The ScientISST SENSE Python API.

Learn how to use it, check examples, and much more here!

Installing

# Getting this repository 
git clone https://github.com/scientisst/scientisst-sense-api-python.git

Dependencies

Dependencies are specified in the requirements.txt file.

Install them using pip:

pip install -r requirements.txt

Using Docker in Linux

When running the API on Linux, if issues arise, it is recommended to try using it inside a docker container.

First, install docker.

Then, clone the repository and navigate to the directory:

# Getting this repository 
git clone https://github.com/scientisst/scientisst-sense-api-python.git
cd scientisst-sense-api-python

Then, build the docker container with:

sudo docker build -t sense_docker .

It is required to build the container only once. Finally, run the container with:

sudo docker run -v /var/run/dbus/:/var/run/dbus/:z --privileged -it sense_docker

This will open a terminal inside the container with access to bluetooth and Wi-Fi. To exit the container run:

exit

Running

Automatic

1. Pair your device
2. Run:

python sense.py

3. Select the device from the list displayed:

ScientISST devices:
[1] ScientISST-ab-de - 08:3A:F2:49:AB:DE
[2] ScientISST-ac-be - 08:3A:F2:49:AC:BE
Connect to: 

4. Hit CTRL-C when you wish to stop.

Help

$ python sense.py -h

usage: sense.py [args] address

description: The program connects to the ScientISST Sense device and starts an acquisition, providing the option to store the received data in a .csv file.

positional arguments:  address               Linux: bluetooth MAC address, Mac: serial port address, Windows: bluetooth serial COM port

optional arguments:
  -h, --help            show this help message and exit
  -f FS, --frequency FS
                        sampling frequency, default: 1000
  -c CHANNELS, --channels CHANNELS
                        analog channels, default: 1,2,3,4,5,6
  -d DURATION, --duration DURATION
                        duration in seconds, default: unlimited
  -o OUTPUT, --output OUTPUT
                        write report to output file, default: None
  -s, --lsl             stream data using Lab Streaming Layer protocol
  -q, --quiet           don't print ScientISST frames
  -v, --verbose         log sent/received bytes

Manual

Linux

Pair and trust the ScientISST Sense board:

bluetoothctl
scan on
pair XX:XX:XX:XX:XX
trust XX:XX:XX:XX:XX

You can now run the sense.py script:

python sense.py XX:XX:XX:XX:XX

Mac

First, you need to pair the ScientISST sense device in the Bluetooth Settings section. Then, you'll need to find the serial port address using the Terminal:

ls /dev/tty.ScientISST*

Copy the String like: /dev/tty.ScientISST-XX-XX-SPP_SE.

You can now run the sense.py script:

python sense.py /dev/tty.ScientISST-XX-XX-SPP_SE

Windows

Turn the ScientISST Sense board on.

Now, go to Control Panel > Hardware and Sound > Devices and Printers. Select "Add a device". Select the ScientISST Sense board, hit "next" until its set up.

While connected to the board, search "Bluetooth settings" on the Control Panel, then go to the "COM ports" tab and check the port name for the outgoing entry. Copy the String like: COMX

You can now run the sense.py script:

python sense.py COMX

Example

Example usage to acquire AI1 at 10Hz sample rate (Linux):

python3 sense.py -f 10 -c 1 -o output.csv 08:3A:F2:49:AC:D2

Plot

Dependencies:

• pandas
• numpy
• matplotlib

python plot_output.py
