Hello Omar,
[quote user="Omar Mokhtar"]Simply, How can i interact with the target standard IO in dss like i do it in the console of code composer studio ?[/quote]
DSS doesn't quite have level of support. One alternative is to set a breakpoint where you would like to have your application wait for user input and then have the actual DSS javascript (via Java) query for user input. Then the script can take that input and write the values to the target itself (using DSS memory write APIs)
You can see this thread for some suggestions on how to get user input to the script.
