Arduino Logic Analyzer

A simple logic analyzer, which can be used with any Arduino and Python3.

  • Upload the firmware.ino sketch to your Arduino
  • Find out to which COM-Port your device is connected
  • Adjust the COM-Port in interface.py
  • Run interface.py to record data from arduino and plot the result
  • You can also open serial interface (e.g. over arduino ide) can copy the received data in a csv-file
  • You can then plot with plot.py

Hints:

  • You can choose your pins in the Arduino sketch
  • You can choose your sampling rate in the Arduino sketch

Example

This is how an example application could look like:

The resulting plot could look like this:
