+Fadecandy: Open Pixel Control Protocol
+======================================
+
+The Fadecandy Server (`fcserver`) operates as a bridge between LED controllers attached over USB, and visual effects that communicate via a TCP socket.
+
+The primary protocol supported by `fcserver` is [Open Pixel Control](http://openpixelcontrol.org), a super simple way to send RGB values over a socket. We support the standard Open Pixel Control commands, as well as some Fadecandy extensions.
+
+Socket
+------
+
+Open Pixel Control uses a TCP socket, by default on port 7890. For the best performance, remember to set TCP_NODELAY socket option.
+
+Command Format
+--------------
+
+All OPC commands follow the same general format. All multi-byte values in Open Pixel Control are in network byte order, high byte followed by low byte.
+
+Channel    | Command   | Length (N) | Data
+---------- | --------- | ---------- | --------------------------
+1 byte     | 1 byte    | 2 bytes    | N bytes of message data
+
+Set Pixel Colors
+----------------
+
+Video data arrives in a **Set Pixel Colors** command:
+
+Byte   | **Set Pixel Colors** command
+------ | --------------------------------
+0      | Channel Number
+1      | Command (0x00)
+2 - 3  | Data length
+4      | Pixel #0, Red
+5      | Pixel #0, Green
+6      | Pixel #0, Blue
+7      | Pixel #1, Red
+8      | Pixel #1, Green
+9      | Pixel #1, Blue
+…      | …
+
+As soon as a complete Set Pixel Colors command is received, a new frame of video will be broadcast simultaneously to all attached Fadecandy devices.
+
+Set Global Color Correction
+---------------------------
+
+The color correction data (from the 'color' configuration key) can also be changed at runtime, by sending a new blob of JSON text in a Fadecandy-specific command. Fadecandy's 16-bit System ID for Open Pixel Control's System Exclusive (0xFF) command is **0x0001**.
+
+Byte   | **Set Global Color Correction** command
+------ | ------------------------------------------
+0      | Channel Number (0x00, reserved)
+1      | Command (0xFF, System Exclusive)
+2 - 3  | Data length (JSON Length + 4)
+4 - 5  | System ID (0x0001, Fadecandy)
+6 - 7  | SysEx ID (0x0001, Set Global Color Correction)
+8 - …  | JSON Text
+
+Set Firmware Configuration
+--------------------------
+
+The firmware supports some runtime configuration options. Any OPC client can send a new firmware configuration packet using this command. If the supplied data is shorter than the firmware's configuration buffer, only the provided bytes will be changed.
+
+Byte   | **Set Firmware Configuration** command
+------ | ------------------------------------------
+0      | Channel Number (0x00, reserved)
+1      | Command (0xFF, System Exclusive)
+2 - 3  | Data length (Configuration Length + 4)
+4 - 5  | System ID (0x0001, Fadecandy)
+6 - 7  | SysEx ID (0x0002, Set Firmware Configuration)
+8 - …  | Configuration Data
+
+Current firmwares support the following configuration options:
+
+Byte Offset | Bits   | Description
+----------- | ------ | ------------
+0           | 7 … 4  | (reserved)
+0           | 3      | Manual LED control bit
+0           | 2      | 0 = LED shows USB activity, 1 = LED under manual control
+0           | 1      | Disable keyframe interpolation
+0           | 0      | Disable dithering
+1 … 62      | 7 … 0  | (reserved)
