Another test... Copy from Arduino 1.8.13

/* Sharp IR Range Finder Implementation of Tim Bower's Virtual Triange Wall Follower.
* IRFollowWall
* Calibration has shown that the IR sensors can measure from 3.9 inches to 31.5 inches.
* This is a test using an A* Prime board with two Sharp IR Sensors and a servo to point the leftmost sensor perpendicular to the robot's pose.
* IRSensor1 - Pin: A2, 5V 
* IRSensor2 - Pin: A3, 5V
* The two IR sensors are mounted on a servo with a 45 degree angle between them.
* The coordinate frame is measured in inches.
* The (0,0) of the robot's frame is somewhere behind the two sensors.
* 
* NOTE: a positive AngleToWall => turn left
* a negative AngleToWall => turn right This seems like the opposite of a polar coordinate system, ie. substract to turn left, add to turn right
* 
* setM1Speed(int speed) 
* setM2Speed(int speed)
* setSpeeds(int m1Speed, int m2Speed)
* Speed should be between -400 and 400
* 
* Large parts of this sketch were browored from a Pololu compass demo.

```cpp int8_t PCintPort::addPin(uint8_t arduinoPin, PCIntvoidFuncPtr userFunc, uint8_t mode) { PCintPin* tmp; tmp=firstPin; if (firstPin != NULL) { do { if (tmp->arduinoPin == arduinoPin) { enable(tmp, userFunc, mode); return(0); } if (tmp->next == NULL) break; tmp=tmp->next; } while (true); } ```

Always copy the code from the editor, not the output console, and manually wrap it using triple backticks (```cpp and ```) for correct syntax highlighting.

void initialize() {
  float r, x, y;
  buildAngleArray(5.0f); // build out angle array at 5 degree increments
  for (int t = 1; t <= sampleSize; t++) {
    r = range[t];
    x = r * cosf(angle[t]);
    y = r * sinf(angle[t]);
    printf("range[%d]=%2.7f angle[%d]=%2.7f x=%2.4f     y=%2.4f\n",t,range[t],t,angle[t],x,y);
  }
  segmentation[0].start = 0;
  segmentation[0].end = 0;
  printf("end initialize() threshold=%2.7f\n\n",threshold);
  return;
}
