For detailed instructions covering how to connect to the device, see Interacting with a Sweep Device.

 

 

Visualizing Scan Data from a Connected Sensor:

 

1. Connect to the sensor and expand the "Command Controls" sub-panel.

 

2. To start collecting data, press the "START" button under the "Data Acquisition" section.

Verify that the receipt message indicates a successful start.

Note: Whenever changing motor speed (including when the device powers on), the sensor cannot start collecting data until the motor speed has stabilized and the device has performed a calibration routine. The LED on the face of the device will blink blue until the device is ready. If a start command is sent to the device when it is not ready, the device will respond indicating a failure to start scanning. If you cannot see the LED on the face of the device, you can use the "MOTOR READY" command to query whether the device is ready to start collecting data.

Note: While the device is in an active data stream, it cannot process any command but STOP. Because of this, the other device controls are disabled while the data stream is active. To change device settings such as motor speed or sample rate, first STOP data acquisition and then transmit the command.

3. To stop collecting data, press the "STOP" button under the "Data Acquisition" section.

Verify that the receipt message indicates a successful stop.

 

Visualizing Scan Data from a Pre-Recorded File:

 

1. Disconnect from any devices before opening a recording file.

2. Navigate to the "Playback" tab in the main sidebar.

3. Use the "Open Recording File" button to locate a recording file.

Recording files are .csv or .json/.scd files that contain a collection of 2D scans comprised of sensor readings in polar coordinates (azimuth + range), and a timestamp for the completed scan.

4. Once a file is open, press the play button to playback the recording in real time, or use the scrubber to quickly play through the recording.

5. Close the file by pressing the "Close Recording File" button.
