Hello,
I am trying to create a VI that will register a transition change on a digital line, from both low to high and high to low. Right now I am using a modified version of the Digital Graph Pattern Search example to find the transitions, but I need to look for both "10" and "01" patterns in the data. It doesn't look like my VI is registering the correct index times for transitions, and I was hoping that someone could help me figure out why.
I have modified the example VI by adding another Search for Digital Pattern VI, ANDing together the match found results, and interleaving the arrays- I think this will work because the pattern should always be low, high, low, high, etc.
Right now the VI doesn't seem to register transitions on the first few or last bits of the digital array. There are also some times that the loop will hang, even though I think that I'm incrementing it correctly. Is there any reason that this should happen? I am using LabVIEW 7.1
Thanks for any advice!
