What is HyperHDR?
HyperHDR represents a significant advancement in ambient lighting technology‚ designed to dynamically mirror the content displayed on your screen onto an LED strip․ It’s not merely a color-matching system; HyperHDR employs an advanced video pipeline that dramatically enhances the LED output‚ resulting in a remarkably smoother and more immersive experience․
Unlike traditional methods‚ HyperHDR focuses on capturing and processing the video signal to extract meaningful color and brightness information․ This allows for a more accurate and responsive representation of the on-screen content․ The system offers various connection options‚ including HyperSPI‚ HyperSerialESP32‚ and HyperSerialWLED‚ each catering to different hardware configurations and performance needs․ It’s a fork optimized for USB serial port connections at 2Mb speed․
The Role of ESP32 in HyperHDR
The ESP32 plays a crucial role in HyperHDR‚ acting as the central processing unit for controlling the LED strip and handling the incoming video data․ Its processing power enables the complex algorithms required for accurate color extraction and dynamic lighting effects․ Specifically‚ utilizing HyperSPI with the ESP32 unlocks data transfer speeds of up to 40Mhz‚ essential for high-density LED strips like the HD107․
Compared to the ESP8266‚ the ESP32 offers superior performance and connectivity options‚ making it the preferred choice for demanding HyperHDR setups․ It facilitates faster communication with the Raspberry Pi and allows for more complex lighting modes beyond those available in standard WLED or HyperSerialEsp8266․ The ESP32’s capabilities are key to achieving a truly immersive ambient lighting experience․
Why Choose SPI for HyperHDR?
SPI (Serial Peripheral Interface) is the optimal communication protocol for HyperHDR‚ particularly when paired with the ESP32․ Unlike HyperSerial‚ which relies on USB serial communication limited to 2Mb speed‚ HyperSPI achieves significantly faster data transfer rates – up to 40Mhz with the ESP32․ This speed is critical for driving larger LED arrays‚ like those using the HD107 strip‚ ensuring smooth and responsive lighting․
The increased bandwidth of SPI prevents buffering issues that can occur with HyperSerial when handling substantial data streams․ It also unlocks the potential for unique and advanced lighting modes unavailable with other methods․ While HyperSerialESP32 is an option‚ HyperSPI consistently delivers superior performance and reliability for a truly immersive HyperHDR experience․
Hardware Requirements
Essential components include an ESP32 development board‚ compatible LED strip (like HD107)‚ optional Raspberry Pi‚ and a Mean-Well LRS-150F-5 power supply․
ESP32 Development Board
The ESP32 is the core of this project‚ chosen for its robust processing power and‚ crucially‚ its support for high-speed SPI communication․ This capability is vital for driving HyperHDR with larger LED counts and achieving the desired 40Mhz data transfer rates‚ particularly when using HD107 LED strips․
Any standard ESP32 development board will generally suffice‚ but consider models with sufficient GPIO pins to accommodate the SPI interface (SCK11‚ MISO9‚ MOSI10 when using the default spidev0․0 configuration) and the LED strip data line․ Ensure the board can handle the power requirements of the LED strip‚ or plan for external power solutions․ The ESP32’s ability to handle complex data processing makes it ideal for HyperHDR’s advanced video pipeline․
LED Strip Compatibility (HD107 and others)
HyperHDR shines with addressable LED strips‚ and the HD107 is a popular choice due to its high density and vibrant colors․ However‚ compatibility extends beyond just HD107; many other RGB and RGBRGBW strips can be utilized; The key is ensuring the chosen strip is controllable via a single data line and supports the appropriate color order․
The RGBRGBW algorithm is crucial for strips with dedicated white LEDs‚ differing from the standard WLED approach․ When working with larger LED numbers‚ the ESP32’s SPI interface becomes essential‚ as serial buffers might become insufficient for timely data transfer․ Consider the current draw of your chosen strip and select a suitable power supply‚ potentially needing an XT60 connector for higher currents․
Raspberry Pi Integration (Optional)
