This below from the ws2801 datasheet , I think this means they can be up to 6 meters apart. ?
The Connection and Driving of Cascading Operation The transmit the data over long distance by cascading, the WS2801 integrates push-pull output stage with strong driving capability which enables the data and clock can be transmitted up to 6 meters at 2MHz clock frequency. To prevent the reflection, it is necessary to connect a 50Ω resistor at the data input or output port for impedance match. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
