We are currently sending over an array that contains four 255s, 32 sets of 255 , 50, 50, 50 and then four more 0s. Does anyone have a LabVIEW library that already works with the DotStars? Any help would be greatly appreciated.
First, I'm going to assume that you meant MOSI, saying I have no idea what MOSL is. The Adafruit guide mentions that the DotStars may not work with 3.3v signals, which the RoboRio provides. You can use a signal level shifter such as this one to change this: https://www.adafruit.com/product/1787

NOTE: I've never used the DotStars before, so this may not be a problem.
