Hi Ittipong
Here is quick example:
#include <stdio.h>
#include <string.h>
#define UINT8 unsigned char
void display(UINT8 * buffer, UINT8 Length){
UINT8 * tmp = buffer;
UINT8 mask;
int i, y;
for (i = 0; i < Length; i++) {
mask = 1;
printf ("Printing byte 0x%02X, bits = ", *tmp);
for (y=0; y < 8; y++ ){
printf ("%X,", (*tmp & mask) >> y);
mask = mask << 1;
}
printf ("\n");
tmp ++;
}
}
int main ()
{
UINT8 buff[3]= {0x01, 0xAA, 0x03,};
UINT8 len = sizeof(buff);
display(buff, len);
return 0;
}
The output is:
Printing byte 0x01, bits = 1,0,0,0,0,0,0,0,
Printing byte 0xAA, bits = 0,1,0,1,0,1,0,1,
Printing byte 0x03, bits = 1,1,0,0,0,0,0,0,
