IO Expansion in Nexys3 board

[Gowtham Raj]

Hello sir,

               I am using Nexys3 board along with digilent adept for bit file download. But in this board there are only 8 switches. I have seen there is possibility to extend I/O ports virtually with the help of digilent adept but how to use this feature. What is the procedure for this? If suppose i want to implement 8 bit adders i need (8+8) 16 input ports. How to achieve this with nexys3 board?

Hi Gowtham Raj,

I have asked some of our applications engineers about this, they will get back to you here on the forum.

Thanks,

Hi Gowtham Raj,

This can be down using the I/O expansion component found on the Adept2 page on Digilent.com (here's a link to the zip). You can follow the IO Expansion section of this guide to get you started. Let me know if you need any more help!

 

Good luck!
