Detailed Description
Driver for ili941 display.
The ILI9341 is a generic display driver for small RGB displays. The driver implemented here operates over SPI to communicate with the device.
The device requires colors to be send in big endian RGB-565 format. The ILI9341_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.
