joystick sensitivity

[Joshua May]

One thing we did was add in a "deadband" to the center of the joysticks, which has really helped. The code makes use of an absolute value function that we created. Today, we'll also be adding a ramping function to the joysticks just like what was described above, I can get you that code too if you need it.

#define DEADBAND 10

int abs(int x)
{
  if (x >= 0)
    return x;
  else
    return -x;
}

if (abs((p1_y - 127)) < DEADBAND)
  p1_y = 127;

if (abs((p1_x - 127)) < DEADBAND)
  p1_x = 127;
