Beaglebone in LIDD Mode

Kilohercas

Does any one know how to program LCD with SSD1963 controller in LIDD mode?

Since bit banging is slow, even at 1,2GHz overclock (below 10MHz)

But how to do that in raw C in IAR or CCStudio , not some Linux or other nonsense

    Hi Linas,

     

    I'm not sure a LCD with SSD1963 is designed for the LCD controller built-in to the TI chip. Isn't the SSD... type chip used when you want to interface to an address and data bus and write graphics instructions with no need for constant refresh? Whereas the LCD controller on the Beaglebone is intended for refreshing a TFT display without this type of interfacing controller.

    I could be very wrong though.

    LCD controller can be interfaced to i80 bus, and that mode is called LIDD

     

    LCD D0-D15: 16 bits of data/address lines
    LCD_VSYNC     -> RS (also called Command/Data or CD or Address/Data; NOT reset)
    LCD_HSYNC     -> Write-bar
    LCD_PCLK     -> Read-bar
    LCD_AC_ENB_CS     -> Chip Select 0
    LCD_MCLK     -> Chip Select 1

    but have no idea how to program that in C
