Using morph on blinkstick pro with smart pixels

[dillonusrey]

Hi folks, I’m a novice with both the blinkstick and python. This is my second noob question with more to come I’m sure.

Using a blinkstick pro in mode 2 with 2 smart pixels connected to R channel. Trying to set color and morph the two pixels but am getting errors when trying to control the second one (index=1). index 0 morphs the first pixel no problem. What am I doing wrong?

from blinkstick import blinkstick
bstick = blinkstick.find_first()

bstick.set_color(channel=0, index=0, red=0, green=255, blue=0)
bstick.set_color(channel=0, index=1, red=0, green=255, blue=0)
bstick.morph(channel=0, index=1, red=255, green=0, blue=0, duration=500, steps =100)
bstick.morph(channel=0, index=0, red=255, green=0, blue=0, duration=500, steps =100)

Hey Dillon,

please take a look at this post:

Error when trying to use pulse() multiple times

OK, it´s not your code. Pulse does not seem to work for a single LED at the moment. This must be a problem in the library or maybe with the device firmware itself. The pulse function needs to get back the current color of the LED and this seems to work only once. There is a similar problem with the python lib: https://forums.blinkstick.com/t/blinkstick-nano-bottom-led-morph-and-pulse-cause-error/787 So I fear I cannot help here and we need to wait for @arvydas

The lib does not seem to work for single LED pulse. Morph is the base for the pulse function so I think it is the same problem.

Ah. You are right, same issue with pulse. Ok well good to know it’s not just me. I wonder if there are any plans to resolve that? Or if anyone has written a workaround that does something similar to those?

Only know that it have to be fixed.
Workaround could be to program an own pulse function which do not need to get the current color directly from the device.
