string to byte

Using Arduino Programming Questions
1

Hello,
I know that this topic has been raised before, however, I failed to find the answer i am looking for.
I have the following string:

String S = "0b00001111";

I need it to become the following byte

byte B = 0b00001111;

so that I can later put it into the following array

byte B_array [8] = (0b000000000,
                             0b000000000,
                             0b000000000,
                             0b000000000,
                             0b000000000,
                             0b000000000,
                             0b000000000,
                             0b000000000);

I have already tried this:

B = byte (S.toInt());

and it doesn't work as expected - it just creates a single integer out of the String. (or better it actually works as it says but this is not what I want it to do.
B = byte (S); doesn't work either

I don't think there exists such a function. So you have to interpret it yourself.

Ok, fine, however, is there a way to add bits to a byte? Can I use byte as an array of sorts?

byte B = 0b00011111;

B[2] = 1;

B = 0b10011111;
?

String s = "0b00110011";
byte b = Byte.parseByte(s);

Throws NumberFormatException if the string cannot be parsed.

What's wrong with bitWrite.

Why are you using a String in the first place? Where does the value in the resource-wasting String come from? Sending data intelligently is better than struggling to convert the crap you get to the form you want.

There are ways to add, subtract, shift left, shift right, AND, OR, NAND, NOR, XAND, XOR etc. bits in a byte. You can use a struct to declare names for the bits in a byte, and access them by name.
