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?

Connects up to 15 COM ports simultaneously.

Although version 2.11 was designed to support 64‑bit Office, some users have reported that it works best with and may be less stable on very recent versions of Office 365. That said, many reports confirm that it does work correctly on Office 365 as well. If you encounter problems, try running Excel with administrator privileges, or ensure that no other software is using the same COM port (e.g., close the Arduino Serial Monitor).

PLX-DAQ is an open-source software add-in for Microsoft Excel. It acts as a software bridge, allowing microcontrollers to send text commands over a standard USB/Serial (COM) port. Excel interprets these commands in real-time, automatically filling cells, creating rows, and charting data as it arrives.

void setup() Serial.begin(9600); // Match baud rate in PLX-DAQ Serial.println("CLEARDATA"); // Clears previous data on connect Serial.println("LABEL,Time,Sensor Value,Voltage"); // Column headers

Version 2.11 represents a pivotal update for the software. The original PLX-DAQ (v1.x and v2.0) began failing as Microsoft updated Excel security protocols and 64-bit systems became standard. (If the direct link does not work, visit
