Detailed Description

Set of low level procedure to manage QVGA display. Below a typical init example:

        Set_SPI(SPI_PP);                        // Select SPI expansion port channel
        Set_ExpansionPort(0xF0);        // Init expansion port
        Set_TFTlightPower(true);        // Turn display power
        Set_TFTlight(15);                       // Set maximu backligth
        Set_SPI(SPI_TFT);                       // Select SPI display channel
        Set_TFTinit();                          // Init display
