I've just received my first arduino platform. It's a DCcduino board (a clone of Arduino Uno). As I had some difficulties to have it recognised by my MacBook, I decided to share its drivers. This card has a CH340 USB-to-serial chip. You can find drivers for this chip on the web site of the chinese manufacturer, here :http://www.wch.cn/downloads.php?name=pro&proid=5
Or download it directly from my Google Drive. The archive contains drivers for Mac, Linux and Windows platforms.

How to open serial port (using rxtx)
Ok. So here’s a brief explanation of how to open serial port in Java using rxtx.
First of all, you need to get the serial port’s ID
Then, you’ll need to ask the OS to give the serial port ownership to you.
The “Demo application” string is the application’s name. The rxtx will pass this value to OS as the application name who ask the serial port ownership (I think there’s some Unix command to view which application hold which system resource.I need to dig more on this use
lsof /dev/<your serial device>
to see which application that holds it. But I should remind you that “Demo application” string won’t come up using lsof
or ps -ax

The 5000 value is the timeout value that is given to the system to release the port (5000 ms = 5 seconds). Nokia lumia 635 sim unlock. If the current owner of the serial port doesn’t release the serial port within 5 seconds, rxtx will throw an

Lastly, before you can read or write to serial port. You’ll need its inputstream and outputstream.
So, here’s the complete example of the method to open the serial port
