9 SOFTWARE CONFIGURATION
2. Establish the Ethernet connection. Connect LAN cable to Windows PC and integrated com-
puter. The Windows network adapter must have IP address 192.168.3.1, subnet 255.255.255.0.
The integrated computer has IP 192.168.3.11 in subnet 255.255.255.0.
3. Start Putty and in the field "Host Name (or IP address)" enter the address of the integrated
computer: 192.168.3.11. Set "Port" to 22 and "Connection Type" to SSH. Then click on "Open".
A window will open. You may be asked if this computer can be trusted.
4. Login: robot
5. Password: robot
6. After login you are in the home directory of the "robot" user, which contains the TinyCtrl direc-
tory, whose content is similar to the iRC directory in Windows.
7. Robot files are located in ~/TinyCtrl/Data/Robots/<robot type>/<robot model>/<robot model>.xml.
8. The project file where the robot file is referenced are located in ~/TinyCtrl/Data/Projects/Em-
beddedCtrl.prj
9. As editor nano, vim and vi are preinstalled.
10. After editing and saving the file, the controller must be restarted for changes to take effect.
11. To display the TinyCtrl log output live in the terminal (this is especially useful after changes in
the files), TinyCtrl must first be terminated: killall TinyCtrl
12. Then navigate to the directory ~/TinyCtrl and start ./TinyCtrl
13. The process can be terminated by pressing Ctrl+C.
14. After restarting the controller TinyCtrl starts automatically.
9.2.9 SFTP Access
The "Secure Shell File Transfer Protocol" (SFTP) access works in principle like the SSH access in the
section above, but allows the user to make changes to the project and robot files for maintenance
purposes without having to use a terminal.
Illustrated instructions are available here:

,
The Windows software iRC and the embedded control software TinyCtrl use configu-
ration files. If changes are made manually (e.g. in a text editor) to the configuration
files on one of these systems, they must also be made on the other side. Otherwise the
controllers do not behave identically, collisions may occur!
SFTP is the SSH File Transfer Protocol. It can be used to transfer or adjust files from one computer to
another. FileZilla is a free FTP program.
