Split a string as 2x16 for LCD

Question

How do I split a string into two based on it's length to display on a 2x16 LCD?

I have seen a function called length() to get the length of a string. But, any ideas how to split it in to 2x16 and trim the rest of the string?

Thanks

Answer 1

String::Substring does take a start and an end value. So you can do something like this:

String s1 = longtext.substring(0,15);
String s2 = longtext.substring(16,31);

Answer 2

That's what String::substring() is for. Simply take the first 16 characters and the characters from 16 to 32, and output them.

• Josh: But,what about the rest of the string? I need 2 x 16 of the 32. Substring only provides one part right?
• Ignacio Vazquez-Abrams: Use it as many times as you need in order to get all desired substrings.
