Expand the section to find the exact COM port number assigned to your board (e.g., COM3). 3. Launch the PLX-DAQ UI Open the extracted PLX-DAQ-v2.11.xlsm file.
Version 2.11 specifically addressed bugs from earlier versions (2.09, 2.10), including improved COM port handling and reduced macro crashes during high-speed logging (up to 115200 baud).
: Ensure you have downloaded the correct 2021 Version 2.11, which includes the PtrSafe attribute fixes for 64-bit architectures. COM Port Access Denied Cause : The Arduino IDE Serial Monitor is likely open.

PLX-DAQ acts as a software serial wedge. It captures data from microcontrollers like Arduino, Basic Stamp, or PIC, and drops that data directly into an Excel sheet in real time. The 2021 version 2.11 refined this experience with improved 64-bit Windows support and UI optimizations. Key Features
Before downloading, ensure your workstation meets these minimum specifications: Windows 7, 8, 10, or 11.
To successfully run PLX-DAQ v2.11, the following environment is recommended: Expand the section to find the exact COM
Software updates don't always mean improvement. Many users report that recent forks of PLX-DAQ crash when handling large datasets. Version 2.11 is the "Toyota Hilux" of this software—it’s ugly, but it never dies.
To log data from an Arduino to Excel, you must use specific serial commands that the PLX-DAQ macro can interpret.
: Automatically scrolls the Excel sheet as new data rows are added (available for Office 2013+). Improved Debugging Version 2
The update from 2021 remains the most reliable, free way to log data from Arduino into Excel on modern computers. By bridging the gap between hardware sensors and robust data analysis software, it provides an invaluable tool for hobbyists and professionals alike.
: Select your microcontroller's port, set the baud rate, and click Connect to begin logging data. Why Use PLX-DAQ?
