Hi to all, this is my first question here I need to build a simple device that sends over ethernet an udp packet when a key on ps2 keyboard is pressed. Specifically i'm going to attach only the numpad and nothing else (i need only 4 keys). Looking around i've seen that netduino have some issues (related to the firmware) that cause some troubles when using a ps2 connected to netduino (using arduino schematic) http://forums.netdui...rd-timing-woes/ Before i buy this stuff, can someone confirm that i can attach a ps2 keyboard to netduino? (and link some docs ) I'd really like a lot the idea to use C#/Micro Framework to develop on arduino Thank you!!!

Hi Daniele, Welcome to the Netduino community! I haven't had a PS/2 device connected to my netduino yet, although it should be possible to program a driver for it. Since you only need 4 keys, could this be a cheap and easy solution? http://forums.netdui...ver-and-scheme/

Thank for your answer! Yes, it's perfect ... now i must found an european distributor (italy preferred) ... it will be hard In any case, there are problems with PS2? PS: sorry, i've seen only now that there is a section on the forum for the netduino plus :\

Check http://www.sparkfun.com/distributors and search for Italy. There are several distributors.

No problem at all, it's quite a general question, not Plus specific so far. I moved it to Netduino Plus for you

Thank you.

I've checked all italian distributors, no way ... i'm going to check all german distributors.

Anyway, for another long-term project i need to use a barcode ... so, in the end, i'll probably use a netduino plus with a ps2 attached (if it's correctly supported)

Hi Daniele and Stefan.
It seems that the PS/2 interface looks very close to the SPI one. So far, I guess should be pretty easy to connect either a keyboard or even a mouse to the Netduino (any model).
Please check at these docs.
Cheers

Ohh that looks interesting actually! Not exactly like SPI because one pin is used for both Rx and Tx and there is no CS pin, but it looks like the host defines the clock and that makes it possible for Netduino to work with.

-edit- I see a success-post here: http://forums.netdui...rd-timing-woes/
Requires modification to the firmware though. Perhaps it would be nice if PS/2 support would be built-in the firmware. Chris, reading this?

[Daniele Salvatore Albano]

this would be awesome by the way, there are contraindications in using that firmware patch?

I always advise to use stable soft/firmware, especially when you're new to Netduino. On the other hand, it's always possible to reload stable firmware when you encounter any problems. So no harm in trying it out.

ok, thank you
