PlatformIO IDE

I am using ESP32 board, espressif 32 platform, to do my project.

But, I keep facing this SPI.h library problem which mentioned that the file has error with the variable declaration, as below.

These are the github links that I have included, but the SPI and Adafruit ButIO still showing the error, I have no idea on it…

<< platformio.ini >>

Please do not post file contents as screenshots.
Use preformatted text by enclosing the text in three backticks:

```

Libraries that you include, but which are not compatible with the ESP32 architecture or are even unnecessary:

  • GitHub - PaulStoffregen/SPI: SPI library for Teensy & Arduino IDE:
    Teensy not ESP32!

  • GitHub - arduino/ArduinoCore-avr: The Official Arduino AVR core:
    AVR not ESP32!

  • GitHub - espressif/arduino-esp32: Arduino core for the ESP32
    Totally wrong. Platform and framework is defined by platform and framework setting

On top of all the right things @sivar2311 said, try using this platformio.ini instead.

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_deps = 
  adafruit/Adafruit MPL3115A2 Library@^2.1.2
  https://github.com/avishorp/TM1637.git
  mikalhart/TinyGPSPlus@^1.0.3
  plerup/EspSoftwareSerial@^8.2.0
  adafruit/Adafruit BusIO@^1.15.0

I’ve removed all unnecessary ones, used more mainstream library for some (e.g. the direct TinyGPSPlus library instead of that old fork, or a newer version of the EspSoftwareSerial), and the PlatformIO Registry with stable versioning instead of git links (if they were registered).

Understand, I used to copy and paste all the libraries from the github, until I learned a tutorial YouTube video which guides to add the libraries by clicking the Quick Access, then click Libraries… Really appreciate the opinion and all the guidance. Thanks a lot. <3

Understand, next time will change to preformatted text instead of screenshot the images.

Ok, I will take notes on those libraries and will be careful and more focusing on deciding the libraries from github.

Thanks for the guidance <3
