    Default Re: 7 segment display

    Thank you for the help,
    the pause after the I2Cread was screwing me up badly.
    I get clear segments now.
    I now have a different issue !!
    Some of the segments not being used oare still being lit lighty !! I found that the dimm display on one display module was a pale mirror image of the display module next to it. I posted a picture to help understand what i'm talking about.
    Basically i have a 1 and 6 I can see (barely) on the 1 module all the segments of the 6 in the 1 module. I guess thats what is called ghosting..

    UPDATE: solved the problem by adding : PORTB = $00
    Lookup n, [$3F, $06, $5B, $4F, $66, $6D, $7D, $07, $7F, $67], Segments
    PORTB = $00
    PORTB = Segments
    pause 1
    PORTB = $00

    thanks for the really, very much appreciated
