Chinese TFT SPI 2.8'' display as touchscreen

I can understand someone being good or bad at programming.

I can't understand one photo without i.c. and another photo with an i.c.

Use voltage dividers. I suggest that you post your schematic. Pencil drawing is fine.

There are many libraries: e.g. Adafruit_ILI9341.h, SD.h, XPT2046_Touchscreen.h
