Usage

Usage: fx-meta [filename]
Prints out metadata of a CASIO fx-9860G file.

Example output with my PONG port:

Build

All you need is make, gcc and pkg-config. Download this repo (either through git or as a zip/tgz) and run make.

The binary should be in bin/fx-meta.

Why

I've made it because I'm currently learning C (for uni) and I think dipping my feet into the water is a great way to get started.

Just for now, I can see a few issues with it. Everything is in the main method, it's targeted towards the GCC compiler (because that's what I have on my Linux machine, and endianness is a thing), strings from the headers are not null-terminated (look for the // nt comment).

If you have any solutions to these problems (that can be properly comprehended by a complete C/C++ newbie) that would be amazing.
