compilations errors ( ESP32 CORE issues / 'ledcAttach' was not declared in this scope)

[NashMerwolf]

Hi, trying to update my project to your TTGO version . there was alot of problems while compiling with lines :

86 //ledcSetup(ledChannel, freq, resolution);

89 //ledcAttachPin(tftEnable, ledChannel); that i commented to check back problems.

i hit on this problem concerning ESP32 library :

Figured out that it was ESP32 core 3.0.4 wasnt supported. i tried with 2.0.14v and compiled well with lines #89 - 88 - 86 commented//

Work too with 2.0.17 but not 3.0.0
