About emWin

emWin, the embedded GUI solution, is compatible with single-task and multitask environments with a proprietary operating system or with any commercial RTOS such as embOS. The GUI is shipped as "C" source code. emWin can be adapted to any size, either physical or virtual display, not dependent of the display controller and target CPU. Making it a professional GUI for the embedded market, usable for multiple different scenarios.

Reliability

SEGGERs GUI emWin is deployed in a huge number of mass market devices.
It is considered the industry standard for user interface and graphic software in the embedded industry.

 

Efficiency

emWin is a high-performance graphics package that has been optimized for minimum memory consumption in both, RAM and ROM, as well as high speed, and versatility. Making it a state-of-the-art solution for GUIs.

Availability

emWin supports virtually any display and display controller. The GUI can use any type of display controller. If a controller is not yet supported, please contact us to create a working solution for your needs.

Output Quality

The embedded GUI solution emWin provides high quality graphic functions that create the highest level of detail as required by the application.

 

 

Getting Started

Adding emWin to the Target Program

You basically have a choice between including only the source files that you are actually going to use in your project, which will then be compiled and linked, or creating a library and linking the library file. If your tool chain supports "smart" linking (linking in only the modules that are referenced and not those that are not referenced), there is no real need to create a library at all, since only the functions and data structures which are required, will be linked. If your tool chain does not support "smart" linking, a library makes sense, because otherwise everything will be linked and the program size will be excessively large. For some CPUs we have example projects available to help you get started.

Generally speaking, you need to include the core C files of emWin, the display driver, all font files you plan to use, and any optional modules you have ordered with emWin.

Configuration

Before emWin can be used on a target system, the software needs to be configured. Configuring means, modifying the configuration files which usually reside in the configuration sub directory. We try to keep the configuration as simple as possible, but there are some configuration routines which need to be modified in order for the system to work properly.

The following items need to be configured: •

  • Memory area to be used by emWin •
  • Display driver to be used for drawing operations •
  • Color conversion routines to be used •
  • Display controller initialization •
  • Hardware acceleration

Writing Applications

emWin comes with an extensive collection of samples and tutorials which could be easily used as starting point. To get something on the display the typical 'Hello World' application looks as follows:

MainTask(void) {
  GUI_Init(); 
  GUI_DispString("Hello World!"); 
  while (1) { 
    GUI_Delay(5); 
  } 
}
