Tom,
As you say, we have a number of working sketches now. I think there are still a few tweaks to do though. I like whatt you did with the PN532 sketch where it flashes the led for the number of readers and lists which ones are connected to which pins. That would be quite nice to have on the MFRC sketches too. Currently, the PN532 sketch is Serial only. I think it would be good to have an ethernet version too.
So far, I've really only tested one reader with an Uno for these sketches. We need to test them on Nano's and Mega's to be sure. I also need to test multiple readers once the hardware has arrived. Then we can see what issues, if any, we get with 8 readers into a Mega. We might have to use a multiplexer and this would need to be added into some of the sketches.?
Once we've done that, I guess it's time to look at an easy pcb board for connections. I quite liked the idea of a Nano plugging into some headers on the pcb. I see you can get an Ethernet Shield for a Nano too? think it would also be useful to make provision for connections to Uno's and Mega's.
What are your thoughts?
Steve
