•List of supported VT100 Commands
•ITM Trace via Terminal Window
The Terminal Window features VT52, VT100 protocol emulation and can communicate through standard COM ports and additionally through special debugger communication port (e.g. JTAG on ARM family) or shared target memory. This might be very useful especially since many evaluation boards already feature a serial port and the kernel of such boards usually already contains serial communication support, newer boards even include a VT100 terminal. Such boards become quickly operational using the Terminal Window.
The debugging can also become easier as the application can send messages itself to the terminal window.
To open the Terminal window select View / Workspace / Terminal.Configure the Terminal Window before use via right-clicking within the window and selecting Options from the context menu.

Status bar shows:
•The current cursor position (for example: row 1, column 1);
•Emulation type (for example: VT100);
•Connection port (for example: the COM1 serial port, with 9600 bps, 8 bit, Parity None, 1 stop bit).

Options dialog allows you to display information for easier navigation:
Serial Port configuration
The following parameters need to be configured when using the serial port:
 |
Baud Rate - Selects the baud rate the terminal is connected with.
Data Bits - Selects the number of data bits in the communication.
Parity - Selects the type of parity used.
Stop Bits - Selects the number of stop bits in the communication.
Flow Control - Selects the type of flow control used.
ITM Trace via Terminal Window
1. Select View menu / Workspace / Terminal Window. 2. Click Options button from the Terminal Window toolbar. 3. Select Debugger from the drop-down menu and click Configure. 4. Select Trace Channel as Communication Type and click Advanced. 5. Make sure that either: •All is selected in the Enabled drop-down menu or •Selected is selected in the Enabled drop-down menu and one ITM Stimuli is enabled, e.g. ITM (0) 6. Perform Debug Download. 7. Click Connect button in the Terminal Window. 8. Run the program (F5) and observe the application printing the string which is written in the core. |
