Changing Environment Properties with Command
Line Interface
xPC Target lets you define and change different properties. These properties
include, the path to the C/C++ compiler, the host COM-port, the logging buffer
size, and many others. Collectively these properties are known as the xPC
Target environment.
You can use the command line functions to write an M-file script that accesses
the environment settings according to your own needs. For example, you could
write an M-file that switches between two targets.
The following procedure shows how to change the COM port property for your
host PC from COM1 to COM2:
1 In the MATLAB window, type
setxpcenv(’RS232HostPort’,’COM2’)
The up-to-date column shows the values that you have changed, but have
not updated.
Making changes using the function
setxpcenv does not change the current
values until you enter the update command.
2 In the MATLAB window, type
updatexpcenv
The environment properties you changed with the function setxpcenv
become the current values.
