On Monday, January 17, 2011, I visited the local post office to see if my package from Seeed Studio has arrived. Luckily, it did, and so I commuted to SM Megamall, to visit Alexan (my electronic parts supplier) and get what I needed before I start working with my new toys.
As you can see, I made my own mount using the bottom part of the white casing. I used my needlenose pliers and hot glue gun. I wanted to be able to close the casing, in the event I wanted to transport it.
Very nice. I really like the Seeeduino boards, they have lots of features missing or different from the Arduino standard. I own two of their Mega boards.

Thanks! I just the only one... I do have an Arduino UNO in my Seeed Studio shopping cart... I'm hoping to meet other Seeeduino users...
If you do ever get a Seeeduino mega board, you will find that it wires up 16 additonal I/O pins from the mega1280 chip that the Arduino mega board doesn't even wire up to any connectors.

On that note, how do you use the extra pins in the Arduino environment?
Do I have to add a new board definition?

Unfortunately because the Arduino team didn't break out those extra 16 pin, they also didn't define them in the pin mapping core library. So commands like digitalRead() and digitalWrite() won't access those additional pins. However one can access them using direct port commands. The method is shown here for 328 I/O ports:

It would be nice if someone could flesh out the arduino pin mapping routines to make use of these additional mega1280 pins, but it's well beyond my capabilities and I don't suspect the Arduino team is willing to support pins for boards they don't manufacture.
