Hello! I’m still here 🙂

I’m happy you enjoyed the experience! I often wonder how many kits are still in drawers, yet to be built! It looks like you’ve done a very neat job of it, bravo!

There was always a tradeoff to get all things functional at the same time. But to answer your question, yes, you can use 1 pin for both OE pins. And to answer your other question: Yes, you can also chain the RGB Matrix with the Digitiser (using Qh’ on one to connect to SER on the next) to save on more IO. It would be a little more complicated to code, but it’s definitely possible.

Let me know if you need more details. I am very rusty as I haven’t coded for my kits in a few years, but I’m sure I can help nonetheless.

Kind regards,

Martyn
