serial monitor: empty line after each text line

Print Post  
Hello,

I don´t know why but since some time (maybe last update ?) after each text line i get an empty line in the serial monitor.

I didn´t change the code.
I checked it with the Arduino IDE serial monitor and there it is ok.

I tried difference settings but nothing change it.

As attached a pic of the VS serial monitor with the empty lines and a pic from the Arduino IDE serial monitor.

How can i fix it?

Visual Micro V2026.422.2201

Thanks for the report.

Could you attach the build output with the below options enabled, and a quick example or excerpt from your sketch around the print statements?
  • vMicro > Compiler > Verbose
  • vMicro > Compiler > Show Build Properties


This is just to ensure we replicate the issue fully so we can provide the fix ASAP.

Hello,
as attached the micro build output.

The print statements are very easy:
Code (C++)
Select All
Serial.printf("cw: infotext - no: %s, text: %s\n", controldata.number, controldata.text);


\n is neccessary to get a new line with printf

But it happens also with println
Code (C++)
Select All
Serial.println(F("----------------------------------"));

Thanks for the information and files.

This is related to the Serial Debugger being enabled, which we will resolve as soon as possible.

If it is not in use it can be disabled by changing the  Build configuration to Release.

Ill update when the fix is available.

This is shown on the below page:
https://www.visualmicro.com/page/User-Guide.aspx?doc=Build-Configurations.html

Currently it is a box at the top of your VS Toolbars which will show "Debug", change it to "Release" and then build and upload again.
