    Hi all,

    I am new user for the pic microcontroller. Can anybody provide me some idea about how to scroll the text from right to left. i was using the pic16f877a and shift register to control it.

    Thanks.

    Hi,

    A closer look to your HD44780 compatible Display Datasheet could reveal it already offers this nice feature ...

    try , as command codes

    %0001 11xx
    %0001 10xx

    ... ( $FE, $1F and $FE,$1B )

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    I would love to see this thread ongoing and finally come up with a working circuit and code.

    Nice design idea there.
