EnchantOS Lightsaber Firmware 1.0.6 – A .hex file, ready to be uploaded with the Teensy loader.

Lightsaber SD Card Files – An example set of SD card files, including the following:

  • 3 sound fonts using the Enchant style naming convention
  • 1 sound font using the Classic style naming convention
  • config.txt – An example config file with default settings

Operation

The software organizes interactions with the prop though an intuitive Menu system. The change Menu function (hold the power button) will cycle through the top level menu: Light FX Menu, Saber FX Menu, and Music Visualizer Menu. Pressing the Aux button within each Menu will act depending on the Menu e.g. The Aux button is used in the Light FX Menu to switch between different Light FX.

Button Light FX  Saber FX  Music Visualizer Power Off
Power Click Power On / Off Power On / Off Power On / Off Power On
Aux Click Pattern Option Blaster Next Song
Power Hold Next Menu Next Menu Next Menu
Aux Hold Next Pattern Next Pattern Next Font

Hibernate

The saber will enter a low power state after a period of inactivity, 1 minute by default. Pressing the red button switch will boot the saber. After taking a moment to boot, pressing the red button switch again will ignite the blade.

Sound Font

WAV files are accepted in 44.1kHz mono or stereo. Audacity can be used to convert the sampling frequency, as well as repair wav files with invalid headers.

It is recommended that any file edits, such as renaming, be done in directory other than the SD card; then copy what would be the entire contents of the SD card onto the SD card. This way Windows regenerates any metadata regarding Short File Names and directory contents.

3 fonts can be accessed on the SD card (this can be increased at a later software update). Up to 16 different .wav files can be mapped to 1 sound effect.

The software supports 2 different naming conventions for mapping sound fonts: Enchant Style and Classic Style.

Enchant Style

The contents of the SD card should appear as follows:

With Enchant Style, the name of each sound effect is the name of each subdirectory under the font directory.

“bank1” is the name of the font (This name can be changed in the config file). It subdirectories: “PowerOn”, “PowerOff”, etc, contain the wav files mapped to the function suggested by the name.

Classic Style (support will be implemented in a later update)

The contents of the SD card should appear as follows:

With Classic Style, the name of each sound effect is a prefix for each sound file. All files are saved in the directory of the font.

“bank3” is the name of the font (This name can be changed in the config file). “poweron.wav”, “clash1.wav”, etc, are mapped to the function suggested by the name.

SmoothSwing

Original description

SmoothSwing will use 2 addition sets of sound effects: “SwingA” and “SwingB”. If Enchant style is selected, they will be the name of subdirectories set to contain .wav files. E.g bank1/SwingA/anyname.wav

Uploading the Software

It is very easy to use the Teensy firmware flash utility to upload the firmware. The entirety of Teensy development tools can be downloaded from PJRC, or just download the flash utility here. This is the only part we need for this step.

Select the hex file. Then, click the button on the Teensy to enter the bootloader, as the flash utility indicates. Press the program button on the flash utility to upload the program. Once that is done, click the reset button to reset the device.
