Encoders for ETC Eos

A 9-encoder (un-official) add on to the ETC Eos Family of Lighting Consoles and Software, using OSC over USB.

This is an independent project that is designed to work with the ETC Eos, but not affiliated with Electronic Theatre Controls in any way.

Quick Start

To build the hardware, consult the README located in the Hardware folder.\ To make changes to the firmware, consult the README located in the Firmware folder.

1. Connect the encoders to your console, PC or Mac using a USB-A to micro-USB cable.
2. Start up the ETCnomad software or Eos family console.
3. Navigate to Settings > System > Show Control > OSC in the software, and ensure OSC USB is enabled.\
4. Reboot the console or restart the software.
5. The left-hand status indicator on the encoders should change from orange (not connected) to green (connected).
6. Select a channel in the Eos console or ETCnomad software, the encoders will update with any parameters applicable to the selected page.
7. Select the page to adjust desired parameters:\
   • 1st (red) button: Intensity, focus and beam parameters
   • 2nd (amber) button: Colour parameters (press multiple times to switch between the 3 layouts).
   • 3rd (green) button: Not used - for future use.
   • 4th (blue) button: Framing shutters
8. Adjust parameters by spinning the encoder clockwise or anti-clockwise. A fine mode can be toggled on or off by pushing the encoder in.\

Usage

The Encoders consist of the following components:

• 9x Encoders each with integrated push-button, a small 10x2 display and RGB LED
• 4x Page-select buttons in red, amber, green and blue.
• 2x Auxilary buttons for future use.
• 3x Auxilary RGB LEDs for status feedback and future use.
• 1x Micro-USB socket for connection to the console, PC or Mac.
• 512kB of memory for future use, such as storing custom user configuration of page layouts.

Status LEDs

The three RGB LEDs on the right-hand side of the provide some basic functionality feedback:

• The left-hand LED is orange when not connected to any Eos software or console, green when connected.
• The middle LED is not used, reserved for future use.
• The right-hand LED flashes a dim cyan at 1Hz to indicate the encoder firmware is still running its main loop (for debugging purposes).

Page Select Buttons

The four page select buttons allow the user to choose the group of parameters they wish to adjust:

1. The first (red) button has a single layout for intensity, focus and beam adjustments:\
2. The second (amber) button has three layouts for colour adjustments:
   1. CMY Layout:\
   2. RGB / x7 Layout:\
   3. x7 Adjust Layout:\
3. The third (green) button currently has no layout and is for future use.
4. The fourth (blue) button has one layout for framing shutter adjustments:\

Auxilary Buttons

The two circular buttons on the right hand side are currently not used and reserved for future use.

Compatibility

The encoders will not work on any Win XPe-based consoles. It should work on any Win 7e-based Eos consoles, as well as any version of the ETCnomad software that supports OSC-over-USB. See the ETC Lighthack GitHub page:

Eos supports this functionality on Win7e-based consoles and ETCnomad for Windows in software version 2.6.1 and newer, and on ETCnomad for Mac in software version 2.7.0 and newer.

Support for XPe-based consoles or XP computers is not planned for this project. Many XPe-based consoles can be upgraded to Win7e to make them compatible with #lighthack.

As the Lighthack project was intended for the Arduino Uno (and this project uses a Teensy 3.2), the USB Vendor ID and Product ID had to be spoofed so the encoder board looks like an Arduino instead of a Teensy. Eos consoles will ignore OSC messages from USB devices that do not have the Arduino Uno Vendor ID and Product ID.
