    Поддерживаемая глубина цвета - 16 бит.

    Драйвер поддерживает 8-ми и 16-ти битный параллельный интерфейс, а также SPI для 3-х линий управления. По умолчанию настроен на параллельный 8-ми битовый интерфейс.

To be able to use this driver the following macro definition needs to be added to the configuration file 

Для использования данного драйвера необходимо добавить макроопределение в файл LCDConf.h:

#define LCD_USE_COMPACT_COLOR_16

    После этого макроопределения в конфигурационном файле LCDConf_CompactColor_16.h добавляется строка:

GUI_DEVICE_CreateAndLink(GUIDRV_COMPACT_COLOR_16, GUICC_565, 0, 0);

    Драйвер может использоваться с дисплейным кешем в RAM или без него. Общее количество памяти для кэша

LCD_XSIZE * LCD_YSIZE * 2 bytes    (для дисплеев 320Х240Х2=153600)

        Конфигурационные макроопределения

    To select the desired controller the macro LCD_CONTROLLER should be used in the configuration file LCDConf_CompactColor_16.h. The following table shows the values to be used to select the appropriate controller:

    В файле  LCDConf_CompactColor_16.h задается макроопределение LCD_CONTROLLER определяющее тип контроллера

    Конфигурация дисплея задается макроопределениями

LCD_MIRROR_X Activate to mirror X-axis.
LCD_MIRROR_Y Activate to mirror Y-axis.
LCD_SWAP_XY Activate to swap X- and Y-axis.

    Конфигурация оборудования

LCD_NUM_DUMMY_READS	Number of required dummy reads if a read operation should be executed. The default value is 2. If using a serial interface the display controllers HD66766 and HD66772 need 5 dummy reads. Sharp LR38825 needs 3 dummy reads with a 8-bit bus.
LCD_REG01	This macro is only required if a Himax HX8312A is used. Unfortunately the register 0x01 (Control register 1) contains orientation specific settings as well as common settings. So this macro should contain the contents of this register.
LCD_SERIAL_ID	With a serial 3 wire interface this macro defines the ID signal of the device ID code. It should be 0 (default) or 1. Please note: This macro is only used with the 3 wire protocol for Hitachi HD66772, Samsung S6D0117, Himax HX8301 and Ilitek ILI9220.
LCD_USE_SERIAL_3PIN	This configuration macro has been implemented to support the 3 wire serial interface of the following controllers: Hitachi HD66772, Samsung S6D0117, Himax HX8301, Ilitek ILI9220. Should be set to 1 if the 3 wire serial interface is used. Default is 0. Please note: Do not use this macro with other display controllers!
LCD_USE_PARALLEL_16	Should be set to 1 if the 16 bit parallel interface is used. Default is 0.
LCD_WRITE_BUFFER_SIZE	Defines the size of the write buffer. Using a write buffer increases the performance of the driver. If multiple pixels should be written with the same color, the driver first fills the buffer and then writes the contents of the buffer with one execution of the macro LCD_WRITEM_A1, instead of multiple macro executions. The default buffer size is 500 bytes.
LCD_WRITE_A0	Write a byte to display controller with RS-line low.
LCD_WRITE_A1	Write a byte to display controller with RS-line high.
LCD_READM_A1	Read multiple bytes (8 bit parallel interface) or multiple words (16 bit parallel interface) from display controller with RS-line high.
LCD_WRITEM_A1	Write multiple bytes (8 bit parallel interface) or multiple words (16 bit parallel interface) to display controller with RS-line high.
LCD_WRITEM_A0	Write multiple bytes (8 bit parallel interface) or multiple words (16 bit parallel interface) to display controller with RS-line low.
