I have made moving message but I have a problem

codes for 74hc154 ;;;;;;;;;

Code:

#include <AT89x51.H>
#include <stdio.h>
#include <delay.c>
#define sayici P2 
const char A[]={0x00,0x7C,0x0A,0x09,0x0A,0x7C};
void main (){
for(sayici=0;sayici<7;sayici++){
P0=~A[sayici];
delay_ms(3);
}}

codes for 74hc138 ;;;;;;;;;;;

Code:

#include <AT89x51.H>
#include <stdio.h>
#define sayici P2 
#include <delay.c>
const char A[]={0x00,0x7C,0x0A,0x09,0x0A,0x7C};
void main (){
for(sayici=0;sayici<7;sayici++){
P0=~(A[sayici+1]);
delay_ms(3);
}}

but I want to do same thing with 74HC595 or CD4094

you can give me sample code
it can be in CCS or MikroC or Ansi-C(keil-iar)
but not in Asm or Pic basic :S

Do you really require them? You could just make a program for the same result minus the 74HC's

I just wanna do program for 8x8 dotmatris

I can use the demultuplexser Ic but I don't know use the serial to parallel Ic

if there is anyone who know to control 74hc595 or 4094,, can help me ???

I wanna just this

I did this project but I wanna do the same thing with 74hc595 or 4094 can yoou help me

Do you have a 74HC595 datasheet like here :http://www.tranzistoare.ro/datasheets/270/491765_DS.pdf ?
Its usage is straight forward, no addressing and no command structures. Just clock in 8-bit data with the Data and Clock. Then expose data to parallel with the Latch line. A beautiful raw interface. Most other pins are features that need not necessarily be connected to the Microcontroller.

ı wanna show the same character but I couldn't do it

help me

it will be shown on this schema
