This is the example code im trying to use:
from blinkstick import blinkstick
from time import sleep, time
from colorsys import hsv_to_rgb
speed = 1
fps = 50.0
cut = 2
brightness = 1.0
stk = blinkstick.find_first()
cnt = 2
while True:
data = []
for i in range(1,cnt+1):
(r, g, b) = hsv_to_rgb(i/float(cnt*(1.0/cut))+time()*speed, 1, brightness)
data = data + [int(g*255), int(r*255), int(b*255)]
#print(int(r*255), int(g*255), int(b*255), i/32.0,)
stk.set_led_data(0, data)
sleep(1/fps)
This is the error im getting:

Im using a BlinkstickFlex Chip with 2 Leds attached to it. I used this code with the same board before once and it worked perfectly. I dont know why it doesnt now…
Im also using Pyhton 3.5
I searched around the Forums but couldn’t find any help to my problem.
