Description
Advanced GUI (Graphic User Interface) LCD driver library for Graphic S1D13700/ SED1335, RA8835 / S1D13305 LCD modules.
Be up and running with your graphic LCD module application using advanced
features like symbol and icon display, soft-font text and line drawing,
in just a few hours. Save weeks of hard programming.
The powerful and flexible function interface provides the basic drawing features
which make it simple for a programmer to create screen data fields, pull-down menus, pop-up menus,
progress bars, etc. The library facilitates the creation of any GUI "style" and "look"
most suitable for a particular target application area.
The library supports soft fonts for both mono-space and proportional graphic text.
All font handling is done transparently by the library. The programmer just
selects the wanted font.
Font support for 8-bit character sets, extended 16-bit character sets, national
ASCII character sets, ISO-IEC 10646, and UNICODE.
Supports dynamic codepage look-up and segmented fonts. This makes it possible to reduce a
large font so it only contains those character symbols used by the application, while
the C text strings remain unchanged. Ideal for memory-constrained embedded systems.
Multiple viewports with wrap and scroll. This makes it easy to reserve areas on the
display for icons and to prevent overwriting. Within a viewport text can be output
as left or right aligned, cut at the edges, or centered horizontally and vertically.
Each viewport can have its own font and codepage. Text scrolling can be done individually
for each viewport.
Start programming and test before your hardware is ready. The PC-mode simulator for Windows
supplied with the library allows you to program and test embedded S1D13700/ SED1335, RA8835 / S1D13305 LCD
applications, using common PC compilers from Borland and Microsoft. Your
LCD application source code will look the same in PC mode and target mode.
The library is written entirely in C using a standardized function syntax for basic I/O read and write. The
library is supplied as C source code and can therefore be compiled with standard conforming
C, C++, or EC++ compilers for all common embedded processor families. For instance: 80x51,
80x86, 80C167, 68HC11, 68HC16, 683xx, H8/300, H8/300H, H8S, M16, PIC17, PIC18, PIC24, PIC32, dsPIC, AVR, AT9x, ARM, etc.
The library functions are well modularized. Advanced features can be
added successively to the basic S1D13700/ SED1335, RA8835 / S1D13305 LCD driver system. For instance: graphic
support, viewport support, symbol and icon support and soft-font text
support. This makes it easy to adapt the library to the requirements of your
application, and optimize ROM and RAM memory consumption.
The same LCD driver function interface exists for different LCD
controller types. This makes it easier to create portable and
reusable application software. Changing to LCD modules using
another LCD controller type is now a simple task.

Go to download of LCD driver and PC-simulator demos
The demo uses the LCD PC-simulator supplied with the library package
and demonstrates many of the features which become easily available when
using the S1D13700 / SED1335 Graphic LCD driver package. The simulator uses the same
pixel resolution as you will have with the real display hardware.
See also the Graphic
LCD Icon Editor development tool
This tool makes it particularly easy for you to create your
own graphic logo and symbols. With the LCD Icon Editor you can also create
new soft fonts for the Graphic LCD library or import and convert standard
soft fonts used on the PC.
See also the Extended Graphic
Font library
Source library with a large number of ready made fonts. Support for Unicode,
Iso8859 or Dos code-pages.
Contains characters from many languages, for instance: all latin characters,
Greek, Cyril, Armenian, Hebrew, Arabic, Thai, Georgian, Hangul, Ethiopic,
Cherokee, Runic, etc.
Can be used directly with the S1D13700 / SED1335 LCD driver library.

See also the Extended Asian Graphic
Font library
Source library with large Asian fonts.
Contains character symbols from many languages, for instance: Simplified Chinese,
Traditional Chinese, Japanese, Korean, CJK unified ideographs, Katakana, Hangul,
all latin characters, Greek, Cyrillic, etc.
Can be used directly with the S1D13700 / SED1335 LCD driver library.
See also the
IOTester development kit
IOTester is the easiest way a C/C++ program developer from the PC can get direct access
to controlling LCD displays and other peripheral I/O hardware in an embedded system.
With this tool embedded GUI interfaces can be tested on the PC, using common compiler tools,
while all I/O operations are done on the real GUI hardware (for example write to LCD display, poll of keyboard, etc). This is the
most convenient way to test the "look and feel" of a new GUI interface.
Can be used directly with the S1D13700 / SED1335 LCD driver library.
