I can't put a bit in Data port, I use P1 for 74hc595, but when try to put a single bit from "char" there is nothing hapened

my source in K**l
BEGIN

#include <stdio.h>
#include <reg51.h>

sbit Data = P1^0;
sbit Pulse = P1^1;
sbit Lach = P1^2;
bit Carry = 0x03^0; ????????? i saw that in other code lilke 0x03.3


unsigned char t = 0x01;
unsigned char s = 0xC0;

void delay (const unsigned int);
void init(void);
void hcOut(unsigned int w);

void main(void)
{
init();
hcOut(0x0001);
}


void delay(const unsigned int period)
{
unsigned int x, y;
for (x = 0; x<= period; x++)
{
for(y=0; y<=60; y++);
}
}
void init (void)
{
P1 = 0x00;
P3 = 0x00;
P2 = 0x00;
Lach = 1;
Pulse = 0;

}
void hcOut(unsigned int w)
{
int q;
for(q =1; q<=16; ++q)
{
////////////HERE IS THE PROBLEM MAY BE //////////////////////
if (w^0 == 0){Data = 0;}
else if(w^1 == 1){Data = 1;}
w<<=1;
// Data = w^q;
Pulse = 1;
delay(10);
Pulse = 0;
delay(10);
/////////////--------------------------------------///////////////////
}
Lach = 0;
delay(10);
Lach = 1;
}

END

When i write a code One of my Port change hes state /like a counter/ i have no need of interups

 

[C-Man]

Try this:
////////////HERE IS THE PROBLEM MAY BE //////////////////////
if (w & 1){Data = 1;}
else {Data = 0;}
w>>=1;

You should also put an endless loop into main like this otherwise your program will restart continuosly:

void main(void)
{
init();

for(;
hcOut(0x0001);
}

hope this helps and best regards

how can i put some variables in flash i try 0x000000, but the plase is to small

in order i make my program like:
3 groups
OOOOOOOO|OOOOOOOO|OOOOOOOO
hcOut(0xsample, 0x00, 0x00)
hcOut(0x00, 0xsample, 0x00)
hcOut(0x00, 0x00, 0xsample)
this program run single dot

my idea is to connect a button to kontrol the mode of moving
