Terminal escape sequences

Hi there,

I try to use the escape sequence "\r" in the terminal to move the cursor to the begin of the current line. This does't work. CStr is active. According to the release notes this should word.

What I'm doing wrong?

My example code:

Code (C++)
Select All
void setup()
{
  Serial.begin(9600);
  delay(1000);
}

long test = 0;

void loop()
{
  test++;
  Serial.print(test);
  Serial.print("\r");
  delay(1000);
}


Sorry: I'm using Visual Studio 2015 and VMICRO, both in the most current version. I try it on an Arduino nano...

Thanks in advance!

Regards from Germany

Alex  Smiley

Hi

The "terminal" works the same way as the arduino ide in as much as it is a forward only output.

Your code should cause a new line after the test data, therefore the next print will be on the next line.

Notes ...

Generally \n is better than a single \r or \r\n. Normally you can simply use println() instead of print

Serial.println(test);

or

Serial.print(test);
Serial.println();

or

Serial.print(test);
Serial.print("\r\n");

or

Serial.print(test);
Serial.print("\n");

Hi,

that the \r in the Arduino IDE is not working is a known bug that will be fixed in the future (this info can be found in the Arduino forum).

Many people use e.g. putty to get a correct working terminal. But this is very circumstantial. I had the hope, that a third party product will work as expected and do not copy the neglects of the original Arduino IDE.  Wink

Hi,

It's not a neglect for people who just want a new line. println() is best.

There have been some requests for some additional terminal options so they are certainly on the list.

Thanks

btw: cstr stuff relates to outbound from pc to arduino only.
