SEGGER Microcontroller
SEGGER Microcontroller develops and distributes software development tools and ANSI "C" software components (middleware) for embedded systems in several industries, such as telecom, medical technology, consumer electronics, the automotive industry, and industrial automation. SEGGER´s intention is to cut software development time for embedded applications by offering compact, flexible and easy to use middleware allowing developers to concentrate on their applications.

Our most popular solutions consist of emWin, a universal graphic software package for embedded applications, and embOS, a small yet efficient real-time kernel. emWin, written entirely in ANSI "C", can easily be used on any CPU and most any display. It is complemented by the available PC tools: Bitmap Converter, Font Converter, Simulator and Viewer. embOS supports most 8/16/32-bit CPUs. Its small memory footprint makes it suitable for single-chip applications. embOS comes with a viewer that allows looking into the system from a development PC (this viewer includes profiling).

Apart from our main focus on software tools, SEGGER has also developed and produces a programming tool for flash microcontrollers and a USB to JTAG emulator to assist in development, debugging and production. This USB to JTAG emulator, known as j-link, has fastly become the industry standard.
