Because PLX-DAQ v2.11 is an open-source community optimization of the original Parallax software, it is primarily hosted on the official Arduino Forum and community repositories.
Turn incoming microcontroller data into Excel charts instantly.

is a specialized data acquisition tool that bridges microcontrollers (like Arduino or Parallax Basic Stamp) with Microsoft Excel. By treating Excel as a real-time serial monitor, it allows users to log, plot, and analyze sensor data directly within a spreadsheet. Core Features & 2021 Updates
Another software program is currently utilizing the COM port. Plx-daq Version 2.11 Download -2021-
: The direct debug window allows users to toggle logging for incoming, outgoing, or system data, and supports custom window sizing and timestamps. Expert Configs
Step-by-Step: PLX-DAQ Version 2.11 Download and Installation
PLX-DAQ 2.11 — short for Parallax Data Acquisition — collapses all five steps into . It turns Microsoft Excel into a real‑time oscilloscope + data logger, listening directly to your serial port.
You send data from an Arduino, Raspberry Pi Pico, or any microcontroller like this: Because PLX-DAQ v2
To send data to PLX-DAQ, your code must use specific prefix commands inside the Serial.println() function.

Extract the contents of the ZIP folder to a dedicated directory on your computer (e.g., C:\PLX-DAQ ). 3. Enable Excel Macros
In the PLX-DAQ panel:
Because PLX-DAQ relies on VBA macros, it can be blocked by corporate IT policies or by Windows Defender SmartScreen. If the control panel does not appear, check that macros are enabled for this particular file and that the file is saved in a trusted location (such as your Documents folder).
Under the hood, it’s still an Excel VBA macro — but a surprisingly robust one. It watches the serial port like a hawk and writes each incoming line to a new row, with optional timestamping and live graphing.
Ensure the very last variable transmission in your microcontroller loop sequence utilizes Serial.println() rather than a simple Serial.print() . To help refine your data acquisition setup, please share: What microcontroller model are you using? What type of sensors or variables are you trying to track?
