Data logger tool for use with Arduino Uno R3/R4 products

Other Hardware Audio
1

I am in need of a tool for capturing digitalWrite data streams on the datapins of the Arudino Uno R3/R4. Does anyone have any suggestions? I need to record and analyze the output of Arduino that is using the FastLED library. I am interested in specific tools only. I understand that I am writing to the pin so that the info should be "known", however, for my needs on this project that is what I need for debugging/analyzing this specific project. Thank you.

Logic analyzers.

These work well (available from many outlets), are inexpensive and use open source control/display software.

Excellent! Thank you for the quick help!

  • FYI, this software has the ability to do graphing of such.

I use open source PulseView to plot the output of the logic analyzer linked above.
