Hello, everyone! I have an HP Prime G2 calculator, and I’m thinking about upgrading it. My idea is to integrate it with an Arduino ESP32-S3 (with Wi-Fi), allowing them to communicate in a chat-like manner. The calculator would send its input to the Arduino, which would make a request to the ChatGPT API and return the response directly to the calculator. Has anyone tried something similar or have any tips on how to get started with this project?
I assume the calculator has some way of connecting to the Arduino, if so, look at the sample sketches for the ESP32-S3 to do with WiFi.
The second issue is a bit more problematic, what kind of data will the calculator write and read to the esp32? binary, ascii, something else?
I have a feeling you already have the answer right at your fingertips; your cell phone with its handy web browser might be all you need!
