  • You might want to read about the reasons to vote down. In your case your question shows no effort of research on your issue, neither in the web nor on this site. However, you are supposed to do this before asking. (Disclaimer: I did not vote down.) Commented May 10, 2024 at 5:40

    @Juraj As a general advice, I don't agree. There are good reasons for dynamic memory allocation, even on an Arduino. It depends on the software design. Commented May 10, 2024 at 5:44

    We just looked at your question, that's it. We cannot see what you do else, and so it does not matter to us. Your post does not show any reference how you tried to solve your issue yourself and why you failed. If you think this bloats your question, well, it helps. Otherwise you'll receive irrelevant or misleading answers, which waste more of your and our time. Commented May 10, 2024 at 12:04
