LED's like the light of the Knight Rider car

[zäpfle]

Hello,
I looking for a solution:
I tried to program 6 (or more, it sould be flexible) LED's and this LED's should goes on / off like the light of the Knight Rider car. I tried this with loops, shift register, sequence, arrays, jk flip flop and a lot of other things, but I couldn't find a good woorking solution.
Do anybody have the same problem an give me help?
thanks and greetings Peter

Hi Peter-
 
Here's a quick method I came up with.  It adjusts to the Representation width of the shift register initialization constant (i.e. the left-most '1' on this diagram).  So, it will work for u8, u16, and u32.
 
To use this with DAQ you probably just want to use the DigitalOutput>MultipleChannel>SingleSample>1D array of bool instance of the DAQmx Write VI.  You'll need to specify a line grouping of "One Channel For Each Line" on the DAQmx Create Channel VI.
 
I'm sure this could be done in a more optimized way- does anybody else want to give it a shot?:smileyvery-happy:
