Once I fixed the baudrate (thx!!!) it works fine. One student has
trouble with an ATMEGA328 that I will have to troubleshoot tomorrow.
Good idea to make a specific release, or at least label it in some way
that makes it clear. I know it's ugly to support very old hardware, but
I think there are a lot of those things out there in the world still.
Best,
D.

Keep in mind this is beta software so you were just a beta tester. It
would be great to incorporate your experience into the next release.
Perhaps the best way to support the ATMEGA8 is to post a firmware for it
somewhere, like StandardFirmataATMEGA8. It would just be
OldStandardFirmata/StandardFirmataV2_0 renamed to StandardFirmataATMEGA8
and with the baud rate of 57600.
What is only a question of the ATMEGA8? Or where there other problems?

Hi HC,
thanks for clarification. I will try to find some time to stick it in
the FLOSS Manual Pduino chapters later on. I did get the ATMEGA8s
running with the new baudrate, now I have a problem with the ATMEG328
but I will deal with that tomorrow.
I tried to get all 12 students using same versions of everything but
you know how hard that can be. What was supposed to be a 10 minute
installation took the entire afternoon, along with questions about
motors, circuits, mechanics and everything else in the middle of
debugging. Not an optimal moment for concentration to fix a glitch...
maybe I will stick to hardware-only workshops from now on, computers
are only good for causing ulcers and hairloss!
I landed here Sunday and started the workshop the next morning so I
had no time to investigate what hardware the school had. I told them
they should upgrade the ATMEGAs they have but you know how long that
takes at any kind of institution ;-)
Best from Helsinki!

List goofballs aside, I think it would be good to clarify all this
stuff.
The split between the things available on HCs site and what comes
with Arduino is quite confusing. I was only using the ones from HC
to keep the versions matching.
No argument here, its just a matter of finding the time to do it. With
Firmata 2.1 the baudrate should be totally stable (that's the big
change between 2.0 and 2.1), and further updates shouldn't cause
issues. I'm working on finalizing the Pduino 0.5 release.
The Arduino-provided Firmata stuff does not contain the Pd objects
themselves, and if the Pd objects must match certain Firmata then it
would be good to make a note of that somewhere... maybe on the site
where the Pd stuff is downloaded?
For the latest Pduino, either use the included one, or the one in
Arduino 0018.
And besides that, if some Firmata says it supports ATMEGA8 then I
believe what it says. I spent half of yesterday smashing my face
against the keyboards of 12 students, trying to teach them something
that was broken, and the reason it was broken was not documented. So
yes I get a bit cranky!
Firmata is an Arduino library which fully supports the ATMEGA8.
StandardFirmata is a firmware that uses the Firmata library that is too
big for the ATMEGA8. As a teacher, I would highly recommend avoiding
the ATMEGA8, they are not well supported by the Arduino community.

Peace out dudes,

Where do I find the matching Pd Firmata objects for the Firmata in
Arduino
18 then?
Maybe all of this could be a bit better documented? ;-)
