1  Using Arduino / Networking, Protocols, and Devices / Re: OSC libraries compatible with EtherCard on: June 10, 2013, 12:42:33 am
We just released this one
https://github.com/CNMAT/OSC

I have only tested the UDP stuff with Wiznet ethernet but we use the regular Ethernet library
so it should work.

you might find the examples in our OSC for Arduino library helpful.

We fixed that bug a while ago, please take a fresh look at

There is a lot of speculation here about OSC.
It is a binary encoding that can be  is usully sent as UDP or SLIP encoded serial.
You can find a full Arduino OSC library here with plenty of examples:

First of all, thanks for your help !

Quote
The Arduino WiFi Shield library is the only library which work with the WiFi Shield. So the only solution is to try with this library, but I didn't found the transfer mechanism on it...
The WiFi library establishes the connection between the Arduino and the PC.

The UDP library manages the transfer of packets. It doesn't give a rats ass what's in the packet.

You've got a packet that contains some data that you don't know how to process. Why not look for a library that does know? The one that Sembazuru mentions bears looking at.

I agree with you, but the data is not received on the WiFi Shield and on the Ethernet Shield with the same protocol, and with the last Arduino library (which is the only one including Udp exploitation), all files are like "merged", they works together. That's why I'm not able to import an Ethernet library (modified) to work with the WiFi Shield, and on the link that Sembazuru sent (thanks to you) we can see here http://cnmat.berkeley.edu/library/oscuino/controlling_oscuino/touchosc that all files are build to work with Ethernet...

I'm starting to go round in circles because of I'm not familiar with exploitation and the modification of open transmission libraries. And don't find much support and examples for this Shield smiley-sad

It is true that the UDP examples we included in the first OSC for Arduino library release use the Standard ethernet library but we carefully factored the OSC handling itself to be independent of the transport protocol. It should be easy to adapt to any I/O that uses the Stream class.

Thanks for your interest in OSC.
My group has just released the most feature-rich library of OSC for the Arduino and variants.
It addresses UDP and serial encodings.

You will find Processing and Max/MSP and PD examples as part of the library demos.

Interesting. Carefully written C++ can be as fast as C and often faster because types can be managed more flexibly.

Have you compared the footprint of your library? It is probably a little smaller as it doesn't support multiple serial ports. Is it faster?
9  Forum 2005-2010 (read only) / Development / Re: Arduino Sine wave Generator on: December 13, 2009, 02:07:27 pm
The quality of this kind of sine wave is limited by the 8-bit table and the analog reconstruction filter you need on the output of the pwm.

I would be careful about building measuring tools with this approach,

My  implementation of the DDS  algorithm for Arduino has a parameterization of the algorithm that could be adapted for different resolutions and table sizes and comes with some examples of how to smoothly interpolate frequecy and amplitude for <a href="http://www.adrianfreed.com/content/arduino-sketch-high-frequency-precision-sine-wave-tone-sound-synthesis">Arduino music and sound applications</a>
10  Forum 2005-2010 (read only) / Development / Re: Numerically Controlled Oscillator (NCO) on: December 18, 2009, 12:52:47 pm
I prefer to have a bigger table and keep all the conditional code out of the inner loop. My NCO code can be found here for reference:
http://adrianfreed.com/content/arduino-sketch-high-frequency-precision-sine-wave-tone-sound-synthesis

It has the interpolation code you need to smoothly ramp frequency and amplitude if you want to make clean music synthesizer out of this idea. I also include the tables to map midi note numbers into phase increment values.

You could just make a 3.3V shield with appropriate power supply from USB 5V (a la seeeduino) and some shields just wont work (or work as well).

I don't use shields because my applications need something much
smaller. I suspect most users of this device want the small speed so things like a small connector for lipo (and the charger electronics)
would be attractive.
I just need a 0.1inch breakout board with the FTDI or sparkfun dongle pinout. I suppose for this the nano pinout could be emulated, but I am not attached to that as I use teensy for most projects.

The boardID concept is definitely needed unless the Arduino leaders
believe there should only be one best standard "Arduino" board for each chip.

"We decided to go for Diecimila because the RFA1 is a mega1281 device and has less ports then the mega1280 used on the mega arduino.  

Here is the current pin wiring, any advice is very welcome, because
we are not sure what to do, whether to sprinkle around with the megaRFA1 ports to match exactly diecimila mapping or keep RFA1 ports intact and bundled. Generally the second level AVR functions generate headaches:
- does some shields use T0/T1 ?
- swap AIN0 and AIN1 to have a PWM at D6 ?
- is ICP at D8  used from anybody?
- MOSI and /SS have now PWM at megaRFA1!
"

Good idea. I would use the seeeduino as a reference.
In particular it is a shame to lose the two extra analog inputs to
the digital ports as you propse.  On the seeeduino they are placed on two addtional pins on the bottom row.

I am using the same development board as you. How can I help without duplicating effort?
I was going to start from the 1281 arduino software port you can find
here: http://sites.google.com/site/arduino1281/

Also, there are so few variations from the atmega1280 code how
can we get the atmega1281 and Atmega128rfa1 conditional
code into the core?

They announced RF4CE certification so presumably prototypes exist.
It takes a while to design and build a board so why not start now? The pinout and recommended circuit are established.

The claim is that
"The Atmel Atmega128RFA1 is available now with a suggested price of $4.78 for 10K quantities."

Anyone planning to build an Arduino IDE compatible board with the new AVR with integrated zigbee?

http://www.atmelroma.it/dyn/products/product_card_mcu.asp?part_id=4692

I am collecting up your feature requests for a board.
My own enthusiasm is for a small footprint like the teensy or nano.
What about these ideas:

Lithium charger and battery socket?
lilypad form factor?
