    hi everybody

    first, sorry for my bad english, i'm french !

    i use a LCD with T6963C controller and a PIC CPU.
    all work fine. i can draw a full screen ( 240*128 ) with BMP file in less
    than 1.5 seconde .. cool ! ;-)

    but i have some trouble with the SCREEN_PEEK command. i want to use it to,
    for example, reverse ( video ) a full screen.
    this work fine .. i obtain a right video inversion ... BUT to do the full
    screen reverse, it take about 35 secondes !!! ...

    please, if anybody use this command .. can he send me his routine ( asm,
    basic, C .... ) ?

    what i do :

    for index = ....
    SCREEN_PEEK command
    READ data
    convert DATA
    WRITE data
    next

    what is wrong ???? ( i check of course, all the status flag needed .. )

    thank's, please help !

  2. Are you sure you are not attempting to access RAM outside the graphic
    area?
