Default params.

Note

The default parameter set defined here can only be used if a single ST77xx display and only one interface mode is used. If multiple ST77xx displays are used or if multiple interface modes are enabled by the modules lcd_spi, lcd_parallel and lcd_parallel_16bit, a user defined parameter set ST77XX_PARAMS has to be defined. In the latter case lcd_params_t::spi must then be set to SPI_UNDEF for displays with MCU 8080 8-/16-bit parallel interfaces.
