What is the best signal interface for PC ?

-Was my answer clear enough after all? (as short as it was)

Hello. My#117 refers to my #115.

I think we have been at 'cross purposes':

I actually made the entire movinglight program like I did it with arduino..... in binary format and then converted in hexa and finally converted to encrypted bin file; But because that counter is counting to 5, is only displaying only the first 5bytes in the program. Im still thinking.... I made some previeous tests before this moving thing here and I can lit every individual led in the matrix if I find its coresponding byte code. Im very close....like that.

also a second movie to show you the progress and the problems as well.

Proteus sim p5 - I finished the logic to drive the Led Matrix Display

@marconi I believe you pressed a button and switch back and forth the letters already saved in the memory. You advanced 1 step that memory location with a press of a button. I observed/remember right?
Also I need help in this detail because is a bit too hard for me. Tell me how to advance to the next character.
Thank you.

Tell me how to advance to the next character in the RAM ? How you did it? I believe you pressed a button to do it, but how it was wired? please detail it for me. Thank you.

@marconi check this out, its on it's way before your package. It should arrive soon.
So I will have 2 RAM types to experiment with.

Before I wade in with any help(?) please clarify for me how you intend your logic to scan the LEDs of the 7 x 5 matrix. ie led by led, a column of 7 LEDs column by column left to right and then repeat or a row of five leds row by row top to bottom and then repeat.

My scheme is to scan the display column by column left to right and then repeat as in the attachment. In this test sequence the complete column of 7 LEDs is lit up, column by column.

Its not clear from my #125 movie?
here is the entire circuit diagram.
