README

This is a simple WiFi oscilloscope using a STM32F303RE (Nucleo64) as the analog frontend (capturing analog samples) and an Onion Omega 2+ (acting as a serial-to-WiFi bridge and TCP server). A graphic frontend (written in Free Pascal / Lazarus) connects to the TCP server, collects and displays data.

TODO

  • improve operation (remove artifacts that sometimes appear on screen)
  • add auto-discovery feature
  • use two ADCs interleaving convertions to double the maximum sample-rate to 10Msps

Fabio

  • TCP server
  • frontend working
  • connection working

Divesh

capture sampled data

Charlie

  • work around code for the issue of sending '\n'
  • packet handler
  • common header which can be used commonly among frontend, onion and STM32
