ESP32 with TFT Display 16bit Parallel, I2C Grove Sensor, I2C Touch Control

Has anyone here managed to wire up an ESP32 with TFT LCD 3.5" display in 16 bit parallel, 12C FT touch controller and I2C Grove sensor?
It looks like (as a quick pass overview) it will all use up around 25 GPIO pins and I haven't even thought about connecting an SD Card to hold graphics data. As my application doesn't involve high-speed graphics I'll probably just revert to using the display connected as SPI but just interested in pushing the boundaries. Has anyone done it? If so would they be willing to share the pinouts used?
Regards
Charles

Ben does a very nice esp32/display board (see
https://ebay.us/m/7DqtVI )
SPI is easier if you're wiring it yourself !

Hi Martin
I beat you to it. I just ordered 3 boards this morning from RowlandTech on that ebay link. I was looking at them yesterday and when I realised they were by Ben I grabbed 3 different boards today. At least I know the quality is there rather than risk some unknown from China. I got the 16bit deluxe board as one of the three which is why i am looking into all the pin connections. Thanks for those URL links with code examples. Will probably start with those just to get a hands on feel before doing my own thing.
regards
Charles

My 16-bit display pinout and schematic is here, it needs the ESP32S3 as that has more I/O available.

Hi Charles, Hi Martin, Hi Ben
I got a board too.
I'll try using the display manager and the SD card.
That could be very useful.
