8x8 matrix scrolling text, change text from webpage/app

I'm trying to make a 8x8 matrix scrolling text using user input from a webpage text field.

The board should update when the form sends from the webpage.

This is what I've got so far: I've got it working with static text. I've also managed to make it fetch text from a .txt file and output it to the matrix, but this one doesn't scroll the text.

I want a matrix that outputs whatever you or someone on the other side of the globe writes, and it needs to scroll. Anybody knows how to do this? I've understand that writing to a txt-file should be possible. But I don't know how to trigger it to reset the board with the new text only when the text is actually changed.

I need to say that I'm using a wemos D1 (first model, not the second) board with wifi onto it.

Here are the two programs I've been testing, but I think I will have to scratch both of them in favor of some new code to make my wishes come trough.

Thanks for any guidance or tip.

There is a sketch for the Parola library. https://github.com/MajicDesigns/MD_Parola/tree/master/examples/Parola_Scrolling_ESP8266

It is written for Arduino, 8x8 LED matrix, and ESP8266

I haven't personally tried it.

You may be able to get some ideas from it.
