Could someone write a little C code that loops through chars(1 byte,8 bits) and separates them into bits, in like other variables. I tried using shifts but if didnt work 2 good, Thanks alot

How about something like this: Your input char is c.

bool bit1 = c & 0x01;bool bit2 = c & 0x02;bool bit3 = c & 0x04;

etc.
Or even cleaner:

bool bits[8];for( int i = 0; i < 8; i++ ){  bits = c & ( 1 << i );}

void BitSeperator(unsigned char source,char *dest) // dest = pointer to char[8]
{
   for (char i=0;i<8;i++)
   {
       dest = source&1;
       source >>=1;
   }
}

I hope that''s the right code for you
