LIFA + Shift Registers 74HC595

Hi, I'm tryin to use a Shift Register 74HC595 with labview LIFA but I don´t get the wanted result, and If you have an idea  please say it.

This is the code and an image of the controls, I want to turn on/off 8 leds on a protoboard when I turn on/off in labview...

Abraham94,

You can use SPI to talk to the 595 rather than having to control all the DIO pins yourself.  It will be much much faster that way too.
