Renesas Electronics has extended its license for emWin, Segger’s graphical user interface (GUI) library, across its entire family of RX microcontrollers.

The license enables RX customers to design, develop, and produce GUI-driven applications without extra cost on any RX microcontroller, which are based on a Renesas proprietary CPU core. The deal extends an agreement from 2017.

For the increasing number of embedded devices offering graphical user interfaces, the emWin graphics library has been optimized for minimum memory consumption in both RAM and ROM, as well as for high speed and versatility. It supports both superloop-style and multi-threaded applications and can be used on any RTOS. emWin can support one or more displays, each with differing geometries and color depths, can support physical or virtual displays, and is easily retargeted for different display controllers and microcontroller architectures.

User interface (UI) creation software called AppWizard includes tools to build complete and ready-to-run emWin applications without writing code.

Most of emWin’s core features such as widgets, animations, language management and motion support can easily be applied to swiftly create applications and no knowledge of the C language is required. Because the GUI can be prototyped on the PC with pixel-perfect rendering, development can be started even before the target hardware is available.

“Segger’s emWin with AppWizard is used by developers worldwide to deliver state-of-the-art GUIs for consumer devices and industrial equipment,” said Roger Wendelken, Senior Vice President in the IoT and Infrastructure Business Unit at Renesas. “We’re pleased to offer our RX customers this outstanding package.”
