Compilation error: 'ledcSetup' was not declared in this scope

I wonder if this is a simple user error issue.... trying to compile this and get the following errors. I think I have the board and framework all setup correctly. Using ArduinoIDE

/Users/anthonyjclarke/Downloads/ResistorTTGO/ResistorTTGO/ResistorTTGO.ino: In function 'void setup()':
/Users/anthonyjclarke/Downloads/ResistorTTGO/ResistorTTGO/ResistorTTGO.ino:36:3: error: 'ledcSetup' was not declared in this scope
36 | ledcSetup(pwmLedChannelTFT, pwmFreq, pwmResolution);
| ^~~~~~~~~
/Users/anthonyjclarke/Downloads/ResistorTTGO/ResistorTTGO/ResistorTTGO.ino:37:3: error: 'ledcAttachPin' was not declared in this scope; did you mean 'ledcAttach'?
37 | ledcAttachPin(TFT_BL, pwmLedChannelTFT);
| ^~~~~~~~~~~~~
| ledcAttach

exit status 1

Compilation error: 'ledcSetup' was not declared in this scope

Many thanks in advance

I think the issue is resolved, documenting if others have this... thanks to this thread.... https://forum.arduino.cc/t/how-to-display-image-on-ttgo-t-display-esp32/1174923

ledcSetup(pwmLedChannelTFT, pwmFreq, pwmResolution);
ledcAttachPin(TFT_BL, pwmLedChannelTFT);
ledcWrite(pwmLedChannelTFT, 100);

just comment out these three lines for the code to work properly
