stop LED blinking on claim()

[weisjohn]

The controller blinks the LED around the xbox button continually, which is actually quite annoying. We should make the light go solid when we claim() and blink again when we release() #9

I found a reference from an Arduino project: https://dilisilib.wordpress.com/hacking/xbox-360-rf-module-arduino/. An excerpt incase of rot:

int led_cmd[10] =  {0,0,1,0,0,0,0,1,0,0}; //Activates/initialises the LEDs, leaving the center LED lit.
int anim_cmd[10] = {0,0,1,0,0,0,0,1,0,1}; //Makes the startup animation on the ring of light.

void sendData(int cmd_do[]) {
  pinMode(data_pin, OUTPUT);
  digitalWrite(data_pin, LOW);    //start sending data.
  int prev = 1;
  for(int i = 0; i < 10; i++){

    while (prev == digitalRead(clock_pin)){} //detects change in clock
    prev = digitalRead(clock_pin);
      // should be after downward edge of clock, so send bit of data now
    digitalWrite(data_pin, cmd_do[i]);

    while (prev == digitalRead(clock_pin)){} //detects upward edge of clock
    prev = digitalRead(clock_pin);
  }
  digitalWrite(data_pin, HIGH);
  pinMode(data_pin, INPUT);
}
