Touchdesigner-WIAnode kit Sample: LED Strip

Sensor Features: The LED strip is driven in real time based on the pixel color values of a TOP image in TouchDesigner.

Note: The control data format for the LED strip is RGB values × number of LEDs.

Input Data: Example with 3 RGB LEDs connected to the P1 port:

{"p1": "66 42 59 64 48 63 63 54 67"}

Quick Example: Graphic pixel values control the RGB LED strip.

Step 1: Configure the Port

Connect the WIAnode to your computer.
Open the USB drive that appears and modify the config.txt file by setting the P2 port to ws2812. Ensure that your Wi-Fi SSID and password are filled in.
Save the file. (Do not save the file multiple times.) Power cycle the WIAnode to restart it.

Step 2: Connect the Sensor

Use a 3-pin silicone cable to connect the LED strip to the P2 port on the WIAnode.
Align the wiring inlet with the arrow direction, as shown in the figure below.

Step 3: Connect TouchDesigner to WIAnode

Press the WKUP button on the side of the WIAnode to wake up the screen (it will turn off automatically after one minute of inactivity) and check the current device IP address.
Open the TouchDesigner example file, click on the WIAnode plugin, and enter the IP address shown on the WIAnode screen into the configuration panel. Enter wianode as the client name and dfrobot as the password.
Once the plugin displays Connected, the connection to the WIAnode is successful.
