI functions.
  • Low processor memory consumption
    • Library is designed for use with embedded processors. Small memory footprint. Heap memory not required.
    • Can operate directly on internal video buffer in the display controller chip. No need for a graphic video buffer in processor RAM.
    • Selectable use of direct video memory I/O, or fast delayed update via RAM buffer.
    • Suppport for 1 bit per pixel buffered mode (compressed B&W buffer mode)
    • 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.
