Topic: Arduino Diecimila, Arduino 0009 and OS X (Read 655 times) previous topic - next topic


I'm trying to get my Diecimila board communicating with my OS X system and don't seem to be having any luck.

I first tried just loading the usb driver that came with Arduino 0009, rebooting, plugging in the Diecimila and launching Arduino 009. Unfortunately, the usb serial driver wasn't listed under Tools -> Serial Port.

So I looked through the boards and found the posting at http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1143197735, followed the instructions to re-install and still the usb serial driver wasn't listed.

So now I'm stuck. I'm not sure what I need to do in order to debug this and get the board talking with my system. Any suggestions?

There is a slightly newer version of the drivers on the FTDI website: http://www.ftdichip.com/Drivers/VCP.htm.  You might try uninstalling the ones that came with Arduino and installing those.

What version of OS X do you have?  Intel or PPC Mac?  In the System Profiler, when the board is connected do you see FT232RL USB UART under USB?  If you open a Terminal and do:

ls /dev/tty.*

What do you see?


I've tried the latest FTDI drivers, version 2.2.7 and have the same results.

I'm running on an Intel MacBook Pro w/ 2GB memory, 120GB disk and OS X 10.4.10.

System profiler shows:


 Version:      6.00
 Bus Power (mA):      500
 Speed:      Up to 12 Mb/sec
 Manufacturer:      FTDI
 Product ID:      0x6001
 Serial Number:      A4001tot
 Vendor ID:      0x0403

And /dev/tty.* shows:

/dev/tty.Bluetooth-Modem        /dev/tty.Bluetooth-PDA-Sync     /dev/tty.Peter-1                /dev/tty.usbserial-A4001tot

As you can see, there's now a tty.usbserial entry under /dev/. This wasn't there last night when I was trying to get the communications working. I'm a bit confused.

But I did just upload the Blink example sketch and its running on the board now. Wahoo!
