Function println(String[]) does not exist!

in Programming Questions • 2 years ago

Hello,
It's been a while that I'm using Processing & Arduino, my problem occurs when I want to use the function:
Serial.println(Serial.list());
Error: function println(String[]) does not exist!
Note: I've imported processing.serial.*;
Note: Even if i use another type of argument for println, like normal string, I see this error again, with the specified argument (function println(string) does not exist.)
How can I solve this problem??
Thanks a lot for your help...

You can find all the basic functions in the reference, such as println.

While in Arduino you might use Serial.println("SomeString"); in Processing you just use println("SomeString");

Why? You're already "on a computer" in Processing, so there is no need to "Serial". Again, just use println().

Thank you.

It worked for me :D

but there's one thing:

So processing uses Serial Port for printing by default, right?? so how can I print on that screen that is shown when I run the program? The one that is used for graphical functions/drawing?

A serial connection has nothing to do with printing text to the console in Processing. You're still looking at it from an Arduino-perspective.

You should check out the basic tutorials, especially Strings and Drawing Text. Once again, for the basic functions check out the reference. The functions are sorted by type, so the text functions are under Typography. Finally there are examples on a lot of different topics bundled with Processing. They are under File > Examples > ...
