Color Display Driver Circuit and Driver Development for Embedded System Based on ARM Microcontroller
Harini H M, Ravikumar M N
Abstract: Displays generally handle data input as character maps or bitmaps. In character-mapping mode, a display has a pre-allocated amount of pixel space for each character. In bitmap mode, it receives an exact representation of the screen image that is to be projected in the form of a sequence of bits that describe the color values for specific x and y coordinates starting from a given location on the screen. Displays that handle bitmaps are also known as all-points addressable displays. A display driver supports a particular family of display controllers and all displays which are connected to one or more of these controllers [2]. The drivers can be configured by modifying their configuration files whereas the driver itself does not need to be modified. The configuration files contain all required information for the driver including how the hardware is accessed and how the controllers are connected to the display. EmWin handles all access to the display.
