Configure development computer communications with target processor
Configure communications between your development computer and the target
processor by loading and initializing a shared library that implements the
rtiostream functions.
rtw.connectivity.RtIOStreamHostCommunicator(componentArgs,
launcher, rtiostreamLib)
creates an object by using these arguments:
componentArgs ––
rtw.connectivity.ComponentArgs object.
launcher ––
rtw.connectivity.Launcher object.
rtiostreamLib ––
rtiostream shared library that implements the
development computer part of communications between the development
computer and the target processor.
The object loads and initializes the shared library.
For your development computer, Embedded Coder® provides a shared library for these communication protocols:
TCP/IP
serial
You must provide drivers for the target processors.
For other communication protocols, for example, USB, you must provide a shared library for the development computer and drivers for the target processors.
To create your instance of
rtw.connectivity.RtIOStreamHostCommunicator, you have
these options:
Instantiate
rtw.connectivity.RtIOStreamHostCommunicator
directly, providing custom arguments for the
rtiostream shared library.
Create a subclass of
rtw.connectivity.RtIOStreamHostCommunicator.
Consider this option when more complex configuration is required.
For example, when:
The subclass
rtw.connectivity.HostTCPIPCommunicator
includes additional code to determine the number of the
TCP/IP port that the executable application
serves.
You use a subclass to specify a serial port number.
You specify verbose or silent operation.
| Function | Description |
|---|---|
setTimeoutRecvSecs | hostCommunicator.setTimeoutRecvSecs(
sets the timeout value for reading data. You can configure data reading
to time out if no new data is received
for a period greater than timeout seconds. |
setInitCommsTimeout | hostCommunicator.setInitCommsTimeout(
sets the timeout value for initial setup of the communications channel.
For some target processors, you might need to set a timeout value for
initial setup of the communications channel. For example, the target
processor can take a few seconds to open its side of the communications
channel. If you set a nonzero timeout value, the communicator repeatedly
tries to open the communications channel until the timeout value is
reached. |
