Synchronizing Multiple USB NI Data Acquisition Devices using ANSI C and NI-DAQmx

This project provides a Visual Studio solution for synchronizing and acquiring data from multiple USB National Instruments (NI) Data Acquisition (DAQ) devices using ANSI C and the NI-DAQmx driver. The solution includes code for synchronizing two USB-DAQ devices, each equipped with 8 analog input channels. The acquired data from all 16 analog input channels is saved to a file for further analysis.

Features

• Synchronizes data acquisition between two USB NI DAQ devices
• Acquires data from 16 analog input channels (8 channels per device)
• Saves the acquired data to a file for subsequent analysis

Requirements

• Two USB NI DAQ devices (compatible all ni-usb DAQ models)
• Visual Studio (tested with [2015])
• NI-DAQmx driver software

Usage

1. Connect both USB NI DAQ devices to your computer.
2. Install the NI-DAQmx driver software (download link) if it is not already installed.
3. Open the Visual Studio solution provided.
4. Build the solution to generate the executable.
5. Run the executable.
6. The program will synchronize the two devices and initiate data acquisition from all 16 analog input channels.
7. The acquired data will be saved to a specified file format (e.g., CSV, TXT) for further analysis.

Device Compatibility

This code has been tested with the following USB NI DAQ devices:

• Two : USB-6001
• Two : USB-6008

Note: The code can be adapted to work with other USB NI DAQ devices by modifying the device-specific configurations and settings.
