This Artnet ESP32 LED controller is a high-performance, open-source solution for controlling addressable LEDs using Ethernet or Wi-Fi. This project allows you to control multiple LED strips using the Artnet protocol via an ESP32 microcontroller with a W5500 Ethernet module or ESP32-ETH01. The code includes a simple web server for configuration and control of the LED strips. For optimal performance, use the W5500 as the ETH01 suffers from performance issues.

All LEDs based on the wsXXXX series are supported. These can be 3, 4 or even 5 channel LEDs, as long as they have single data line and 800Khz timing. These include but are not limited to:

• WS2805, WS2811, WS2812, WS2813, WS2814, WS2815 (Tested)
• SK6812, SK6812W, SK6812-mini (Not tested)
• GS8208, TM1814, TM1829, UCS8904, UCS8903, FW1906 (Not tested

• After uploading the code, connect your ESP32 to a network using the W5500 Ethernet module.
• Set core debug level to "info" for extra infomration on performance
• Find the IP address assigned to the ESP32 and open it in a web browser.
  • To find the IP address easily, use Resolume advanced output. It will autodetect the Artnet node.

Upload the BIN file to your Node to have OTA updates. Easy when your node is in a hard to reach or remote place!

• After 30 seconds without any Ethernet response, an AP mode will automatically launch
• You can use this to connect to the Node and set up settings or a Wifi connection.

Important! Be sure that the Universes/outputs/leds always match what you output. A mismatch can result in a black output.

• Default led strip pins are 12, 14, 27, 26 (more outputs can be added if necessary. Change config accordingly).
• Default status led is set to pin 16.
• Pin 16/17 can be reprogrammed for new functionality/adding more outputs. (They are connected to the 5v level shifter).
• I2C pins for OLED are set to pins 21 and 22.
• The default timeout is set to 30 seconds.
• There is a 5V switch Where the 12v regulator sits. Use this if you power the node with 5v Intead of 12V! The esp and other logic will be powered from the 5v power supply instead of the 12v to 5v regulator.

Sadly, the W5500 does not support Auto-MDI/MDIX, which means you need a crossover cable whenever you want to connect directly from your PC to the Node with an Ethernet cable!

#Basic resolume setup example To get you up and running with your node, I provide a basic setup example for Resolume. Other software will work similarly.

1. Connect your node to a router (DHCP) or switch (Static IP) through Ethernet, wifi, or AP mode (192.168.4.1).
2. Once your node is successfully connected to your network, navigate to the configuration page (192.168.1.xxx) and set the Node's Name, Number of outputs, and MAXIMUM Leds you connect to your output.
3. Optional) Enable the RGB test cycle or Static color to test if all ouputs and LEDs behave as expected.
4. In Resolume, set the correct network adapter in Preferences>DMX.
5. In Resolume's advanced output, add a new Lumiverse and add the LED strips.
6. In Resolume's advanced output, set the IP address.
7. The node supports 4 universes (680 LEDS) per output. If you need all 16 universes (680 leds per output), add 4 Lumiverse outputs and set the right universes per output. For output 1 that is start universe 0, For output 2 that is start universe 4, For output 3 that is start universe 8, For output 4 that is start universe 12. Change this corresponding to the number of universes per output that you need.
8. Your strips should now light up!
