The example code has been uploaded to github under the MIT Open Source License. These examples demonstrate basic functions of the HMD, text, led control, and sound. There is a routine in the android example that mirrors the text to make it appear correct in the eyepiece. Please comment if anyone has questions or problems with the example code.
