What Will You Need?

  • IndusBoard with ESP32 microcontroller
  • RCA Audio/Video cable
  • Soldering kit
  • Jumper wires
  • Breadboard (optional)
  • Power supply for IndusBoard (USB or external)
  • Infrared (IR) receiver (optional)
  • Arduino IDE installed on your computer
  • ESPFLIX library (available here)

Step 1: Setting Up the ESPFLIX Library

Download the ESPFLIX Library:

  • Visit the ESPFLIX GitHub repository.
  • Download the repository as a ZIP file.

Install the Library in Arduino IDE:

  • Open Arduino IDE.
  • Navigate to Sketch > Include Library > Add .ZIP Library....
  • Select the downloaded ZIP file to add the ESPFLIX library.

Configure the Library:

  • Navigate to the Arduino libraries folder (usually found in the Documents folder).
  • Locate the ESPFLIX library and open the SRC folder.
  • Open the video.h file in a text editor.
  • Change the video pin from 25 to 18.
  • Change the audio pin from 25 to 26.

Step 2: Writing and Uploading the Code

Open the ESPFLIX Code:

  • Open the .ino file from the ESPFLIX library in Arduino IDE.

Select the Board:

  • Go to Tools > Board and select ESP32S2.

Upload the Code:

  • Connect your IndusBoard to your computer via USB.
  • Click the Upload button to upload the code to the board.

Step 3: Connecting the Hardware

Prepare the RCA Cable:

  • Cut one end of the RCA cable to expose the wires.
  • Identify the GND and signal wires.

Connect RCA Cable to IndusBoard:

  • Refer to the circuit diagram (Fig. 4).
  • Connect the signal wire of the RCA video to pin 18.
  • Connect the audio signal wire to pin 26.
  • Connect the GND wires of both RCA connectors to the GND pin on the IndusBoard.

Step 4: Testing the Setup

Power the Board:

  • Connect the power supply to the IndusBoard.

Control Options:

  • Optionally, connect an IR receiver to the board to control the device remotely.
  • You can also modify the code to use the built-in accelerometer and magnetometer as input devices.

Testing:

  • Once everything is connected and powered, your ESPFLIX device should be ready to use.
  • Connect the RCA cable to a TV or monitor to start streaming.

Additional Tips

Debugging:

  • If the video or audio doesn’t work, double-check the connections and ensure that the correct pins are used as configured in the video.h file.
  • Use the Serial Monitor in Arduino IDE to debug and check for any error messages.

Customization:

  • Explore the ESPFLIX library and modify the code to add more features or change existing ones.
  • Consider integrating other sensors or modules to enhance functionality.

ESPFLIX Library Setup: The ESPFLIX library is crucial for running the streaming functionality on the ESP32 microcontroller. By modifying the video.h file, you can customize which pins on the IndusBoard handle video and audio signals. This flexibility is key for adapting the ESPFLIX to various hardware setups.

Coding: The provided .ino file contains the main program for ESPFLIX. When you upload this code to the IndusBoard, it sets up the ESP32 microcontroller to handle video and audio streaming efficiently.

Connecting the RCA Cable: RCA cables typically have two internal wires: one for the signal and one for ground. Connecting these correctly to the designated pins on the IndusBoard ensures that the audio and video signals are properly transmitted to your TV or monitor.

Control Options: Using an IR receiver allows you to control the ESPFLIX device with a remote. Alternatively, modifying the code to utilize the IndusBoard’s built-in sensors can provide innovative ways to interact with the device, such as using gesture controls.
