[nothorius]

Hello to all,
sorry for if you know how I can configure on a 74HC595 based card so that it can exploit gpio inputs and outputs to control the relays? or possibly show me a card that can expand the I / O gpio in an optimal manner.

the card and this: http://www.52pi.com/en/raspberry-pi/63- ... dule-.html

Thanks for your help

Thanks for the reply,
I've already seen the link you sent me and I had seen it. unfortunately I do not understand how to load libraries that are mentioned necessary to wiringpi and create the program to configure the inputs and outputs.

Ok. Then I can't help. I see that there is 'How to download' and also quite many program examples.
I don't have any expansion cards so I am not able to donwload and test any of those.
