SpinWheel Basic Programming Interface

The SpinWheel library SpinWearables.h has a number of easy to use functions with which to build elegant new visual patterns. A typical SpinWheel demo would have this general form:

#include "SpinWearables.h"
using namespace SpinWearables;

void setup() {
  // Prepare the SpinWheel hardware, in particular the
  // built-in motion sensor.
  SpinWheel.begin();
  
  // Set the overal brightness of the large LEDs.
  // It can be necessary if you want to avoid blinding
  // the people around you.
  SpinWheel.largeLEDs.setBrightness(20);
}

void loop() {
  // Ensure that recent motion data is 
  // read from the motion sensor (a.k.a. IMU,
  // a.k.a. Inertial Measurement Unity).
  // This is not necessary if you are not using
  // the motion measurements.
  SpinWheel.readIMU();
  
  // Here you add any drawing code you might want.
  // ...
  // ...

  // And finally, you command the SpinWheel to
  // display the drawing you have prepared.
  SpinWheel.drawFrame(); 
}

If you want to clear a previously drawn frame (as opposed to draw over it) you can use the SpinWheel.clearAllLEDs() function. Or you can use SpinWheel.clearSmallLEDs() or SpinWheel.clearLargeLEDs() if you want to erase only the small or large LEDs.

If you want to set all small LEDs to a single color, you can use SpinWheel.setSmallLEDsUniform(r, g, b) where r, g, and b are the red/green/blue components of the color to be shown (in the range from 0 to 255).

Similarly you can use SpinWheel.setLargeLEDsUniform(r, g, b) to set the color of all large LEDs.

The functions SpinWheel.setSmallLED(i, r, g, b) and SpinWheel.setLargeLED(i, r, g, b) set the color of only one LED (the one indexed by the number i). This number goes from 0 to 11 for the small LEDs and from 0 to 7 for the large LEDs.
