Compiling issue

[Firephinix]

I'm having trouble compiling the code.
I'm a newb to coding and generally us chatGPT for codes which so far has worked for my projects but this doesn't seem to want to compile.
Compilation error: 'ledcSetup' was not declared in this scope

I'm using this board https://www.amazon.co.uk/dp/B0BGY69RCK?psc=1&ref=ppx_yo2ov_dt_b_product_details which I think is pretty much the same as the TTGO.

I've tried selecting different boards but still the same error

Please help as I have no idea!

Use the espressif board manager for the TTGO t_display. However, you must install versions 2.17. The 3.x versions do not work. I'm working on a fix for this. The ledcSetup is easy to fix, but the 3.x versions break the TFT_eSPI display library and I don't have a fix for that yet.
