How to clear the screen in the CCS Serial Monitor

[wolfie840ca]

Hi there. Does anyone know how to send (perhaps) some escape sequences from a set of printf statements to the CCS serial port to clear the screen, set the cursor to a specific line, etc?

I believe the character you are looking for is '\f'

I tried '\f' and "\f". The screen still does not clear.

This is what I use to clear and home the cursor.

I tried the suggestion you posted. It did not work. Where did you get this information anyways?

[dyeatman]

They are Esc sequences for the VT100 terminal. Available lots of places online.
I have used these lots of times with no issues except when I omitted the delay early on.

I use these for the CCS Serial port monitor and other transmissions to serial displays.

I tried the following puts and printf which did not work:

#define ASCII_ESC 27

void clear_terminal_screen()
{
//printf("In Clear Terminal Screen\r\n");
puts( "\033[2J" );
puts( "\033[H" );
//printf( "%c[2J", ASCII_ESC );
//printf( "%c[H", ASCII_ESC );
delay_ms(500);
}

The commands ( aka escape sequences ) to control a 'screen' depend upon what the 'screen' is.
The VT100 was a common terminal made by DEC ,something like 4 decades ago....sigh. I still have a pocket card here.
Nowadays a PC can emulate a VT100, through a 'terminal program' so we'd need to know what the 'screen' is you have. Whoever is the mfr of it should have a list of commands, etc. on how to use it. If you're using a PC terminal program, it may 'emulate' a dozen of more 'screens' and some may not follow or use the VT100 'pseudo standard' escape sequences.

I am using the standard CCS Serial Input/Output Monitor that is part of their IDE. There are no options in the Configuration menu to check what terminal it emulates. I am very familiar with the VT-100 terminals from Digital. I will send CCS a ticket to the Tech Support to see if they have more infos on that topic.

Thank you all for your help.

SIOW, is not a terminal emulator program.
It is a serial 'history display' program.
It doesn't have just a window which can be cleared, it shows everything received. You can go back tens of thousands of characters by just scrolling the display back.
It's whole aim is to allow you to go back and look at what was sent to you.
Hence it doesn't have 'terminal' commands.

If you want to use terminal commands, use a terminal emulator. PuTTY, TTYEmulator etc..

Another terminal program is RealTerm. I've used it for years and has never failed me...

Ttelmah pointed out to me that "Serial Monitor is a serial 'history display' program." and not a terminal emulator. I tried using HyperTerminal and the ESC [2J escape sequence cleared the screen. Thanks a lot to everyone who tried to help me.

PROBLEM IS SOLVED.

CCSInfo tech Support told me that their Serial Monitor used to have VT-100 escape sequence capabilities but they took this functionality out. They sent me a version that has VT-100 functionality built-in and it works.

Also as many of you suggested, using Hyperterminal also works.

Thank you all.

Actually that is really silly. Though it is nice to be able to look at the 'raw' data. there really ought to be an option to enable 'terminal mode' especially if they have the basic code already written. Suggest this to them.
