RMT driver and fastpin issues

[RobPackerAU]

Hi Damian,
I am new to FastLED and am trying to get it working with an Adafruit ESP32-S3 and found your project. I used your main.ino file and got a series of errors.
My setup is ArduinoIDE 2.3.2 on a Windows 11 system.

The repeated errors are:
d:\Data\Arduino\libraries\FastLED\src\fastpin.h:296:16: warning: 'volatile'-qualified return type is deprecated [-Wvolatile]
and
C:\Users\rob\AppData\Local\Arduino15\packages\esp32\tools\esp32-arduino-libs\idf-release_v5.1-442a798083\esp32s3/include/driver/deprecated/driver/rmt.h:18:2: warning: #warning "The legacy RMT driver is deprecated, please use driver/rmt_tx.h and/or driver/rmt_rx.h" [-Wcpp]
18 | #warning "The legacy RMT driver is deprecated, please use driver/rmt_tx.h and/or driver/rmt_rx.h"
| ^~~~~~~

I am hoping you might be able to help solve this. The whole of the output is in the attached text file.
