LED sink driver and Arduino question.? Answered
Hi ... I would like to ask, if I can use 2 of these LED sink drivers uk.farnell.com/jsp/search/productdetail.jsp by using/controlling them just from 3 pins on my Arduino ???
I think, that it should be possible thanks to the pin22 SDO (datasheet www.farnell.com/datasheets/456099.pdf) ... what do you think ???
If yes, is there any limitation on HOW MANY shift registers/LED drivers you can connect "in a row" by using just 3 pins on Arduino ??? Could I use 4 of these drivers and control them just by 3 pins on Arduino ???
Thank you in advance for your answers...zholy
