Hi,

I'm taking an electronics class for college and I am very behind because 
of some family issues that I've been dealing with. I need to pass this 
class to graduate.

I am trying to connect this LCD character display: 
https://www.mouser.com/ProductDetail/Newhaven-Display/NHD-0208AZ-RN-YBW?qs=sGAEpiMZZMt7dcPGmvnkBq9RSAvEJGmRHW9dooi1h5g%3D

to the Arty-S7-25 FPGA, and program it using my computer to display 
text. I have no idea how to go about this, and the steps or software 
that I have to use. I have read that Vivado, and Verilog might be 
useful. If anyone could provide a general guide, or tips to doing this 
as quickly as possible I would really appreciate it. Would this be 
easier to do using an LCD Driver? And if so, how would I go about using 
it?

Thats a usual HD44780 compatible display.

You will need to spend some time on this execise. It is tough stuff and 
there is no shortcut to do it in half a day...

Vivado is the toolchain for Xilinx devices.
And Verilog is a hardware description language. VHDL is one also.

Install the toolchain and start with 1. simulating a flashing LED and 
then 2. run that flashing LED description on your hardware. Then do the 
very same same with a chasing light. And then have a closer look at your 
exercise.
At that point you can use Google:
https://www.google.com/search?q=verilog+44780
And as always:
1. simulate it
2. run it on hardware
