Blink(1) ROS node
What is this repository for?
This node provides a ROS service and a ROS topic that manipulates Blink(1). Accompanies the node a service API that facilitates the use of the service. This API is not ideal for real time use. For real time, use the topic version.
How do I get set up?
The code depends on libUSB. To install libUSB:
#!bash sudo apt-get install libusb-dev
To install the Blink1 package:
Create a catkin workspace. For instructions on how to create the workspace go here. Download and compile the package:
#!bash cd catkin_ws/src git clone firstname.lastname@example.org:castacks/blink1_node.git cd .. catkin_make
To run and test the node you must have permission to access the Blink(1) device. For a first test you may change to root (
sudo -s) and run:
#!bash source devel/setup.bash roslaunch blink1 blink1.launch
In another terminal:
#!bash source devel/setup.bash rosrun blink1 blink1_example
#!bash source devel/setup.bash rosrun blink1 blink1_example_topic
The led should turn on and blink with several colors. See the examples folder to the code of these examples.
To permanently change the permissions of the device and run the node in the user mode, please refer to the instructions of the device's manufacturer.
