1  Forum 2005-2010 (read only) / Development / Ipod dock compatible Arduino Music shield on: May 20, 2010, 10:42:33 pm
I love music, so i love this coming new product from Seeed Studio. It is a ipod/iphone dock compatible shield, can be work on Seeeduino v328, Seeeduino Mega and Arduino (Atmega 328 version).  It is based on VS1053b,  you can play variety of music format with this shield, even record sounds. The most interesting thing is, it has the very same 30 pins connector as ipod does have, and we make it possible to use the shield on any ipod compatible docks. You can output music to a external speaker, use the Play/pause, next song/previous song button on the dock or remote controller. The shield can be even powered by the dock, and all this feature makes the shield working as a real player now.



This product will be available very soon. If you have any suggestion to it, just leave in comment.

A few wrap-up on the DSO Nano v2 open source fruits!

Free open tool chain

Now Jerry have finished migrating from IAR to GNU tool chain, there is no longer 32Kb code limitation or commercial license concerns! Please join the discussion and try the new compiler from our forum: http://www.seeedhttp://studio.com/forum/viewtopic.php?f=12&t=1262 . Thanks to the help from everybody, especially tormod for providing the new dfuse tool working natively under linux!



Improvements:

  • Proper three phase sampling (pre-fetch, trigger-fetch, post-fetch) guaranteed never to miss infrequent events
More efficient screen update (10-100 times faster than version 2.5e)
Eliminate all flickering and stuck pixels
Code is re-written to allow full compile time optimization (much faster and compact code all over)
A bug in Vrms calculation is fixed (Vrms is incorrect in 2.5e)
A number of overflow bugs have been fixed (calculations for large time/div settings)
Scan has been replaced with a proper continues real-time scan mode
Configuration profiles can be saved to /restored from SD card or flash (default power on settings).
Wave data (reference signals) can be saved/restored from SD cards
Screen capture can be saved to SD bitmap files
A number of issues with incorrect SD card support and file handling in 2.5e have been fixed
FIT mode is implemented as a function
The full captured signal buffer (3000+ points) can be panned left right for further analysis
A more relevant collection of data is selected for display on screen
A more relevant selection of measurements
Simultaneous view of all measurements
Use proper ISO abbreviations (e.g. milliseconds is “ms” not “mS”)
A completely redesigned user interface (no annoying blinking or color abuse)
Support two step calibration (offset and range)
[/list]

Download at http://www.seeedstudio.com/forum/download/file.php?id=299 and take a try! Thanks again BenF, you know much better what people want from the firmware!

Finally, some new updates of DSO QUAD!

We have finished mold design and moving to trial batch now! They might be ready late this month or early Dec. A few beta units will be open for pre-order. Check out the infant photos of the prototype. The final product will be using different material, expect something neat .

We will use 328 on our next version of Seeeduino. Now we have some problem on getting the chip. Before we can get lots of Atmega 328 with nice price,we will contunue using Atmega 168 on seeeduino.
10  Forum 2005-2010 (read only) / Development / Seeeduino V2.12 on: June 01, 2009, 05:47:19 am





What's new for v2.12?
      
       [ch9679] Zero external power consumption when switched off.
       [ch9679] Stronger Switches.
       [ch9679] Second power supply for 5V direct input. [Caution] USE 5V ONLY!
       [ch9679] 150mA driver capacity under 3.3V.
       [ch9679] 1.0mm slim PCB for lighter weight.
       [ch9679] Extra row reserved for pin headers.



Overview

Seeeduino is Arduino compatible board. Its design is based on Diecimila scheme, 100% compatible to its existing program, shield and IDEs. On the hardware part, remarkable changes are taken to improve the flexibility and user experience.


