Data Logging Example Project¶

This ISLoggerExample project demonstrates data logging with the InertialSense products (IMX, uAHRS, and uIMU) using the Inertial Sense SDK.

Implementation¶

Step 1: Add Includes¶

// Change these include paths to the correct paths for your project
#include "../../src/InertialSense.h"

Step 2: Instantiate InertialSense class¶

    // InertialSense class wraps communications and logging in a convenient, easy to use class
    InertialSense inertialSense(dataCallback);
    if (!inertialSense.Open(argv[1]))
    {
        std::cout << "Failed to open com port at " << argv[1] << std::endl;
    }

Step 3: Enable data logger¶

    // get log type from command line
    cISLogger::sSaveOptions options;
    options.logType = (argc < 3 ? cISLogger::LOGTYPE_DAT : cISLogger::ParseLogType(argv[2]));
    inertialSense.EnableLogger(true, "", options);

Step 4: Enable data broadcasting¶

    // broadcast the standard set of post processing messages (ins, imu, etc.)
    inertialSense.BroadcastBinaryDataRmcPreset();

    // instead of the rmc preset (real-time message controller) you can request individual messages...
    // inertialSense.BroadcastBinaryData(DID_IMU, 6); // (startupNavDtMs default)

By default, data logs will be stored in the "IS_logs" directory in the current directory.

Compile & Run (Linux/Mac)¶

Create build directory

cd InertialSenseSDK/ExampleProjects/Logger
mkdir build

Run cmake from within build directory
```
cd build
cmake ..
```
Compile using make
```
make
```
If necessary, add current user to the "dialout" group in order to read and write to the USB serial communication ports:
```
sudo usermod -a -G dialout $USER
sudo usermod -a -G plugdev $USER
(reboot computer)
```
Run executable
```
./ISLoggerExample /dev/ttyUSB0
```

Compile & Run (Windows Powershell)¶

*Note - Install CMake for Windows natively, or install the CMake for Windows extension for Visual Studio

Create build directory

cd InertialSenseSDK/ExampleProjects/Logger
mkdir build

Run cmake from within build directory
```
cd build
cmake ..
```
Compile using make
```
cmake --build .
```

Run executable

C:\InertialSenseSDK\ExampleProjects\Logger\build\Release\ISLoggerExample.exe COM3

Summary¶

This section has covered the basic functionality you need to set up and communicate with Inertial Sense products. If this doesn't cover everything you need, feel free to reach out to us on the Inertial Sense SDK GitHub repository, and we will be happy to help.
