Need Help for the Moving Message Display

[cmyew]

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 )

Sorry for my mistake that i din't stated clearly what type of display that i'm using.
i am using the LED dot matrix (8*8) and 74hc595 shift register

my circuit is similiar with the diagram below:

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

Nice design idea there.
