You can program the lumiSTEP online WLED program using a USB cable at https://install.wled.me/. Edge and Chrome browsers are supported.
COM port not found
If the COM port is not found after connecting the lumiLED using the USB-C cable, press the RESET and FLASH buttons simultaneously for 3 seconds. Then release the RESET button and after a second, the FLASH button. The device will enter boot mode and the COM port will be found.
How it works
What are intelligent (addressable) LEDs
Intelligent LEDs, also known as addressable RGB LEDs, allow individual control of each LED in a strip or matrix - both its colour and intensity separately. Each LED (e.g. WS2812B, often referred to as NeoPixel) has an integrated microcontroller that receives digital data and determines how a particular LED should be lit. Control is via a single data wire, which greatly simplifies wiring even with a large number of LEDs.
Functionality and benefits
- 24-bit color depth: each LED supports 8 bits for red, green and blue, allowing more than 16 million color combinations to be displayed.
- Individual control: Each LED can be controlled individually, allowing you to create complex lighting effects and animations.
- Easy interconnection: the LEDs are connected in series, with the data signal passing through all LEDs, simplifying cabling.
- High brightness and rich colours: thanks to integrated drivers and high-quality LED chips, these LEDs achieve high brightness and accurate colour rendering.
Technical details
- Power supply: LED 5V DC, LED strips with supply voltage 5V, 12V, 24V
- Data protocol: DC data stream with precise timing (e.g. WS2812 protocol)
- Data Input/Output: Each LED has a data input and output, allowing multiple LEDs to be daisy chained.
- Memory: Each LED has an internal memory to store the current color state, ensuring stable illumination even when the data signal is interrupted.
Power supply and consumption
- Consumption per LED: At full brightness (white), each LED consumes approximately 60 mA.
- Strip consumption: A strip with 144 LED/m may require more than 8 A at 5 V.
- Power: It is recommended to feed voltage through multiple points, especially for longer strips, to avoid voltage drop and color distortion.
- Protection: It is recommended to use an electrolytic capacitor (e.g. 1000 µF) on the power line to increase stability and a fuse rated for the nominal current of the LED strip.
Available formats
- Standalone LED chips (SMD): for custom designs and mounting on printed circuit boards.
- LED strips: Available with different LED densities (e.g. 30, 60, 144 LED/m). Different supply voltages (e.g. 5V, 12V, 24V, 48V).
- Modules: Circular, square and matrix modules (e.g. 8×8, 16×16) for various applications.
- Shields for development boards: modules compatible with platforms such as Arduino or ESP32.
Usage
- Ambient lighting: creating mood lighting in interiors.
- Advertising and exhibition panels: dynamic lighting effects to attract attention.
- Music projects: synchronising lighting effects with music.
- Interactive displays: Displaying text, animations and graphics.
- Wearable electronics: Decorative and functional lighting for clothing and accessories.
Install WLED
You can program the lumiSTEP online WLED program using a USB cable at https://install.wled.me/. Edge and Chrome browsers are supported.
Programming procedure
Disconnect the lumiSTEP from the power supply. Connect the lumiSTEP to the computer using the USB-C cable. Open a browser (EDGE or Chromium). Click on the link https://install.wled.me/. Select the WLED version. Press the Install button. After pressing the Install button, a pop-up window will appear with the selection of the COM port. Select the COM port labeled USB JTAG/serial debug unit (COMxx). Press the Connect button. After the Device Dashboard window appears, press the INSTALL WLED button. After pressing the button, the Confirm Installation window appears. Press the INSTALL button. After pressing the INSTALL button, the installation will begin. After the installation is complete, disconnect the device from the USB-C cable and connect the device to the power source. WELL DONE
