toolchain VS wabbitemu

if you're talking about the CE series of calculators, then people have been, and still are, creating lots of programs using the community toolchain, and despite the fact that the architecture is eZ80, a clang-based compiler has been developed (llvm backend) and so C and C++ is available.

If you're talking about the TI-84 Plus CE, you can create powerful programs in C (and some C++) with the community toolchain.

The C toolchain can help you with that: https://github.com/CE-Programming/toolchain/releases/tag/v10.2 You may need to get one of the USB branches.

I'm working on a library called srldrvce for using USB serial adapters with the CE. Unfortunately, it's not released yet, but you can build it from source from the srldrvce-rewrite branch of the C toolchain. In theory, there are supposed to be nightly builds as well, but we changed our CI system recently and I can't find them at the moment. You might also find my terminal emulator for the CE helpful.

If you're wondering why they put an ARM microcontroller in there to run Python, the answer is that the TI-84 Plus CE uses an eZ80 CPU core because it made transitioning their existing TI-84 Plus code a lot easier. The downside is that they don't have access to a C compiler than can compile Python (but we've written one), so they hacked in a microcontroller to run MicroPython.

The TI-84 Plus CE doesn't have anywhere near the library that the TI-83/84 Plus has, but our community SDK supports all the features of C and C++ that clang does (no STL support). Development has largely shifted to the CE. As someone who's written a fair amount of Z80 assembly, I can tell you that C is amazing.

Check out the community toolchain and its documentation.

If you want to learn assembly you can either do it standalone using this tutorial or as part of the C toolchain.

It seems you can write C/C++ programs for the Ti-84 with this. (In theory you can write / run C/C++ programs on anything which can run Turing-complete programming language.)

Yes, I use the wabbitemu emulator to test the code locally. The most important thing about that is that I don't have to remove the batteries to reset the calculator if I have an error that bricks it. I have dumped the rom from my own calculator though, so given that the emulator is accurate, I should be observing the exact same behaviour as on my physical calculator.

theres wabbitemu http://wabbitemu.org/

When I was in school we used wabbitemu as a literal TI-84 emulator. Just download the official ROM from TI’s website lmao.

Years ago when I used Wabbitemu it downloaded a "ROM" from the official website, so it was(maybe) legal to use, but not copy (due to copyright restrictions). At some point TI took action to block those downloads and I haven't used TI since before then, so I'm not sure what they do now.
