Hi all,

I have some trouble running firmata on the pro mini. Although the same patch runs fine on both my Duemilanove's.

Apparently firmata isn't entirely the same on these mini's. Although Since arduino 0017 I can connect and send data, it's not without errors. First of all

[arduino]_WARNING_currently_unsupported: 176
[arduino]_WARNING_currently_unsupported: 160
[arduino]_WARNING_currently_unsupported: 176
UNKNOWN_INPUT_COMMAND: 0 10263
UNKNOWN_INPUT_COMMAND: 8 12339
UNKNOWN_INPUT_COMMAND: 11 9710

Is what I see when I try to run the pd patch. lot's of those, thousands...

Another weird thing is that even though pin 13 is unconnected on the arduino, It's the only pin that seems to work. I really don't get it. Is there some sort of different mapping? normally only pin 9-10-11 are supposed to work.

yet another thing id that PD becomes very unresponsive (waiting for serial data??) is this normal behavior if the firmata is buggy or something?

any ideas anyone?

i guess the problem is the ftdi connection. are you using the cable or sparkfun breakout or what? does the upload with a blink example work?
i tried this, too.. without success as well. i gave up after a while, since firmata without a computer is useless anyway, i just use regular arduinos to avoid that confusion.
also, i remember that the sparkfun breakout didn't have exactly the same pin connections, does it?

I'm using this sparkfun breakout (the 5v version). Any alternatives for that? and I'm using the nano because I wanted to miniaturize, but I will use an duemilanove until firmata's fixed. thanks!

The StandardFirmata in 0017 turned out to be kind of buggy, unfortunately. We have things mostly fixed in SVN, but would love to have more testing and bug reports! So here's a new release.

I tested this on a Diecimila, I hear there are troubles with the Arduino Pro and others, but I only have the older ones, so testing and bug reports on those are very helpful.

great I'd love to do some bug reporting, can you point me to some standardized test or should I just try the pduino testing patches?
I will do the testing on both linux amd64 and OSX leopard

regards

I don't have any standardized or scripted tests, the idea is to just try all of the features and see if they work. I usually just run thru the pins with my pot, switch, LED, and servo.

Hans,

I just downloaded the http://at.or.at/hans/pd/Pduino-0.5beta3.zip package.
results of my tests:

on the duemilanove Atmel 168 SimpleAnalogFirmata:

quick testing seems ok, but only harwarePWM (no soft pwm on e.g. pin 13) I don't know if this was intended, but in the source it says:

/* Supports as many analog inputs and analog PWM outputs as possible.

So I was hoping for automagic softPWM, but for the rest everything seems fine (I tested PWM digital out)

on the nanopromini I saw some weirdness...
first of all I could not compile firmata for it on linux (32bit) in arduino0017 or at least not upload, so I think it has got to do with the cable I use. which also explains why I cannot send data toç/from linux I guess. On OSX this upload works, and [pd device info] reports firmata-237.220 and also SimpleAnalogFirmata-0.1 This seems ok, but I think it still wrong somewhere.

I I just upload a patch that fades some pins, everything seems ok. With firmata <-> pd the arduino gets hot and operation seems a bit of what to expect.
I'll have to run more tests later.
al I can say for sure is that the problems from the first post (unknown command) remain.

I need to get my scope back or at least a descent multimeter
I'll test some stuff later this week

" as possible" is the key word there. So far, no one has implemented automatic soft PWM... but its definitely doable.

We have a new release we a major feature and minor fix:

• Shigeru Kobayashi added support running servos on almost all the pins!
• Hernando Barragán added some fixes for building for the Wiring board.
