CEmu VS circuitpython

I would need a few more zeros to motivate me to do this, but one viable approach I'll throw out there is use CEmu to validate equations. From the math side, you can start with the real equation, transform, approximate, and invert approach. For instance, for certain types of simple line drawings you can turn them into equations by: (on a real computer)

There are various cross-platform ways, I'm surprised you haven't found them (although ticalc.org probably doesn't have updated info so I guess that could explain it): TiLP (see my fork herefor Mac binaries directly) has a rom-dumping feature which produces a *full rom dump, and CEmu's dumper (which dumps less things but enough to emulate the calc, on which you can transfer missing things if needed, like apps). Since you're I retested in emulation you might want to go with CEmu (take the nightly build not the release) and follow the steps.

Unless taking screenshot via TI-Connect CE counts, you can't on a physical calculator. If you use an emulator like CEmu then it's really easy: https://github.com/CE-Programming/CEmu

The main branch of CEmu does not bring over any user data. There's a USB branch which will let you send apps and programs as if there were a USB port connected to it. You'll have to build it yourself but I'm pretty sure it's this branch: https://github.com/CE-Programming/CEmu/tree/feature/libusb

I would recommend the fx-9750giii. It's affordable. It's very interesting. And honestly, if you can find the roms for TI calculators, you can use CEmu to emulate the TI-84 CE.

For cemu the command seems to be -g , --settings Or maybe it's either. Not at my pc to test. More info here https://github.com/CE-Programming/CEmu/wiki/Command-Line-Arguments

As another point for those interested, it (to my knowledge) is currently the ONLY implementation of a scoring machine that the firmware for the device is written in Circuit Python. which gives this unit an advantage when it comes to any and all multi tasking that the unit may need to do.

The barrier to entry has never been lower. Last night I prototyped some code in Python on my Mac to talk to a Bluetooth peripheral, and then had ChatGPT translate it to Arduino C++ code for a $5 ESP32 which mostly worked on the first go.

You can even run Python on microcontrollers these days. See Adafruit's https://circuitpython.org for which they publish modules for many (almost all?) of the sensors they sell. The modern microcontroller frameworks hide much of the complexity of Wi-Fi, Bluetooth, filesystems, etc. so you can do complicated things with minimal effort. You can really cobble something together in an afternoon.

The Pico runs CircuitPython and uses Adafruit's HID library to emulate a keyboard. It's also possible to emulate a mouse and a gamepad (there are some experiments for gamepad emulation in experiments).

Asked your question in the adafruit discord and they said there's no HT1632c library for circuit python yet. There is a library for micropython. You can request to have it ported from the Micropython library I linked to by opening a feature request in the Circuit Python Github. That would be your best option for now or attempt to port the library yourself.

Microcontrollers can run Python now https://circuitpython.org/

I'm aware of two versions of Python for microcontrollers. Micro Python and Circuit Python

I tried to look in https://github.com/adafruit/circuitpython/tree/main/shared-bindings at audiocore, audioio, an audiomixer looking for a way to access the sample counter manually but I have no clue what I'm looking at :(

Try CircuitPython 8.0.3. The commit log has a couple networking changes for the Pico. My MQTT client seems to have fewer connection issues though they could be a fluke https://github.com/adafruit/circuitpython/compare/8.0.2...8.0.3
