ESP32 code coded into micropython

I saw a weather station project done online using ESP microcontroller and TFT LCD , but he was using Arduino to program ESP32, I now want to port it to Raspberry Pi, but the code of ESP32 is not very comprehensive given. Here is the code as far as I can see. https://www.stoneitech.com/media/upload/s...

Re: I/O capable GUI

Is this using the MCU for interface design, or does it have its own GUI design software?

What puzzles me is that fingerprint sensors seem to be cheaper than touchscreens.
Yes, but the touch screen is what I already have I don't need to buy separately, the fingerprint sensor I need to buy additionally, but now it seems to be the only way to buy a fingerprint sensor.

For example, if an invisible button is added to the place where the finger is placed, it looks like the fingerprint is unlocked from the outside, but...

Re: Fingerprint unlocking electronic lock based on ESP8266

I wanted to find a way to replace this recognition and make it "fingerprint recognition" with something else. Sorry not quite sure what you're asking? Do you have a suggestion for what "something else" might be... a touchscreen isn't going to be able to read a fingerprint, but you could, for exampl...
