Re: Compilation errors LibHumidity and LibTempTMP421

michael, I just checked both files and re-uploaded to github. I did find an empty folder where I thought the files should be so something went wrong in a transfer that I never found out about. Try them out and let me know your results. I was using 1.0.4 so it's also possible the Arduino guys broke s...

Re: Compilation errors LibHumidity and LibTempTMP421

Try the versions on GitHub and see if they work. https://github.com/moderndevice?tab=repositories

I'll check when I get to office on Monday - but I'd appreciate an email or a post here to let me know if the GitHub libraries get the job done.

Thanks,

Re: BUB II && ATMega644P - Some Help Please?

The Hermit, You installed all the Sanguino libraries in Arduino, correct? From what I remember the last time I used Sanguino chip I had no problems with the upload. I do think that what we are providing on the chip is the Duemilanove bootloader though and not optiboot. Let me check on that tomorrow ...

Re: fluxamasynth with duinomite

I don't know the form factor of the duinomite, but you can figure that out. The fluxamasynth mates with a standard UNO or Duemilanove form factor - but this is not at all required. The fluxamasynth could not be more simple to interface - besides power and ground it just requires a pin (for software ...

Re: What length antenna for 915 mhz?

tburt11, Sorry about the really slow reply - I just saw this slipped through the cracks. Why is the JeeLink shipped with an antenna that is not tuned for the frequency of the radio? It should be in the range of 80 mm. We have found it doesn't matter that much as long as it's close. Apparently someon...

Re: SHT21 Humidity and Temp Sensor - 3.3v compatible?

The SHT21 is completely 3.3V compatible. It has a 3.3V regulator on board and signal translation for higher voltage signals, but works great at 3.3 volts.

Re: Fluxamasynth and Arduino Mega

Charles, Q 1 Can I situate the synth in the same position as the ethernet board on the mega? I'm not quite following that - the synth board only really picks up 5V power (it has 3.3V regulator on board) and serial in from the arduino board - so if the power pins mate with traditional power pins, you...

You should see an "upload attachements" tab when you have the editor window open. Do you see that below the editor window?

Re: problem powering arduino RBBB from batteries

nmakro, The power system of the RBBB is really simple so everything is connected together. You should be very careful though with those batteries. If you hook them up in reversed polarity to the RBBB very bad things are going to happen. Also you definitely don't want them connected at the same time ...

Re: problem powering arduino RBBB from batteries

nmakro, I'm puzzled. You are measuring 4.8 volts at power pins from ground? One word of warning on those batteries - those are rather large batteries and they really should have a fuse or PTC or something in the circuit - if you hook them up backwards at the RBBB you are going to vaporize the backwa...

Sorry I thought my shipping person would catch that - stand by - trained engineers are working on your problem. Meanwhile I just remembered that the "Friend" uses RTS line for reset. Monitor the reset line with a multimeter and see if you see it toggle it all on upload? Try this and report back: If ...

Re: Extra output power pin on RBBB board?

Tony, Sorry for the Really slow reply I'm missing the suggestion. They will short-cut if the RBBB is pushed into a breadboard. People have been using these on breadboards for years - all the pins are in a row - how can pins short out? OK - it think you're referring to the input power holes. They wer...

Can you send some email to sales at moderndevice dt com for confirmation of your order date. I'm wondering about swapping out some chips for yours.

librav, Does your COM port appear / dissapear when you plug / unplug the friend? That will confirm driver issues. Latest drivers are here: http://www.ftdichip.com/Drivers/VCP.htm Are you using UNO setting on Arduino? It could also be Duemialanove if it's an older board from somewhere - we switched J...

Re: Audio Amp - is it off by default ?

The quiescent current draw? Under 10 milliamps I believe - you'll have to put a meter on it. The active current draw depends on the volume level of course.

The 2.1mm power jacks with 1mm pins are also available at Digikey, if you want to buy them there. CP-102A-ND
They're in our shop though, as you say. Email us for larger qts.
