Well I had a couple of days issue with implementing 2.4" 240x320 touch screen instead of 2.8" .
I was told that nothing needs to be changed and that it could work good. Unfortunately there is displacement of touch points on the screen on 2.4" so as a final result you will face problem with selecting given menus with a touch. Coordinates of menus on screen and touch points just do not match.
So there is a need to use calibration sketch so you could have proper settings for your display.
This is a situation for horizontal screen, vertical and 180 degrees rotated I do not know how to get proper calibration.
So, if PE0MGB is willing to add this sketch to it's setup and do some doc update ?

In order to proper calibrate, of tft display are:
define TFT_MISO 19
define TFT_MOSI 23
define TFT_SCLK 18
define TFT_CS 15 // Chip select control pin
define TFT_DC 2 // Data Command control pin
define TFT_RST 4
define TOUCH_CLK 18 //
define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen
define TOUCH_DIN 23 //
define TOUCH_DO 19 ///
