The Graphic LCD Controller (GraphicLCDCtrl) component provides the interface to an LCD panel that has an LCD driver, but not an LCD controller. This type of panel does not include a frame buffer. The frame buffer must be provided externally.
This component also interfaces to an externally provided frame buffer implemented using a 16-bit wide async SRAM device.
This Component is designed to work with the SEGGER emWin graphics library. This library provides a full-featured set of graphics functions for drawing and rendering text and images. emWin graphics library available for PSoC™ 3, PSoC™ 4 and PSoC™ 5LP devices.
