After assembling the kit I had it working fine for a couple a days while working on a clockface and wall mount bracket.
After assembling the led ring on the face and reconnecting the controller with much less cable between de ledring and the controller (aprox 30cm) the data towards the ledring became corrupted, leds are flickering trailing etc…
At first I tought that the wifi module radiation would probably be the cause of this, it was mounted right behind the ledring.
Placing the module a bit further away from the ring dit not solve the problem, the problem seem to be resolved after lengtening the cable from 30cm to 150cm…
But i can’t find a probable reason for this unless there is some compensation in the software for the added capacity in the longer wiring…
is there a minimal length for the cable between the module and the ledring ???
Another probable cause could be that the output on the module does not have an push-pull configuration (opendrain possibly ???)…
