#ARDUINO PRINTLN ERROR STRING CODE#

As its name suggests this is like a single stack of coins. Local variables in functions are placed on the stack.

Each one represents a variable in your program. So let’s describe the stack and the heap so you can grasp the difference. The main part we are concerned with here is the heap. If you want to know more about how these chunks of memory relate to each other you can read more on Wikipedia here: There’s the stack where local variables created within function are stored, and finally there’s the heap, which is where dynamic variables are stored (more on those in a moment). There’s a chunk where all the global and static variables are stored (aka BSS and data areas). The Arduino’s RAM is split up into different chunks for different purposes. First a little bit of computer theory – especially to do with memory. So I’m here to tell you firstly why you shouldn’t use String objects, and secondly, if you really must use them, how you go about using them properly. However, if you don’t know what you’re doing when it comes to low level C++ programming then it is very easy to abuse the String object in such a way that it makes everything about your sketch fragile and unstable. The String object was created to make working with blocks of text easier for people that don’t really know what they are doing when it comes to low level C++ programming. Strings are a bit of a tricky area on the Arduino.

Well, you should forget all you think you have learned about using Strings on the Arduino, because it is all wrong.

Due to WordPress’s abysmal handling of code blocks this blog post is now hosted at Įveryone, when they’re starting out on the Arduino and similar boards, learns to use the String object for working with text.
