# DIGIT-INTERFACE
[](LICENSE)
[](https://pypi.org/project/digit-interface/)
Python interface for the [DIGIT tactile sensor](https://digit.ml).
**For updates and discussions please join the #DIGIT channel at the [www.touch-sensing.org](https://www.touch-sensing.org/) community.**
## Installation
The preferred way of installation is through PyPi:
```bash
pip install digit-interface
```
Alternatively, you can manually clone the repository and install the package using:
```bash
git clone https://github.com/facebookresearch/digit-interface.git
cd digit-interface
pip install -r requirements.txt
python setup.py install
```
If you cannot access the device by serial number on your system follow [adding DIGIT udev Rule](#adding-digit-udev-rule)
## Usage
The default connection method to the DIGIT tactile sensor is through the unique device serial number. The serial number
is found on the back of each DIGIT.
See [List all connected DIGIT's](#list-all-connected-digits) to find device serial numbers which are connected to the
host.
Once you have the device serial number, reading data from the sensor should be as easy as
```python
from digit_interface import Digit
d = Digit("D12345") # Unique serial number
d.connect()
d.show_view()
d.disconnect()
```
Upon connection each DIGIT device initializes with a default stream resolution of ```VGA: 640x480``` at ```30fps```
#### Further Usage
##### List all connected DIGIT's:
To list all connected DIGIT's and display sensor information:
```python
from digit_interface import DigitHandler
digits = DigitHandler.list_digits()
```
##### Obtain a single frame:
```python
from digit_interface import Digit
d = Digit("D12345") # Unique serial number
d.connect()
frame = d.get_frame()
```
##### List supported stream formats:
Additional streams are supported, these streams vary in resolution and frames per second.
To list the available stream formats:
```python
from digit_interface import Digit
print("Supported streams: \n {}".format(Digit.STREAMS))
```
##### Change resolution:
```
d.set_resolution(Digit.STREAMS["QVGA"])
```
##### Change FPS,
Based on supported fps for each respective resolution. All streams support pre-defined resolutions which can
be found in ```Digit.STREAMS```
```
d.set_fps(Digit.STREAMS["QVGA"]["fps"]["15fps"])
```
### Adding DIGIT udev Rule
Add your user to the ```plugdev``` group,
```
adduser username plugdev
```
Copy udev rule,
```
sudo cp ./udev/50-DIGIT.rules /lib/udev/rules.d/
```
Reload rules,
```
sudo udevadm control --reload
sudo udevadm trigger
```
Replug the DIGIT device into host.
