DIGIT-Setup is a minimal Python script for initialising, testing, and streaming data from a single DIGIT tactile sensor using the digit-interface library.
This tool provides a quick way to:
- Connect and configure a DIGIT sensor
- View a live stream of tactile data
- Save example frames as image files
- Print basic sensor information
- Operating System: Linux only (DIGIT sensors are supported on Linux only)
- Tested Environment: Ubuntu 22.04, Python 3.13.5
- Python Environment: Regular Python or Anaconda environment
- Packages: digit-interface
git clone https://github.com/gemixin/digit-setup.git
cd digit-setup-
(Optional) Set up a virtual environment:
python3 -m venv venv source venv/bin/activate -
Install the required package:
pip install digit-interface
Create a new conda environment using the provided environment.yml:
conda env create -f environment.yml
conda activate digit-env- Connect your DIGIT sensor via USB.
- Run the script:
python single_digit.pyThe script will:
- Automatically connect to the DIGIT sensor
- Display configuration info
- Stream a live tactile view
- Save a few frames locally as
.jpgimages
Follow the terminal output for step-by-step feedback.
- VGA Mode Bug:
The digit-interface library has a known issue with VGA mode producing glitchy output.
See issue #10.
✅ Recommendation: Stick to QVGA mode for reliable operation.
