Project description
BlinkStick Python interface to control devices connected to the computer.
What is BlinkStick? Check it out here:
Requirements
Python
PyUSB
grapefruit - package for color manipulations
pyusb - package to access USB devices
psutil - only for example-cpu.py
websocket-client - only for example-connect.py to connect to BlinkStick.com
Installation
Install all required packages with pip:
[sudo] pip install blinkstick
If you would like to run the example scripts, you may also need to install the extra dependencies
[sudo] pip install psutil websocket-client
If websocket-client fails to install, please make sure you run the following command:
sudo apt-get install python-dev
Replace python-dev with python2.7-dev if you are installing on Raspberry Pi.
Description
Description of files:
blinkstick.py - main BlinkStick class definition
example-info.py - displays information of each BlinkStick
example-infoblock.py - read/write info block sample
example-off.py - turn all blinksticks off
example-random.py - set random color to all BlinkSticks
example-cpu.py - displays CPU usage with a BlinkStick (transitions from green as 0% to red as 100%)
example-connect.py - sample code to connect to BlinkStick.com and control it remotely
Running examples:
python example-info.py
Permission problems
If the script returns with an error
Access denied (insufficient permissions)
You can either run the script with sudo, for example:
sudo python example-info.py
Or you can add a udev rule to allow any user to access the device without root permissions with this single command:
echo "SUBSYSTEM==\"usb\", ATTR{idVendor}==\"20a0\", ATTR{idProduct}==\"41e5\", MODE:=\"0666\"" | sudo tee /etc/udev/rules.d/85-blinkstick.rules
Reboot computer after you have added the command and all users will have permissions to access the device without the need of root permissions.
