You could make it into an array by calling a function which will shift a bit to the correct location, then ANDing it to test it, then returning TRUE/FALSE like this :-


byte GetAt(byte data,byte idx)
{

return ( data & (1<<idx));
}

then use :-

byte MyData=54;

for(i=0;i<8;i++)
{
if(GetAt(MyData,i))
{
printf("Bit %d was SETn",i);
}
else
{
printf("Bit %d was CLEARn",i);
}
}


It isn't efficient. but it will work.
