Looking at his pictures he is saying he wants the red bar when there are no yellow bar appearing/overlapping
Which post#26 state machine would do
Your Reply #26 does not mention measuring the width of the red pulse.Also, I have the impression that the OP wants the output to be HIGH simultaneously with the short red pulse being HIGH and that the output should never be HIGH if the red pulse is long....R
Yes Exactly. I understand that with the Puls Width method, i can only get an output after the short pulse has occured.
unless there is a repeating sequence in which the short pulse always occurs after some other series of pulses.
This is not the case, there is no repetition.
You are only replying to small pieces of the comments. You need to describe the whole system. In Reply #34 you seem to be implying that identifying (or responding to) the short pulse after it has happened is not satisfactory Then in Reply #37 you seen to acknowledge that you can't detect the short pulse until afterwards but you have not linked the two issues so it is very hard to know what you really need.I suspect it can be done, but until you tell us what is needed I can't suggest how....R
The camera just outputs these two digital signals. This is the data i receive, and whatever needs to be done has to be done after the camera stage. I just want an arduino to receive these two digital signals and give me an output when the short pulses occur.
Why?This all seems strangely secretive. What do you propose to use the Arduino output pulses for? ...R
The Arduino output triggers image acquistion in LabVIEW.
How I understand the original post.
