+ * @brief       Driver for displays with a ST77xx display controller
+ *
+ * The ST77xx display controller driver is a driver for small RGB displays
+ * using a ST77xx display controller. The driver supports ST7735, ST7789 and
+ * ST7796. The support of the respective controller is enabled by the
+ * corresponding module `st7735`, `st7789` or `st7796`. The ST77xx controller
+ * used by a display must be specified in the board definition in parameter
+ * @ref lcd_params_t::cntrl or as macro @ref ST77XX_PARAM_CNTRL if the
+ * default parameter set @ref ST77XX_PARAMS is used.
+ *
+ * The driver uses the SPI serial interface to communicate with the display
+ * controller.
+ *
+ * The device requires colors to be send in big endian RGB-565 format. The
+ * @ref CONFIG_LCD_LE_MODE compile time option can switch this, but only use this
+ * when strictly necessary. This option will slow down the driver as it
+ * certainly can't use DMA anymore, every short has to be converted before
+ * transfer.