While the ESP32 handles the LED data transmission via SPI‚ a Raspberry Pi often serves as the central processing unit for HyperHDR‚ capturing HDMI video and processing it for ambient lighting․ The Pi requires Raspberry Pi OS and connects to the ESP32‚ typically using a USB connection․ An HDMI capture card plugged into the Pi’s USB port (bottom left closest to Ethernet is often best) is vital for video input․
An HDMI splitter is commonly used‚ directing one output to the Pi (with the scaler switch on) and another to your TV (scaler off)․ Some users employ a Zigbee relay to remotely control power to the Pi‚ ESP32‚ and USB splitter‚ avoiding manual unplugging․ Remember the Pi uses a dedicated 2A USB power supply‚ separate from the ESP32’s power source․
Power Supplies (Mean-Well LRS-150F-5)
Reliable power is crucial for a stable HyperHDR setup․ The Mean-Well LRS-150F-5 is a recommended power supply‚ providing 5V DC output suitable for both the ESP32 and the LED strip․ It’s important to note the Raspberry Pi requires its own dedicated 2A USB power supply and should not be powered by the Mean-Well unit․
For connecting the LED strip‚ a Molex connector is suggested for lower currents‚ but for higher demands‚ consider an XT60 connector or equivalent․ The Mean-Well unit requires an IEC 320 3-pin 10A 250V socket (C14 input) with a 1A fuse for safety․ Proper mounting‚ potentially with screws‚ ensures a secure and organized installation of the power supply alongside the ESP32 and Raspberry Pi․
Software Setup
HyperHDR installation and ESP32 configuration are key first steps․ Configure the ESP32 for SPI communication‚ utilizing settings like spidev0․0 (SCK11‚ MISO9‚ MOSI10)․

For extensive setups‚ ensure adequate power delivery and consider utilizing higher-current connectors like XT60․ HyperSPI’s 40Mhz data transfer capability‚ exclusive to the ESP32‚ further enhances performance with numerous LEDs‚ delivering a smooth and responsive ambient lighting experience․ Careful planning is key to a successful large-scale installation․
Advanced Features and Troubleshooting
HyperHDR offers HDR to SDR switching to prevent black screens‚ alongside HDMI capture card integration for diverse input sources and seamless operation․
HDR to SDR Switching
HDR to SDR switching is a crucial feature within HyperHDR‚ specifically designed to address the common issue of a “black screen” when processing HDR content․ Without this functionality‚ the ESP32 may struggle to correctly interpret and display HDR signals‚ resulting in a loss of video output․ Enabling this switch within the HyperHDR software effectively converts the HDR video stream into a Standard Dynamic Range (SDR) format․
This conversion allows the ESP32 and connected LED strip to accurately reproduce the colors and brightness levels‚ ensuring a consistent and visually appealing ambient lighting experience․ It’s a simple yet powerful solution to a potentially frustrating problem‚ making HyperHDR more user-friendly and reliable for a wider range of HDMI sources and display configurations․
HDMI Capture Card Integration
Integrating an HDMI capture card is essential for feeding video signals to the Raspberry Pi‚ which then processes the data for HyperHDR․ The capture card allows the system to intercept the HDMI stream from a source device‚ like a game console or media player‚ before sending it to the ESP32 for LED synchronization․ Experimentation with different USB ports on the Raspberry Pi is often necessary to find the most stable connection; the port closest to the Ethernet port seems to perform optimally․
Proper placement and configuration of the capture card are vital for reliable video capture and a seamless ambient lighting experience․ A dedicated 2A USB power supply for the Raspberry Pi‚ separate from the Mean-Well power supply‚ is also recommended for optimal performance․
Dealing with “Black Screen” Issues
A common problem encountered during HyperHDR setup is a “black screen” – where no video is displayed on the LED strip․ This often arises from incorrect HDR to SDR switching settings within the HyperHDR software; Enabling the HDR to SDR switch can resolve this issue‚ effectively converting the high dynamic range signal to a standard dynamic range format compatible with the LED strip and ESP32․
Furthermore‚ ensure the HDMI splitter is configured correctly‚ with HDMI OUT 1 going to the Raspberry Pi (scaler switch On) and HDMI OUT 2 to the TV (scaler switch Off)․ Troubleshooting USB port connections for the HDMI capture card is also crucial for a stable signal․
