XHC-WHB04-4 Python component

What if you had two buttons pressed, and released one. How could you know which one was released?

What are you trying to do?
You can simply save the state of the pin you are interested in and compare it with the value of the said pin in the next iteration.

For a more Pythonic way investigate this:

Well, like for example, the function keys. You need to know that the Fn key was not released.

I've updated this to work with LinuxCNC 2.9+ and Python3. I also added the secondary function buttons that the original code was missing. I rather prefer this component over the built-in whb04b component *because* its written in python and I can easily modify it to do whatever I want. Thank you to the original author!
