convert string representing a binary number to binary

Question

I have a serial input "1111111" and I would like to convert this to a binary B1111111 that I can send to a led matrix.

I tried to search, but, all the results were misleading, led to full text to binary conversion. Please advise.

edit: This is my sample code where I am missing a step in the conversion part

LedControl mat = LedControl(DIN_PIN, CLK_PIN, CS_PIN, MAX_SEG); // MAX7219
void OneLine() {

//input
char text[] = "11111110";
//convert to binary number somehow


//show one line
      mat.setRow(0, 0, convertednr);
}

Answer 1

As pointed out by @EdgarBonet, I can convert the string to binary number with strtoul() and pass this to my led control. Adding this as an answer for future readers:

 LedControl mat = LedControl(DIN_PIN, CLK_PIN, CS_PIN, MAX_SEG); // MAX7219
void OneLine() {

//input
char text[] = "11111110";
//convert to number
uint32_t convertednr = strtoul(text, NULL, 2);
//print out
mySerial.println(convertednr);

//show one line
      mat.setRow(0, 0, convertednr);
