trying to find a simple example for my basys 3

[rscott9399]

All I want to do is read in a pulse. 

I was to use an input pin of some voltage to read a pulse. Thats it

It will be the start of a quadrature encoder module 

I cant find anything out there. I am really surprised that there is no simple example. I dont want to use a VGA monitor or run a 7 see display or anything. All I want to do is turn an LED light on when it gets a pulse. Simple

 

Anyone know of any tutorials for such a type of thing.

Learn Verilog or VHDL. Your quest would be simple.

It's amazing what you can do with very few structures like shift registers, 1-bit adder/subtractors ( AKA up/down counters ) storage and simple state machines. All of these are (usually) trivial. the hard part is understanding time, concurrency, and how HDL gets implemented in a programmable device.

There's plenty of source code in the Project Vault to use as templates as you learn. There's only one way to learn...take the first step.

BTW, before programmable logic these same structures were used to create quite complex logic out of a handful of MSI/LSI devices. The world hasn't changed in the past 50 years as much as many people assume.
