you must give still more detailed description of the requirement.

-what is 'convert transfer a hex file'?
-is the hex file is for nextion?
-a push button input to be transferred to touch screen?

the hex is in the pic 16f84a or 16f628a , so how is that done with two tx and rx cables ? i dont understand while the hex is still in the pic

if the nextion hex is within pic then you must transfer them through a serial(uart) port .

I understand that you have 16x2 lcd now.
You want to replace it with nextion touch type.
For that you must rewrite your original display routine for the touch type and in the nextion format.

a complete rewrite is necessary.
