Hey Fernando,
The protocol is documented here: http://firmata.org/wiki/Protocol
A digital message will give you a 'port', which is 8 pins. The
digital command is 0x90, and that's combined with the port#, so 0x90
means digital port 0, 0x91 means digitial port 1, etc. all the way to
0x9f which is port 15. Pins 24-37 are on port 3, so you want to look
for messages starting with 0x93.

Hello
I am triyng to expand Pduino to use with arduino mega. I founded
Pduino-0.5beta6-mega patch in this web site http://www.pjrc.com/tmp/firmata/readme.html ,the patch works prety well but its implemented until digital pin
23 and i need to implement the rest of the pins. If I add the rest
of digital pins in /pd sending digital outs/pd generate digital out
messages/ just like other pins are implemented, pins from 24 to 37
are not working. I has been trying to understand how the messages
system works but i cant really understand. By example which kinds of
values i must get if i print values from arduino/pd command
processing/pd digital-out outputs? where i can found and
explanation of how the messages sistem works, by example in the
subpatch /pd digital-out ?thanks _______________________________________________ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
