ddi_display_controller_lds514.c

LCD驱动源代码 应用于手机的话,需要改写,找了好久,网上下的,将就一下了,参考参考,自己动手改一下吧.有在MTK平台上改成功的,放上来给大家参考一下啊

//!
//! The display driver is built with a default width and height for each
//! controller.  Most controllers support displays of varying screen
//! dimensions.  In order to support all possible dimensions without rebuilding
//! the display libraries, this function can set the dimensions of the display
//! to match the actual display in use.  This function only needs to be called
//! once to set the dimensions for the currently set screen orientation.  If the 
//! display is rotated after the dimensions are set, then the dimensions will
//! be adjusted accordingly in the display driver.  There is no need to reset
//! the dimensions after rotating the display.
//!
//! \retval SUCCESS No error
//!
//! \retval ERROR_DDI_DISPLAY_CONTROLLER_RESOLUTION The specified resolution is
//!         not supported by the controller
