Hi
I have fitted three spokepovs to my front wheel all spaced evenly and all the same distance from the rim.
I loaded the same image to all four banks of all three spokepovs with the same offset
But when it spins one of the three is out of sync with the other two the image is off by about 10 degrees
when i turn that spokepov off the image made by the remaining two is all in the same place.
where should i look to find the fault ?
one of my three is out of sync

I tried taking the microcontroller out and swapping it for one of the others
the problem moved with it, which suggests a problem with the controller ?

Re: one of my three is out of sync
All the pins appear fine and located fully in the socket.
But the image is still sequencing out of sync with the other two.
It works in isolation but in a different place on the wheel to the others, which is odd.

Re: one of my three is out of sync
if you turn the other two off (to make life less confusing)
does the image stabilize or is it flakey?

Re: one of my three is out of sync
If i turn the other two off the "faulty" one is stable but is about a quarter turn off,
as if the rotation offset is < or > the 220 that all three are set at.

Re: one of my three is out of sync
and you're super-sure that the rotation offset is correct?

Re: one of my three is out of sync
DOH !
I feel like such a fool.
I changed the first one to 220 but the others were still at the default of 255.
All working fine now, Thanks for your help. Loving your work.
