Stepper Motor VI Output to LEDs

[Ev117]

Hello,

Looking for some help finishing a stepper motor VI and very much a novice.

I found the following stepper motor VI, where the VI indexes through a series of HEX numbers equivalent to the binary motor step sequence.

The sequence is outputed to four LEDs in the VI but now I wish to output to four LEDs through my I/O 6501 device. 

A DAQ assist has been set for the 4 I/O lines but when I run I get an error saying the task has 4 lines but the data is 8 so a bit confused.

Would be grateful for any help on this thanks.

your sending a 8 bit data...change it to 4

or

change the lines to 8

Your number to boolean array gives you an 8 element array.  You need to use array subset to make that a four element array.

Thank you both very much for your help, VI is working perfectly, added

an array subset with length 4 just prior to the DAQ assist, thanks again.
