WS28xx/APA102/UCSx903/TLC59711/P9813 configuration

All parameters are optional. They all have a defined default value.

The WS28xx configuration can created with file "devices.txt".

Singleport (1x)

Multiport (4x / 8x)

Power saving

For battery powered operation a GPIO pin of the Orange Pi Zero can be connected to a MOSFET. When there is is no DMX or when the node is in time-out state, the GPIO pin level is low.
