hmmm, if the patch cables to the ATtiny where to long, (including the one to the resonator) could that have an effect?

at the moment i have ribbon cable soldered directly to an SMD 85, the ribbon cable is maybe 8cm long. at the other end they are attac...

i am not sure how i would try software serial on a 328? the board has the FTDI chip hard wired to TX and RX, at the moment i am using the board with the chip removed just as a serial converter to drive the ATtiny. if i use the original 328, won'...

Pas mal ! HDMI, 4go de flash, support linux, SATA ... Bien mieux que la Rasberry à mon goût smiley Mais le proc c'est un A8 donc moins bien que la ODROID nan ?

Hi Lefty,

Thanks for the fast reply.
I've bought it at www.iprototype.be
They are an offical reseller listed on : http://arduino.cc/en/Main/Buy
I'm pretty sure it's an offical UNO REV3.

But i've also read about using FLIP to fix the bootloader, do I n...

Building a Dedicated Bootloader Board for New ATmega328P Microcontrollers

Frantone Electronics tackles Ladyada's dedicated boot loader board project.

From Fran:

The very first thing that I tried to do when I began my Digital Firefly Jar project was to burn bootloaders to newly manufactured ATmega328P microcontrollers.  I knew that to reproduce my project I would need to make multiple programmed ATmega328′s and in anticipation of doing many Arduino projects I bought the chips in bulk.  I knew that I would have to burn bootloaders to all of them in order to upload and use my sketches.  I bought a used Arduino Duemilanove to do this, and there was a clearly laid out tutorial about burning bootloaders on a breadboard on the Arduino site.   It seemed like a no brainer – an easy task – but it wasn't…  It just did not work!  Many attempts using the set up in the Arduino tutorial met with no success, so I went to the blogs and saw that many people were having problems doing this, and there were as many apparent solutions as there were issues.  I tried every configuration from every blog I could find on the topic: adding pull up resistors, changing power supply, altering settings, changing cables, etc….  but nothing worked.   The afternoon I spent trying every one of these configurations to burn a bootloader met with nothing but errors.

So I decided to go a different route and tried the dedicated bootloader board project suggested by Ladyada that used a very nifty Arduino sketch that had the Duemilanove's ATmega328 do the task, and this elegant set up works flawlessly.  Success!  And a really cool project too!

Vero! Serve per forza il tristate, altrimenti i led si accendono anche quando non vengono polarizzati, visto che i pin delle linee e delle righe, con il PCF8574 potrebbero assumere solo 0V o 5V.

If they are working with FTDI, doesn't that mean that they are working correclty?

I have seet PAN ID of both to 2001.

And ATDL is the bottom bits of the destination. Since A wants to send to B, ATDL of ...

I wasn't aware of this before, but Google has a decent style guide for C++ development.  There are some interesting points in here that are very relevant to C development as well, and I always find this kind of stuff really interesting to read.

Hi,

Yesterday my brand new (and first) Arduino Uno R3 arrived.
But when 1 plug it in the USB, i don't get the expected blinking led.
Instead the power led and the led close to pin 13 both stay on all the time. The power led is green, the other one is y...

Su Arduino il tipo int (o unsigned int) sono 2 byte. E' il long (e unsigned long) che sono lunghi 4 byte.

Faccio ammenda ,non li uso quasi più questi tipi di dato ......
