Stellaris Graphics Library provides two levels of support for rendering graphical elements In the lowest level basic drawing primitives are provided such as lines circles rectangles and text rendering Each primitive supports clipping to a single clipping rectangle allowing only a portion of the display to be affected by the drawing primitives Building upon the drawing primitives is a widget set which combines the drawing of graphical elements with reactions to pointer events in this case presses on the touch screen The widget set includes push buttons check boxes radio buttons sliders listboxes and drawing canvases By using the widget set complex interactive graphical displays can be constructed quickly A set of drivers for the on board peripherals is also provided This includes a driver for the touch screen the audio codec the USB CAN and the microSD card Ethernet is supported by TCP IP stacks and example applications all within the StellarisWare libraries The IDM SBC is also supplied with a set of example applications that utilize the Stellaris Peripheral Driver Library and the Stellaris Graphics Library along with the board specific drivers for the on board peripherals These applications demonstrate the capabilities of the IDM SBC and provide a starting point for the development of the final application for use on the IDM SBC All example applications are integrated with the Stellaris boot loader to allow automatic fir
