ESP8266-WS2811

Requirements

• Linux (I've not tried other environments)
• The esp-open-sdk
• An environment variable "ESP_ROOT" pointing to the root of the above sdk
• An addition to the PATH environment variable, pointing into $ESP_ROOT/xtensa-lx106-elf/bin/

Setup

• Copy the user_config.h.template header to user_config.h (Within the include/ directory) and enter your SSID and password.
• Get your hardware setup - the signal will be sent to the uart RX pin - see the KiCad project and schematic in pcb/ for more information.
• Connect your ESP and find out which port it is connected to.
• Get your ESP ready for flashing over UART
• Comile and flash by running make flash PORT=<esp>, where <esp> would usually be something like /dev/ttyUSB0

The protocol

You can then control the led strip by sending UDP packets with the following format:

[Packet] 	:= [LED] * ledCount
[LED]		:= [r: byte][g: byte][b: byte]

Example:

Set the first driver to magenta:

byte[] packet = new byte[]{0xFF, 0x00, 0xFF};
