[openrtm-users 01405] Re: Regarding FSM component in OpenRTM

[Geoffrey Biggs]

Hi Tony,

There is documentation about the examples on our new website, but that
isn't live yet. The examples are roughly as follows:

SimpleIO: Demonstrates basic component and data port operations, as well
as more complex functionality such as data port callbacks. One component
reads a number from the terminal and sends it over a data port; the
other receives a number on its data port and prints it to the console.

SeqIO: Similar to SimpleIO, but demonstrates the use of sequence data types.

SimpleService: Demonstrates using a service port. Unlike a data port, a
service port is a two-way RPC-based communication. Use it to provide
services requiring a synchronised response.

ConfigSample: Demonstrates the use of configuration parameters and
configuration sets. While running, this component will constantly print
out its current configuration. You can alter individual parameters of
this configuration or change the active set at run time using
RTSystemEditor or the rtconf command from rtcshell.

Composite: Demonstrates a composite component. A composite component is
one component who's behaviour is made up of multiple child components.
This example also demonstrates several features of the manager, such as
pre-loading component implementation libraries and automatically
creating components when the manager is started.

If you are using the Windows version, you will also have other samples
such as an image acquisition component and an image display component,
using OpenCV.

Don't forget that you can also find other components on our website in
the "Components" section. The new website will have a much larger
number. Many of these components use more complex data types such as
those defined in the ExtendedDataTypes.idl and InterfaceDataTypes.idl files.
