Cortex-M3 gets a GUI
PrismX represents a ThreadX RTOS-integrated port of Blue Water Embedded’s Prism technology that is marketed and supported by Express Logic. Incorporating GUI development tools and libraries, PrismX is comprised of the PrismX Runtime Framework, a full-featured GUI toolkit, PrismX Micro, a GUI toolkit for monochrome to 8-bit colour-depth targets, and PrismX Insight, a desktop GUI design and resource editing tool.
Integrated to take advantage of STM32’s capabilities, PrismX delivers a high-performance graphical drawing library and a GUI widget set for this platform. Demonstrations of the PrismX GUI design package on an STM32F10C system are available online at www.rtos.com/downloads/threadx_demo and can be viewed live March 1-3, in the Express Logic booth (Hall 11- Stand 124) at Embedded World 2011, in Nuremberg, Germany.
The demonstration involves a simple media player application using many PrismX features including gradient-filled 3D buttons, anti-aliased fonts, screen transition animations, and scrolling lists.
The STM32’s limited onboard RAM requires that PrismX execute without a traditional graphics frame buffer. To work around this, all drawing operations cause immediate updates to external GRAM memory of the LCD.
The PrismX development platform, PrismX Insight, offers a large range of data output formats such as C++ source code, XML screen description files, and binary resource files, enabling developers to tailor output to the requirements and capabilities of target systems. PrismX works with Express Logic’s ThreadX RTOS to provide a graphics capability for embedded applications requiring graphical displays and user interfaces. The PrismX GUI package includes the PrismX Core Library, the PrismX Insight Development Tool, all documentation and a screen driver. Full support includes integration files for the ThreadX RTOS, and project files and demo code provided for IAR’s EWARM tool suite.
