    Hi ppl,

    I like to figure out the TFT interface protocol that I am giving below from a site that I found (http://www.electricstuff.co.uk/ipodlcd.html) I tried contacting the site admin but, no luck. I need to learn the protocol to substitute the LCD for another smaller size. Here is the pin outs, as figured by the original author:

    Pin Function
    1 Not Used
    2 3.1V Supply
    3 1.8V Presumably I/O supply. All I/Os run at 1.8v levels
    4 0V
    5 /Reset.
    6 /CS Chip select
    7 /WR write strobe
    8 RS Selects command/data register ( called CD in some datasheets)
    9 /RD read strobe
    Data bus Colour
    10 D0 Blue 0
    11 D1 Blue 1
    12 D2 Blue 2
    13 D3 Blue 3
    14 D4 Blue 4
    15 D5 Green 0
    16 D6 Green 1
    17 D7 Green 2
    18 0V
    19 D8 Green 3
    20 D9 Green 4
    21 D10 Green 5
    22 D11 Red 0
    23 D12 Red 1
    24 D13 Red 2
    25 D14 Red 3
    26 D15 Red 4
    27 0V
    28 Vsync out. Goes high for 84.5us at frame rate of 47Hz
    29 0V
    30 Backlight -
    31 Backlight + Vf is 13.7V ( 4 white LEDs in series)
    32 Not used

    Can anyone help?

    Thanks.
