Skywriter Arduino Library

Installation

Place the Skywriter library folder into Arduino/libraries folder.

Usage

Skywriter is instantiated for you, just include the header file:

#include <skywriter.h>

And you'll have a "Skywriter" object ready to go.

Fire it up in your setup function like so:

void setup(){
  Skywriter.begin(PIN_TRFD, PIN_RESET)
}

To check for a new data packet, you must "poll" Skywriter in your main loop, like so:

void loop(){
  Skywriter.poll()
}

To handle an incoming XYZ update, gesture, airwheel or touch you should create a handler function. This example shows XYZ coordinates being output to Serial:

#include <Wire.h>
#include <skywriter.h>

void setup() {
  Serial.begin(9600);
  while(!Serial){};
  Serial.println("Hello World!");

  Skywriter.begin(PIN_TRFD, PIN_REST);
  Skywriter.onXYZ(handle_xyz);
}

void loop() {
  Skywriter.poll();
}

void handle_xyz(unsigned int x, unsigned int y, unsigned int z){
 char buf[17];
 sprintf(buf, "%05u:%05u:%05u", x, y, z);
 Serial.println(buf);
}
