phidgets_high_speed_encoder
Driver for the Phidgets high speed encoder devices
README
Phidgets high speed encoder ROS 2 driver
This is the ROS 2 driver for Phidgets high speed encoder.
Usage
To run this driver standalone, do the following:
ros2 launch phidgets_high_speed_encoder high_speed_encoder-launch.py
Published Topics
/joint_states
(sensor_msgs/JointState
) - A joint state message containing the current state of all encoders./joint_states_chXX_decim_speed
(phidgets_msgs/EncoderDecimatedSpeed
) - One topic per encoder of the decimated (average) speed reading from the encoder.
Parameters
serial
(int) - The serial number of the phidgets high speed encoder to connect to. If -1 (the default), connects to any high speed encoder phidget that can be found.hub_port
(int) - The phidgets VINT hub port to connect to. Only used if the high speed encoder phidget is connected to a VINT hub. Defaults to 0.frame_id
(string) - The header frame ID to use when publishing the message. Defaults toencoder_link
.speed_filter_samples_len
(int) - The number of data points over which to average the speed. Defaults to 10.speed_filter_idle_iter_loops_before_reset
(int) - The number of idle loops (loops with no data) before the average speed will be reset to 0. Defaults to 1.publish_rate
(double) - How often the driver will publish data on the ROS topic. If 0 (the default), it will publish every time there is an update from the device (so at thedata_interval_ms
). If positive, it will publish the data at that rate regardless of the acquisition interval.
