Hi,

Im not sure if this has been answered before but this has me stumped.

I am looking to hook up multiple 595 shift registers with separate data in ie:

registerOne will receive data from dataPinOne.
registerTwo will recieve data from dataPinTwo.  

now the first register works perfectly, register two does not receive anything. if I change the pin allocations for one to reflect two it works as well. I have separate clocks for each register but a common latch. Is this where i'm going wrong?
how should they be wired up otherwise?

Thanks for you help

Sorry I have figured it out, I didn't set the second data and clock in void setup() as OUTPUTS.  :smiley-eek-blue:

thanks anyway

Well for starters the thread title needs some work :)

Hey Greynomad, I think that is a new type of IC that Intel is working on  ]:)

Yeah, I think I read about them on EEweb a while back.

How's things down in the ACT? I come from there and still pass through every couple of years on my way to somewhere else.

I still like the place although I can't handle the cold any more. Maybe we'll cross paths next time I'm in town.

You know there's a maker shed in Downer that does a lot of Arduino stuff.

Got the notification yesterday that this thread was started through my phone and I had to do a double take because of the title.
Silly little shit registers.

Oh I have only just spotted the miss spelling in the title.  :smiley-roll:

They are really quite good registers actually.

As they used to say on Block Busters*

Give me an F please Bob.

That is all I'm getting that sorta makes sense. (I'm in the u.s.)

Greynomad - yes I'm not a big fan of the cold either. I saw that there was a hackers club here Make, Hack,Void (catchy name) and was wondering how strong the Arduino element was so I should check it out.Happy travels, Pedro.

Well it looks like the same show. In the UK it was a kids program:-

http://en.wikipedia.org/wiki/Blockbusters_%28UK_game_show%29

The big joke was always when a contestant asked for a "P" which is slang for urination. There was never a double entendre when they asked for an "F" which sounds even ruder but fitted the context.

That's them. I think the main player has an Arduino clone on the market.

Smart man... start a club, distribute a clone then hock it to the members.  8) That's free enterprise for you.
