Plx-daq Version 2.11 Download - -2021-

To successfully run PLX-DAQ v2.11, the following environment is recommended:

  • Hardware:

    • You send data from an Arduino, Raspberry Pi Pico, or any microcontroller like this:

    LABEL,Time,Light,Temperature
DATA,100,723,22.5
DATA,200,689,22.6

    Or even simpler:

    CLEARDATA
LABEL,Timestamp,Voltage,Current
DATA,TIME,3.45,0.12

    PLX-DAQ listens for keywords: LABEL, DATA, CLEARDATA, RESETTIMER, SLEEP. That’s it. No JSON, no MQTT, no cloud subscription.

    Released quietly in 2021, this version isn’t a rewrite — it’s a refinement of the original 2010-era macro. The update fixed:

    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.

    To this day (2026), PLX-DAQ 2.11 is still downloaded by makers who discover that sometimes the simplest tool is the right tool. Plx-daq Version 2.11 Download -2021-

    Quick start:

    Upload a simple sketch to your Arduino (see example below). Then click "Connect" in PLX-DAQ.

    1. "Compile error in hidden module"

    2. Port does not open / Access Denied

    3. Nothing appears in Excel

    4. Data clears on reset

    PLX-DAQ Version 2.11 (2021 Update) is a powerful tool designed to bridge the gap between microcontrollers and Microsoft Excel. Originally developed by Parallax and later updated by the community (notably by NetDevil), this version allows for seamless, real-time data acquisition and visualization. Key Features of Version 2.11

    Direct Excel Integration: Stream data from any microcontroller with a serial port (Arduino, Basic Stamp, etc.) directly into an Excel spreadsheet.

    Enhanced Performance: Optimized for 64-bit Excel versions and modern Windows operating systems.

    Real-Time Graphing: Use Excel’s native charting tools to visualize sensor data as it arrives.

    Interactive Control: Send commands from Excel back to your microcontroller to toggle pins or change variables.

    User-Friendly Interface: Features a simplified control panel for selecting COM ports and baud rates. Download and Installation To get started with the 2021 release of PLX-DAQ v2.11: To successfully run PLX-DAQ v2

    Download: Locate the official distribution (typically hosted on the Arduino Forum) to ensure you have the latest .zip file.

    Extract: Unzip the folder and open the included Excel macro file (.xlsm).

    Enable Macros: You must click "Enable Content" in Excel for the interface to function.

    Connect: Select your microcontroller's port, set the baud rate, and click Connect to begin logging data. Why Use PLX-DAQ?

    It is the go-to solution for hobbyists and researchers who need a lightweight, no-cost way to perform data analysis without professional-grade DAQ hardware. Whether you are monitoring temperature, pressure, or motion, PLX-DAQ transforms Excel into a robust data logger.
