toolchain VS rofi-calc

Download: https://github.com/CE-Programming/toolchain/releases/latest

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.)

calculator

I would assume that they just mean rofi which is an app launcher that can be configured to do a lot more than just that. It can work as an emoji picker, calculator, and other general menus

I found this tool https://github.com/svenstaro/rofi-calc which add live calculation in rofi, but i cannot get it to work. Could anyone help?

Do you use rofi? Have you looked at rofi-calc? While it doesn't have a blocks widget, if you're not comfortable with a key binding and you're using a block bar that supports mouse click modules (like i3status-rust, or others) you can add a block that spawns rofi-calc on click.
