C# reverse output?
 

hello,
if I've done

or
and I want to verify what I've done, so how can I check, what was outputted at the last time to port 888?


Thanks!

i'm am not familiar with port programming under c# but i'd be fairly sure that this is impossible. it's your own responsibility to track this kind of data, maybe using a history buffer to hold old outputs. indeed you might want to factor out the writing and buffering to a seperate function, so your main body of code just calls a function with a single value, or writes to a buffer and a dedicated function handles it all.

yes.
re thought about it, the solution is to get a variable changed whenever output has changed, so the variable will hold the last output.


Thanks anyways!
