Graphical software library from SEGGER for EFM32 MCUs from Energy Micro

EmWin high-quality graphical software library from SEGGER is available to configure graphical user interfaces for products ranging from portable health and fitness monitors to smart accessories designed using EFM32 Gecko MCUs from Energy Micro.

By integrating emWin with Energy Micro's Simplicity Studio design environment, designers are supported to make immediate use on-chip TFT and LCD controller that is a feature of the EFM32 Gecko series of MCUs.

"Incorporating a low-power display controller on-chip gives designers unrivalled flexibility in HMI and display options for low-energy applications, especially for users of our large memory Giant and Leopard Gecko processors," said Andreas Koller, VP Sales and Marketing at Energy Micro. "Working closely with SEGGER provides first-class software support for these features, allowing users to produce high-quality graphics results quickly and without license agreement concerns."

emWin supports unique font converter and unicode language support, color management and graphical layering. Compatible with single-task and multitask environments, proprietary operating systems or with any commercial RTOS, emWin can adapt to displays of any physical or virtual size.

The direct drive TFT controller within the EFM32 Giant and Leopard Gecko MCUs allows full-rate (60fps QVGA/30fps HVGA) video output from external memory while the CPU remains in an energy-saving deep sleep mode. It supports up to 16-bit color and displays without an internal frame buffer, and offers functions such as scrolling, alpha blending and bit masking. EFM32 microcontrollers with an LCD driver can directly drive segment displays with a current consumption of just a few hundred nanoamps.
