Topic: LPD8806 want to have pins 2-7 all send same data concurrently (Read 631 times) previous topic - next topic


I am trying to modify the code for the adafruit LED Belt Kit so that an arduino Uno will send the same info for datapin through pins 2-7 and clockpin through pins 8-13 concurrently.  I am trying to attach 7 belt strips (with external power) to run the same sketch concurrently.  Is there any way to do this with the software or will it require a hardware answer (software answer preferred)? 


Have you tried connecting more than one belt to the same Clock and Data pins?  In most cases you can output to multiple devices on a single pin.

Yes, it works for 3 strips in each pin but I am trying to wire up 9 strips so I need 3-4 datapins doing the same thing concurrently and 3-4 clockpins as well.
