sudo service hyperion stop
gpio -1 mode 19 out
gpio -1 write 19 1
DI (data in) -0.02
BI (backup in, I'm using ws2813) -5.16
gpio -1 write 19 0
DI (data in) -0.02
BI (backup in, I'm using ws2813) 0.00
Reboot (so hyperion active again)
Before making a change (color or effect):
DI (data in) -0.07 (white leds)
BI (backup in, I'm using ws2813) 0.00
Making a change, for 0.5s:
DI (data in) -0.01 (effect or color)
BI (backup in, I'm using ws2813) 0.00
After 0.5s:
DI (data in) -0.07 (white leds again)
BI (backup in, I'm using ws2813) 0.00
I didn't mix up the results from DI and BI!
BI and DI are correctly tied together.
It did work correct with the pi2.
When the leds have turned white after 0.5s and I wait long enough I can see the color I set before, again for 0.5 and than all white again, while DI drops to -0.01 and when the leds turn white again up to -0.07 again.
I don't know what you make of it, but I think I have a faulty pi0. And it seems that all tests are useless. Perhaps the same as this:
I searched the web and found someone with a broken pi zero wifi (in fact 2 were broken, the third he got was okay):

Loopback test okay: https://github.com/PiSupply/Pa…81#issuecomment-286412767
Third pi0 working: https://github.com/PiSupply/Pa…81#issuecomment-286723151
After 10 mins, not only the leds I addressed with hyperion are white (for testing purposing I reduced the number to 5):
led 6 pink
7 white
8 green
9 -13 black
14, 15 white
16 yellow
17-19 black
20, 21 white
22 yellow
23-25 black
26,27 white
28 yellow (although less pronounced yellow, more whitish).
There seems to be a pattern here. And maybe it's green, yellow green, white yellow?
Changing the color or effect on the first 5 leds, makes no change to the other leds.
