Thonny doesn't really compile anything. What RFID library files are you trying to use? Are they pure Python or do they have C dependencies?

I want to use the library of MFRC522, as well as I use micropython language.

I recently intended to make a smart access control project using Stone TFT LCD, ESP32, and MFRC522.
I am using the THONNY compiler, but I found that it reports errors when adding RFID library files, which prevents me from importing RFID library files.

How to output two complementary PWM waveforms from the PICO microcontroller, by using MicroPython? pwm_A=PWM(Pin(0)) pwm_A.freq(10000000) If you use the above two lines, only one way PWM can be output, how to use the code to output two complementary PWM waveforms, one way high when the other is low....

The following code I wrote without an error being reported, but when it was executed an error occurred.

Code: Select all

>>> a = 10/0
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ZeroDivisionError: division by zero

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...

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.
