Debugging your application

Once your application has been successfully built, access the Debug context from the

STVD main menu to access the debugging features that are supported by your debugging

instrument. The debug instrument must be selected before starting debugging.

Select Debug Instrument > Target settings from the STVD main menu toolbar.

Select Swim ST-LINK, which is your debug instrument (see Figure 23).

Click Apply to confirm and OK to close the window.

Select Debug > Start Debugging to start your debug session and access the debug

context. STVD then connects to your debug instrument, loads the code into the

microcontroller Flash memory, and provides access to the debug commands and

menus. You can now start debugging your application (see Figure 43).

Figure 43.

Debugging your application

Several debug windows are available in STVD. You can access them by selecting View

menu when a debug session is ongoing.

One of the most useful windows is the Peripheral registers window. It can be used to

display the content of the STM8L105C6 peripheral registers during the debug session. (see

Figure 44).

The Watch window displays the values the code variables. Just drag and drop a variable

from your code into the Watch window.

The information displayed in the debug windows are refreshed when the program is stopped

(for example by a break point). (see Figure 45)
