Global array size limit

If I create a global variable array, the size does not get included in the build details and if I select a size that is bigger than available RAM, I do not get an error. For example "int x[100000]" does not produce an error in the KL05Z. If I refer to x[99999] in my code, then I get an out of space error. How do I know how much RAM I have used? I realize that any non-static variable declared inside a function will be carved out of the stack, but I would think any global variable should reduce the RAM used in the build details.

Thanks, Tom

Are you actually doing anything with those arrays? Otherwise they get optimized out by the compiler.

Accepted Answer

You are right. I had not yet written the code to use the array.

Thanks, Tom
