This code is meant to do many things at once:
Primarily:
- it shifts digital signals through a digital output while also reading in digital signals and saving the inputs to an array. (That's most of the top code)
- it will also output specific trigger signal (low before the user hit's 'start', high while the code runs, and low again after the code finishes up).
Currently, I've set up the program so it runs based off a timer in the while loop. I'd like to eventually have that run according to the rising edge of an external clock that I'd provide with a function generator and input through a digital input pin. This is where I'm shaky - If I understand correctly, the trigger block allows it's task to execute according to the rising edge of some source clock. I made the source a control such that I can point it to the specific pin where I'd connect my function generator.
I threw the sample clock in there because every sample I looked at had one - but I'm unsure what it's doing.
Is the 'sample clock' block exclusively used when you're using an internal clock signal?
Thanks again,
