The IDE prints a message about sketch size and memory usage |
4405339237522 |
The IDE always checks for storage space and dynamic memory usage when compiling your code, and then prints the results to the console. For example:
Sketch uses 4316 bytes (15%) of program storage space. Maximum is 28672 bytes.
Global variables use 153 bytes (5%) of dynamic memory, leaving 2407 bytes for local variables. Maximum is 2560 bytes.
-
In this case, both values are below 100% and you don't need to do anything.
-
But, if either storage space or dynamic memory usage is above 100%, you have to free up storage space or optimize your code. See Reduce the size and memory usage of your sketch for more information.
