Request: ESP32 Devkit with custom display / input

[shvelo]

Hello, I would love to have an option to extend the S3-Devkit platform with display and input support with custom pin definitions to be able to use it on a breadboard.
I know there is a way to replicate one of the supported targets with display on the breadboard, but it requires some digging.
My proposal is to have another platform in platformio.ini based on S3-Devkit which allows configuring display and input via build flags, maybe using the LovyanGFX library from t-display-s3.
I'd try to implement this myself but I'm not very good at this yet.

It will be easier to start from the T-Embed than from the T-Display.
The T-Display has a screen with a parallel interface which is less common, on the market places, than the one of the T-Embed which has an SPI interface.
The T-Display has only 2 buttons and it is really a pain to enter the password for accessing WIFi. The T-Embed is using a rotary encoder wich makes it easier.
That said, a T-Display board costs around €15 on AliExpress (without a case) and €25 with one. It has a large number of I/O pins accessible from the back. Considering the price of the components and the time spent customizing the DevKit, buying a T-Display is, in my opinion, a good deal.

Concerning your proposal, if we add a new environment for a DevKit with a display it will open the door to hundreds of requests from people who want a different screen or the addition of this or that option. It will be a nightmare to manage it. It is my 2 cents, iI is @geo-tp who sets the main directions in development.

This is now possible through the new custom environment (see platformio.ini)

Instead of adding a dedicated environment for every possible DevKit + display combination, there is now a generic custom target that can be configured directly from platformio.ini using build flags
