I thought i’d try to use python to control a blinkstick flex, but even the sample code is throwing errors for me and I can’t for the life of my work it out.

I’m attempting to run:

"from blinkstick import blinkstick

bstick = blinkstick.find\_first()

bstick.set\_color(channel=0, index=12, name=“red”)"

and it throw these errors in idle:

“Traceback (most recent call last):  
File “E:\Documents\Aidan’s\Python Scripts\LED\blinkstick v1.py”, line 5, in   
bstick.set\_color(channel=0, index=12, name=“red”)

data = (c\_ubyte \* len(data\_or\_wLength))(_[c\_ubyte(ord©) for c in data\_or\_wLength])  
TypeError: ord() expected string of length 1, but int found”

Any ideas? Am I missing something? I have installed blinkstick module as when I type “import blinkstick” I don’t get any errors.

Thanks

You cannot delete the thread, but it´s good for documentation for the next one searching for this kind of problem.
