µC/GUI Graphical User Interface
Sourcecode
µC/GUI is delivered as ANSI-C source code. The source code is characterized by its consistency and efficiency. All services provided by µC/GUI start with a prefix related to the module that it belongs to (e.g. "GUI" = µC/GUI Core, "WM" = Window Manager). This makes it easier to differentiate the functions of GUIs with respect to their application.
Portability
µC/GUI can be used with all CPUs and does not require any C++ compiler, because µC/GUI is written 100% in ANSI-C. µC/GUI can run with 8 to 32-bit processors; for performance reasons, having at least 16-bit CPUs is recommended.
User manual
The sourcecode of µC/GUI is structured and well documented. In addition to the excellent software quality, you are given a manual with over 800 pages describing the API and the tools.
Expansion options
The following modules can be selected depending on memory availability or requirements.
Memory drivers: used to prevent flickering during image compilation with overlapping elements.
Window manager: allows you to create and handle different windows of any size.
Widget: widgets are windows with certain properties: buttons, radio buttons, scroll bars, list boxes and more. In the Windows world, widgets are also called "controls".
Dialogs: dialogs are windows that are displayed at the user's request. They can contain widgets, request information from the user through various selection options, or it may simply take the form of a message box with an "OK" button.
Touch screen: touch screen support contains a low-level driver that takes over the input signal (two 8-bit ports or respectively two A/D converter channels), the debouncing and the calibration of the display.
Antialiasing: smoothes curves and diagonal lines are achieved by "blending" the background color with the color of the foreground.
Multiple displays: windows can be positioned in different layers or displays. Drawing functions can be utilized on every layer or display. Multiple layers and displays are handled the same (with the same API functions). The µC/GUI view tool allows you to view each layer (or display) during the tests, and in the case of multiple layers, to visualize the current issue status.
LCD drivers: drivers are available for most of the conventional LCD controllers. Ask about your display or LCD controller type.
PC tools
µC/GUI contains many development tools that support your GUI development.
µC/GUI Bitmap Converter: The Bitmap Converter is a tool to convert bitmaps into a C file. Some useful functions can be performed with the bitmap converter: horizontal and vertical reflecting and rotating of the image and inverting of the bitmap indices or colors.
µC/GUI Font Converter: with the Font Converter and Editor, true-type fonts can be converted into a C file. In this way, the font can be used with µC/GUI. µC/GUI can handle Unicode characters.
Simulator: µC/GUI contains a simulation environment for Windows. The entire user interface can be developed and tested on the PC. The simulation environment uses the same API functions as the µC/GUI library on the target system. In this way, a complete development environment is available before the hardware is finished. Creating screenshots can be done in a moment's time and is helpful for the documentation.
Memory requirements
The memory requirements depend on which parts of µC/GUI are used. The following requirements are possible as standard values for typical systems:
| RAM | Stack | ROM | |
| Small systems (no window manager) | 100 Bytes | 500 Bytes | 10-25 KB (depending on the used functionality) |
| Large systems (with window manager and widgets) | 2-6 KByte | 1200 Byte | 30-60 KB (depending on the used functionality) |
