Issue trying to use NeoPixel Stick ProffieOS

Hi there, this is my first time posting in this forum. I’m hoping to get some help with an issue im facing. I have a proffieboard v3.9 and I’m trying to hook up a NeoPixel Stick. The actually stick im using can be found here. I made sure the stick worked with my code by testing it out on an arduino uno. The stick works fine and lights up green, however when trying to use the stick on the proffieboard, the entire stick lights up with green, blue, red and repeats on the entire stick. I have the 5v pin of the the proffieboard going to the stick and the gnd going to the proffieboard gnd. The data pin i’ve tried many different pads like free 3, data 3 and even the LED 4 and 5 pads. My hope is to use the stick as a battery level indicator. I added the following code to the ProffieOS.ino file. #include <Adafruit_NeoPixel.h> Adafruit_NeoPixel strip(8, NEOPIXEL_BATTERY_LEVEL_PIN, NEO_GRBW + NEO_KHZ800); setup() { strip.begin(); //reset of the setup code } loop() { if (SaberBase::IsOn()) { strip.clear(); for(int i=0; i<8; i++) { // For each pixel... // Here we're using a moderately bright green color: strip.setPixelColor(i, strip.Color(0, 150, 0)); strip.show(); // Send the updated pixel colors to the hardware. } } //rest of the loop code } This is how the stick lights up with that code on the proffieboard. [led_stick] I’m not sure what the issue is, is there a better way to achieve what i’m doing? Has anyone used this library with their proffieboard? Thanks.

They are using this driver I think:
