In Device Manager at Redmi 7A, Properties: “The drivers for this device have not installed. (Code 28) There are no compatible drivers for this device. To find a driver for this device, click Update Driver. ” After I activated the Update Driver button, I received the following responses: “Windows could not find drivers for your device”. Serial (port, baudrate, timeout = timeout, writeTimeout = timeout) except IOError: # FIXME with pyserial3 we might need some specific flags: self. Device = serial. Serial (port, baudrate, timeout = timeout, writeTimeout = timeout, rtscts = True, dsrdtr = True) time. Sleep (initialwait) # open returns before device is ready: self. Windows device driver information for Clear View II. The Clear View II is a type of mass storage device that is hosted on the Universal Serial Bus interface port of the host computer system. As a mass storage device it is normally deployed as a component of another equipment to provide additional storage space.

In order to assign real-time capability to a standard Ethernet port of an IPC controller, the Beckhoff real-time driver has to be installed on this port under Windows.

This can be done in several ways. One option is described here.

In the System Manager call up the TwinCAT overview of the local network interfaces via Options → Show Real Time Ethernet Compatible Devices.

This have to be called up by the Menü “TwinCAT” within the TwinCAT 3 environment:

The following dialog appears:

Interfaces listed under “Compatible devices” can be assigned a driver via the “Install” button. A driver should only be installed on compatible devices.

A Windows warning regarding the unsigned driver can be ignored.

Alternatively an EtherCAT-device can be inserted first of all as described in chapter Offline configuration creation, section “Creating the EtherCAT device” in order to view the compatible ethernet ports via its EtherCAT properties (tab “Adapter”, button “Compatible Devices…”):

TwinCAT 3: the properties of the EtherCAT device can be opened by double click on “Device .. (EtherCAT)” within the Solution Explorer under “I/O”:

After the installation the driver appears activated in the Windows overview for the network interface (Windows Start → System Properties → Network)

A correct setting of the driver could be:

In most cases an Ethernet port that is configured as an EtherCAT device will not transport general IP packets. For this reason and in cases where an EL6601 or similar devices are used it is useful to specify a fixed IP address for this port via the “Internet Protocol TCP/IP” driver setting and to disable DHCP. In this way the delay associated with the DHCP client for the Ethernet port assigning itself a default IP address in the absence of a DHCP server is avoided. A suitable address space is 192.168.x.x, for example.

lse_imu_drivers: lse_xsens_mti

Xsens MTi node. The existing xsens_mti node is distributed in the form of a library and requires the MTi to be set to a determined configuration to work. We had some old code laying around so we just ported it to ROS. This sends the MTi to configuration mode at start and sets it to the propper mode of operation.

ROS API

mti_node

mti_node is a driver for the Xsens MTi/MTi-G Inertial Measurement Unit. It publishes orientation, angular velocity, linear velocity, linear acceleration, altitude, latitude and longitude (covariances are not yet supported), and complies with the IMU API and Sensor message for NavSat API and odometry API. Take a look at the unsupported C++ API for further features.

Published Topics

imu/data (sensor_msgs/Imu)

• Streaming inertial data from the IMU.

fix (sensor_msgs/NavSatFix)

• Streaming GPS data from the IMU.

odom (nav_msgs/Odometry)

• Streaming odometry data from the IMU (linear velocity, angular velocity, orientation).

Parameters