Summary

Microcontroller      ATmega168
Operating Voltage      5V/3.3V
Input Voltage (recommended)      7-12 V
Input Voltage (limits)      6-20 V
Digital I/O Pins      14 (of which 6 provide PWM output)
Analog Input Pins      8
DC Current per I/O Pin      40 mA
DC Current for 3.3V Pin      50 mA
Flash Memory      16 KB (of which 2 KB used by bootloader)
SRAM      1 KB
EEPROM      512 bytes
Clock Speed      16 MHz



1. Duplicate digital IO to 100mil grid for prototype board compatibility
.
Adding an second row of header align to standard 100mil grid, so it will be compatible both to existing shield and to a cheap 100mil grid prototype board. By default, the traditional IO is soldered instead or new headers, and you may add the new header yourself.

2. Shrink componets height below female headers.
Seeeduino is made as flat as possible, even the crystals are SMD version. So we may put your soldered prototype board onto it with less worry.

3. Easier access to buttons and switches.
All buttons or switches are moved nearer to the edges, so we may reach them easier under the shield or from the wire forests.

4. Change Type-B USB port to Mini USB.
Consideration for dimensions.

5. Replace 3.5mm DC power Jack to battery 2 Pin plug.
Soldering the 3.5mm DC power jack is usually the most difficult part, and we think it's too giant. Maybe a battery pack is more convenient than power adapters? Don't worry about abandoning your 12V adapter, we have a simple convertor.

6. Reset and power indicator near RST button.
We use one LED for power indicator and the other for reset (it will also lid when downloading programs).

7. Auto-reset selection.
Auto-reset is a great feature loved by many. But sometimes we would also like to disable it in production-like mode.

8. 3.3V Operating Voltage selection.
The Vcc could be selected by a switch, for making life easier dealing 3.3v devices.

9. Pin out UART for FTDI232 bit-bang operation.
At least you can burn bootloader without an ISP cable now (Plz refer to Kimio's detail tutor: http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html)

10. Pin out 2 extra ADC.
Why not? There are spaces smiley

11. Pin out for I2C and sensors.
Easier connection to I2C and sensors by a bended femail header.

12. Second power supply for 5V direct input.
Sometimes we would need to apply 5 VDC to Seeeduino either for higher power effeciency or just because having 5VDC in hand. Now you may use these 5V supply to directly power Seeeduino. [Caution] USE 5V ONLY!

13. ReRoute PCB
SMD version Atmega168 give us more space to route, so we carefully rearranged them for us to see the flow more clearly.
Please visit the supporing thread >>here for suggestions on next revision.

14.Easy Uart connection

15.Extra row reserved for DIY pin headers.
You may now use female, male, or DUAL male headers on these pins as well.

16.Extra 3.3V regulator for higher current supply
It's dedicated 150mA now, rather than 50mA supplied by FT232.

It looks nice. I like the color of this board.
13  Forum 2005-2010 (read only) / Development / 4*4*4 Rainbow Cube, the ultimate form on: December 07, 2009, 06:44:00 am


It's a long time development for the new cube, we finally have some satisfying result now. Here is the final prototype, almost the same as releasing version. You will see we changed to 8mm foggy RGB LED instead of SMD ones,  increased the dimension beyond Rainbowduino. Most of the assembly difficulties are bypassed by the slim PCBs,

You will be able to get kits from depot soon, with or without Rainbowduino. : )

To: mowcius

Sorry for the wrong spelling of Service...

Normally you get 10 tested boards with 30USD but if you choose Open source option,(it means we will keep 5pcs and sell them, all source file will be published online) you saved 12 USD by this . You can also choose No-Etest option to save another 5 USD.  So the the minimum cost for 5pcs PCB (5cm X 5cm, 2layers) is 13 USD.


to:florinc

You can say it again. We are planning to provide those services. Just give us a little time.

15  Forum 2005-2010 (read only) / Development / Maybe the cheapest PCB service? on: September 17, 2009, 02:57:57 am
This is definitely a good news for developers. Seeed Studio decided to cut down the price of Propaganda PCB service . The new price will start from 13 USD/ 5 PCs.  (2 layer, 5cm X 5cm max, no E-test, Open source PCB). See below for more.



We also provide 4 layers PCB service start from 105 USD/5 PCs.(Open source, No E-test).

Any question please send mail to Fan@seeedstudio.com  .
