Uses the v2.x ESP32 API, so doesn't compile with v3.0

[twj42]

The spec for ledcAttach has changed from v2 to v3 - functions of ledcSetup and ledcAttachPin are now merged.

even with that fixed it goes into a bootloop now

Would it be possible to get these two lines re-written for the v3.0 API?

ledcSetup(0, 10000, 8);
ledcAttachPin(38, 0);

I'm struggling translating the above into the new v3.0 API statement.

ledcAttach();

I have found this article, but I'm having a difficult time translating v2.0 to v3.0. Not a lot of information and I'm new at this.

Edit 20241022:
It seems that LilyGo / ESP Community is aware of the problem

Bodmer/TFT_eSPI#3329

I dont have the board yet.

But you can try this, starts approx on 81 :

  //set brightness
  #if ESP_ARDUINO_VERSION < ESP_ARDUINO_VERSION_VAL(3, 0, 0)
  ledcSetup(0, 10000, 8);
  ledcAttachPin(38, 0);
  ledcWrite(0, 130);
  #else
  ledcAttach(TFT_BL, 10000, 8);
  ledcWrite(TFT_BL, 130);
  #endif

Hmm ,

Been playing around with ESP libraries back and forth, but this seems to have done the trick.
Also played with #define USE_HSPI_PORT , commenting and uncomenting this. As mentioned in the issue linked here above.
But I eventually kept it commented.

Currently my weather station is operational on a V3.0.6 ESP32 library with the settings below.
I did had to manually reset the ESP32 once to get it up around, so it didn't directly start after an upload

User_Setup.h in TFT_eSPI library, eventually left #define USE_HSPI_PORT commented

// The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the default.
// If the VSPI port is in use and pins are not accessible (e.g. TTGO T-Beam)
// then uncomment the following line:
//#define USE_HSPI_PORT

Uncommented in User_Setup_Select.h in TFT_eSPI library

// S3 Display 
#include <User_Setups/Setup206_LilyGo_T_Display_S3.h>     // For the LilyGo T-Display S3 based ESP32S3 with ST7789 170 x 320 TFT

Weather.ino part

  ////set brightness
  #if ESP_ARDUINO_VERSION < ESP_ARDUINO_VERSION_VAL(3, 0, 0)
    ledcSetup(0, 10000, 8);
    ledcAttachPin(38, 0);
    ledcWrite(0, 130);
  #else
    ledcAttach(TFT_BL, 10000, 8);
    ledcWrite(TFT_BL, 130);
  #endif

You can check out my updated version , compatible with both library. atleast for me :)
Also contains brightness adjustment with the right button / button 2
