This is a multiplatform software oscilloscope and logical analyzer. It supports Arduino (with custom firmware) and a Parallax USB oscilloscope.

• Panoramic view
• Load and save waveforms
• Zoom in and out
• Can open several waveforms at the same time
• Can run several oscilloscopes/logical analyzers simultaneously
• Frequency analysis using FFT
• Filtering, so far it has a low pass filter, probably more to come.
• Works on Windows and Linux (needs mono)
• Autodetects the hardware
• Post processing tools
  • Decodes fsk waves
  • Calculates wave main frequency using a few methods

• Arduino
• Parallax
