Serial Monitor window and control characters

Hello,
I need to print a value on the same position of the Serial Window again and again - like a elapsed time just at the beginning of a line without proceeding to the next line. 
The bare minimum for this to work is the functionality of the Carriage Return character '\r'. This way I could just print the value and stay in the same line. But it simply does not work with the Visual Micro Serial Monitor window.

The only functional character that is recognised is the New Line '\n' which does exactly what I don't want - placing the cursor to a new line.

Other terminal programs like HyperTerminal are working fine. How can I achieve this behaviour in the Serial Monitor?

Cheers

Hanilein

Hi,

Why do you need the \r or \n. If the separator is for your own processing why not use a pipe symbol ||

How about?

Code
Select All
Serial.print("1");
Serial.print("|2");
Serial.print("|3");


Produces 

Code
Select All
1|2|3


or

Code
Select All
Serial.print("1");
Serial.print("2");
Serial.print("3");


Produces 

Code
Select All
123




If the tool bar has "Debug" selected then Visual Micro will often wait for a \n before printing the values to the monitor. In this case after the entire packet is complete send a \n or use :-

Code
Select All
Serial.println();


note: To switch off debug, the tool bar to a different configuration that does not contain the word "Debug" or untick "tools>visual micro>automatic debugging"

Hi,

the objective is to have a screen output like a clock on a terminal that changes every second (like clocks do) without carriage return. 

My program will generate lots of output and I only want to change a small bit of that information on the screen without scrolling and re-printing the whole screen over and over again.

Cheers

Hani
