HackRF Sweep WebUSB

This is a spectrum analyzer implementation in JavaScript with WebUSB for HackRF.

Usage

There are no requirements except a browser supporting WebUSB (available by default with Google Chrome currently)

  1. Access to https://cho45.stfuawsc.com/hackrf-webusb/ .
  2. Connect your HackRF to USB port.
  3. Click [CONNECT] and select the device.
  4. Set range for analysis.
  5. Click [START].
  6. Adjast gains.

Implementation

  1. Communication with HackRF device with WebUSB.
  2. Run FFT with WebAssembly which is written in Rust (using RustFFT)
  3. Show results with WebGL waterfall implementation.
You can’t perform that action at this time.
