99% storage space used on UNO

Projects Programming
1

Dear All,

I am working on a project using an Arduino Uno. My code however uses 99% storage space and is causing stability issues. I have done my best to decrease the size of the code but I am relatively new to Arduino therefore do not know all the tricks.

Could anyone help out with decreasing the program size before I invest in a mega (which is unhandy due to size restrictions).

Thank you very much!

Apologies for the two threads, I am new to using the forum :frowning:

Thanks for the response, I made the appropriate changes yet the same issue still exists...
Is there another solution?

Thank you very much!

What everyone else said. Learn to use c strings - nul-terminated arrays of char - and the c string utilities: strcat, strcpy, atoi, etc.
