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...

Do you have any other FTDI connect devices to try? But this setup works with other chips right? Also you mailed us your name and address right?

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...

Re: Same old, same old Connect problem.

Hmm,

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.

Re: Same old, same old Connect problem.

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.

Gokul,

The amp should be on by default. You have an audio signal going into the board?

Hankus,

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.

HillyOTM, The type of LEDs don't matter. Confirm voltages at the chip with a multimeter. http://arduino.cc/en/Hacking/PinMapping Confirm that the chip is in the socket in correct direction (look at the silkscreen on the board for the divet).

Re: Yet more RBBB upload problems

Hilly, The light on the RBBB is a pilot light - just means power is good. Try hooking up an LED to pin 13 and hitting the reset button. If you see a flash then, it means that there is a bootloader on the chip. If you bought the board recently, it has Uno (Optiboot) bootloader. If it was manufactured...

Re: Compilation errors LibHumidity and LibTempTMP421

I'll see if we can get this up and running on a Mega and find the issue. Maybe some referenced library broke.

Switch the board (in the tools menu) and see if it compiles - I don't think it will from the messages.

Re: Sharp (AMBI) vs the Vishay Temt6000 Sparkfun

Elina, Sorry I can't understand what is going on in your thread. No voltage output on the sensor? Did you put a multimeter on the output? If you put a meter on the output and can't see it change, the odds are that the sensor is damaged. That particular sensor doesn't suffer reverse polarity very wel...

Carloscoleman, Are you having issues uploading? Try try the UNO board setting - if no luck maybe you have an older board. Try the Duemilanove setting. Still no luck? Put an LED from pin 13 to ground through a 220 - 1k resistor. Push the reset button and see if the LED flashes - that's the bootloader...

Re: USB BUB I upload problem

It's slightly weird that it works with older bootloader but not the new one. The upload speed and timing are different on Optiboot which probably makes the floating logic line issue problematic. I'd say confirm that the logic line pin is not floating on the BUBII and that the headers are soldered on...
