Segger develops and distributes software development tools and ANSI C software components for embedded systems. Main products are : emWin, an universal graphics software (GUI) for embedded applications; embOS, a small real-time kernel; emFile, an embedded file system; USB stacks; and J-Link, the JTAG emulator for ARM cores. Segger cuts software development time for embedded applications by offering compact, flexible and easy-to-use middleware.
The emPower eval board provides a comprehensive set of SEGGER’s middleware products, accelerating the start of any embedded project. SEGGER’s embOS real-time operating system is at the heart of the evaluation. Furthermore, evaluation versions of the file system emFile, graphics library emWin, emUSB Host & Device, and TCP/IP stack embOS/IP (including web server demo) enable full use of the available emPower peripherals.
emPower also features a J-Link OB, an on-board version of SEGGER’s market-leading debug probe J-Link.
There are three expansion interfaces to easily connect additional modules. Each connector provides I2C, SPI, UART, GPIO/timer, analog input and power. A display adapter connector enables the connection of small TFT displays.
The emPower board is powered by USB only. Current consumption drawn strongly depends on the application and connected peripherals. Idle consumption is approx. 85 mA.Controller:
