Targets

Configure and manage target objects

Since R2020b

Description

A Targets object represents Speedgoat^® target computers that are defined on the MATLAB^® development computer and provides access to methods related to the target computers.

Creation

targets_object = slrealtime.Targets() constructs a Targets object representing target computers that are connected to the development computer.

Example: Create Targets Object, Add Target Computers, Set IP Address

Object Functions

addTarget	Add target computer definition to targets object
removeTarget	Remove target computer definition from targets object
getTargetSettings	Get target computer environment settings
getDefaultTargetName	Get default target computer name
setDefaultTargetName	Set default target computer name

Examples

Create Targets Object, Add Target Computers, Set IP Address

To work with multiple target computers, make the computer names available by using a targets object.

1. Create targets object my_tgs. Add target computers to the targets object. Assign target computers to target objects. Create a target settings object and list the target computer names.

   my_tgs = slrealtime.Targets();
   % do not need to add default target 'TargetPC1'
   addTarget(my_tgs,'TargetPC2');
   addTarget(my_tgs,'TargetPC3');
   
   % assign target computers to target objects
   tg1 = slrealtime('TargetPC1');
   tg2 = slrealtime('TargetPC2');
   tg3 = slrealtime('TargetPC3');
   
   % list target computer names
   my_tgs_settings = getTargetSettings(my_tgs);
   my_tgs_settings.name

   ans =
   
       'TargetPC1'
   
   
   ans =
   
       'TargetPC2'

2. Set Target object tg1 IP address to '192.168.7.5' by using the TargetSettings property.

   tg1.TargetSettings.address = '192.168.7.5';
   tg1.TargetSettings;

   To set the IP address on the target computer, use the setipaddr function.

Change Password for Target Computer

For security, some installations require changing the default userPassword for the target computer. To customize the password, change both:

— The userPassword in the TargetSettings

— The password for the slrt user on the corresponding target computer

1. Create targets object my_tgs. Add target computers to the targets object. Assign target computers to target objects. Create a target settings object and list the target computer names.

   my_tgs = slrealtime.Targets();
   % do not need to add default target 'TargetPC1'
   addTarget(my_tgs,'TargetPC2');
   addTarget(my_tgs,'TargetPC3');
   
   % assign target computers to target objects
   tg1 = slrealtime('TargetPC1');
   tg2 = slrealtime('TargetPC2');
   tg3 = slrealtime('TargetPC3');
   
   % list target computer names
   my_tgs_settings = getTargetSettings(my_tgs);
   my_tgs_settings.name

   ans =
   
       'TargetPC1'
   
   
   ans =
   
       'TargetPC2'

2. Set Target object tg1 userPassword to 'H3lloThere!' by using the TargetSettings property.

   tg1.TargetSettings.userPassword = 'H3lloThere!';
   tg1.TargetSettings;

   To set the password on the target computer, open a PuTTY session to the target computer (log in as user root and password root) and use the passwd command to set the password for the slrt. For more information about using PuTTY, see Execute Target Computer RTOS Commands at Target Computer Command Line.
