| May 4, 2016 at 13:44 | comment | added | David Cary | If you want to learn a lot of details about the 1975 Data Encryption Standard (DES), implementing it from scratch will teach you a lot. However, if your goal is to actually encrypt something, perhaps it would be better to (a) use a more modern cipher such as Twofish or AES; or (b) use a pre-existing library; or both. See Spaniakos, AESLib, AES-library, etc. | |

About the Serial and LiquidCrystal: Yeah, I forgot about it. Thank you for pointing about, but I am afraid not even this solves the riddle.

You are also using the LiquidCrystal library and Serial (which uses a 64 byte buffer). Removing all else, you end up with about 260 bytes already. Though, I have no idea where the other 750 bytes go to.

| Feb 10, 2016 at 19:30 | comment | added | SlowerPhoton | On what kind of file should I call it? All I have are .ino files. And it doesn't take my project file as an argument. It tells me it 'is not an ordinary file'. | |

What does avr-nm -Crtd --size-sort your_elf_file tell you? Look at symbols of type D, B and V.
