Finally reconsider your license... there has been these debates on the fora about derivative works and how they should always be distributed with the same license as the original. Last I knew Arduino was under the cc2.5 license.

Best,
B

It will be our first time releasing designs under cc lincenses. We read about the guideline, but not sure if we are doing in the right way. Thanks for the reminder!

Seeeduino, will be compatible with Arduino's CC2.5 share alike license. We see a explanation in http://creativecommons.org/licenses/by-sa/2.5/: A new version of this license is available. You should use it for new works, and you may want to relicense existing works under it. No works are automatically put under the new license, however. So we adopt cc3.0 share-alike licenses.

Please help correct us if wrong. Appreciated smiley

So we would switch back to FTDI, thanks for the suggestions.

Here is feedback from Silabs about the compatible issue, for your reference:
Quote
When a CP210x device (and any other USB device as well - no matter who the manufacturer is) is connected to the PC, it is uniquely identified by a combination of three identifiers - Vendor ID (VID), Product ID (PID), and Serial Number. If two or more devices with identical information are connected to the PC simultaneously, the operating system is unable to distinguish between them and only the first device or none of them will work correctly.
 
But if your application needs two or more CP210x devices connected to the PC simultaneously, there is a very simple solution, the CP210x devices should be programmed with unique serial numbers. The serial numbers can be modified in the CP210x EEPROM using the CP210xSetIDs.exe utility available as part of our application note AN144. AN144 can be found on our web site here:
https://www.silabs.com/products/mcu/Pages/ApplicationNotes.aspx
 
It is also strongly recommended that you use a unique  VID / PID  combination for your product to prevent conflicts with another manufacturer's products, more details about this can be found in our Knowledge Base article # 87271:

Ah.....nice.

Good idea with the second header on .1 inch centers, but not throwing away compatibility with old shields. Using this board, people can throw together custom shields with cheap proto donut board.

For USB, maybe place two jumpers that switch the USB D+ and D- lines to an ATTiny45. It would take up almost zero space. Now you can load the USBTiny or AVRUSB code and implement an HID separately from the main Arduino processor. Provide a couple female headers to run communication pins to the Arduino. I have firmware that allows an ATTiny45 to act as an I2C gateway for another controller, to appear as a mouse, joystick, or keyboard on a computer. Or, if you don't want to include the ATTiny45, at least provide the footprint and USB jumpers so users can populate that part of the PCB if they want to.

Yes, it's a easy. We would add this feature by 1) Pin out USB D+ and D-, 2) setup a jumper to bypass the onboard USB chip.

We want to use CP2102 instead of FT232
The CP2102 device has poor support under Mac OS X (that driver is the only software ever to crash the mac os x kernel on me).  IIRC it lacks a unique identifier, which is very important if you use more than one device at a time.

I have used lots of these things at work, and FTDI is the best solution out there.

-j


It's a serious problem to consider...  I have sent mail to silabs with your comments. We might stick to FT232 if there is no news for CP2102 Mac OS support.  Or, is there other USB-UART chips could be a better alternative? Like PL2302 for example. It'll help reduce the final price remarkably.

Thanks smiley-wink

Combine from the other duplicate thread:

1. Align the header with 2.54mm grid.

Related discussions: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1206626508

Place an second row of header align to standard grid. So it will be compatible to existing shield and your proto board. Both of the headers will be soldered, or either of them.

 
Is it possible to do ? What solution do you have ? Headers with a 1.27mm pitchs ?
 
Quote:
3. Possibility for USB HID support.

Great ! Worth trying, I think.
 
Maybe you could include the side switch instead of the jumper for selecting between USB and external power.
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1218817652
Maybe the same switch for the auto-reset.
 
 
Nice update to the board family, in any case ^^

Easily.  I suggested this ages ago in the bugs and suggestions forum.  Imagine the standard Arduino Diecimila board.  Now along the digital IO connectors put a second row of IO connectors 0.1 inches closer to the edge of the board (you may need to make the board 0.1 inches wider).  The second row can easily be attached to the first row on the PCB (each pin is just a 0.1 inch jump away), but now on the second row, correct the spacing to 0.2 inches between the two headers.
 
You can connect a shield to the old connectors or a standard perf board to the new headers.

Arduino is great, so does the team. While enjoying Aduino , we found there are several inconvenices could be improved. People in Arduino forum has some discussions in improving it. Thanks to open source, freshman like us could take gut to try.

Albert and I have spend some time for a new board in fixing the obvious drawbacks and made some improvements. The new board will base on Diecimila, and 100% compatible to its shields, cases, software… You should have no problem adopting it to your current projects. The changes are:

1. Align the header with 2.54mm grid.

Related discussions: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1206626508

Place an second row of header align to standard grid. So it will be compatible to existing shield and your proto board. Both of the headers will be soldered, or either of them.

2. A jumper to disable auto-reset.

Related discussions: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1213719666

DIP switches.

3. Possibility for USB HID support.

Related discussions: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1172471904
We want to use CP2102 instead of FT232, it's smaller form factor, cheaper and it has a stronger brother F32x & F34x. These USB MCU F32x could be programed to many USB devices easily. Example for HID:http://www.cygnal.org/ubb/Forum9/HTML/001381.html

4. Make it flat

We want place a proto board directly onto Arduino… The B-type USB, power jacks are standing in the way.

Alternatives will be mini-USB,  ext power pin plug. Moreover, the reset button is moved to the edge of the board, so that we can reset easily while bearing shields.

5. Two extra Analog - ADC6, ADC7

6. 3.3V and 5V switch

7. Full UART pin out

8. Other trival improvement

9. Reorganize the PCB


The v1.0b PCB and Scheme will be released very soon, under Creative Commons Attribution-ShareAlike 3.0 License. Suggestion sincerely welcomed! It's not an official version, and we would like to call it Seeeduino ^^

HULK - It's the right datasheet you have found.

While we test the LCD, it's not displaying good for the spinning lines. I didn't change the settings, but added delays as discussed in some posts here until we see it work fine. FPS=6

Thanks for the review:)

This article on iPod clickwheel explains the principle of how capacitive sensing works. But how would I go about connecting one of these to Arduino?
Should I simply abandon the idea?  :smiley

Thanks!

Interesting~ I was trying to locate some capacitive sensor...

The connection should not be a problem, there are jackets for it.

Thank you so much Eric smiley-wink So that's the best option I have... I have sourced for some UART mux chips... but too much for some simple controlling.

I'll try it out and post here.
42  Forum 2005-2010 (read only) / Interfacing / get more UART from Arduino on: August 23, 2008, 10:19:13 pm
hi Guys:
Is there any hardware solution to increase the UART port number on Arduino? I want to control a serial LCD, a ultra sonic sensor and still keep connected with processing on PC. It seems resource consuming using a soft UART.

Thanks~

This is Eric from Seeed studio, we are working on products in direction of an modular home automation system, more products like smart outlet, relay shield, wireless utility meter and etc will be published soon, the project is of great reference to us.

If possible, we would like to building our new products around practical needs like this, please let us know what could be done to make your project easier smiley-wink

Keep up the great work!
