How to Send Audio File in DE1-SoC FPGA?
To send audio files to your DE1-SoC FPGA board , you'll need to follow these general steps: Method 1: Using Audio Codec via Line-In Connect audio source : Use the 3.5mm audio jack (Line-In) on the DE1-SoC board Connect your audio source (computer, phone, etc.) using an audio cable FPGA Design : Implement the audio codec interface (WM8731 on DE1-SoC) Configure the codec via I2C Process incoming audio data in your FPGA design Method 2: Loading Audio Files via SD Card Prepare SD card : Format SD card as FAT32 Convert audio file to raw PCM format (e.g., using Audacity or SoX) Save file to SD card FPGA Design : Implement SD card controller Read audio data from file Send to audio codec or process as needed Method 3: Sending via UART/USB (Slower) Convert audio file : Downsample if needed (DE1-SoC typically handles 48kHz) Convert to raw PCM format FPGA Design : Implement UART or USB receiver Buffer incoming audio data Send to audio codec Example VHDL/Verilog Components Needed: Audio code...
