(CDeviceRS232::OpenSerialPort) ERROR: No such directory

Post by bub4 »

Hello All,

Finally I got my Arduino Uno and all LED stuff to setup my boblight.
Thanks adafruit for such a quick delivery to Germany!

I got the LEDs working as Abmilight with Processing Tool and the standalone solution.
So far so good.
I like to use this with xbmc and boblight to avoid the black bar "problem" at some content.
So I setup a boblighd on raspberry to serve the Mac over network.
Boblighd connection is just fine between Mac and raspberry...

I currently stuck at the communication to the serialport which should make the LEDs shining:
http://BANNED.com/289V7bKd
-> (CDeviceRS232::OpenSerialPort) ERROR: ambilight: /dev/tty.usbmodem641: open() No such file or directory
I've no idea what the root cause of this is.

I'm running OS 10.7.5 on a Mac Mini 2010 and the serial port definitely is correct @tty.usbmodem641.

When I ask google I found some issues that 10.7.4 doesn't display the serial ports correct.
https://github.com/voodootikigod/node-s ... /issues/83
Could their issue also apply to mine?

I'm not a skilled coder, therefore I need some support, I'm afraid.
Does anyone have some experience with MacOS + Boglight + Arduino?
I really go crazy at the moment :cry:

I would - very much - appreciate some help from the Pros.

Thank you for your help, and please apologize my bad english...

The serial port number can change when you plug in a new device. Check the Tools -> Serial Port menu to make sure you've selected the right one.

Hi Mike,

I checked both, in tools and Mac Terminal as well.
There is no other usb device plugged.

What I was wondering:
"If you're using the Arduino Uno or Arduino Mega 2560, a dialog box will appear telling you that a new network interface has been detected. Click "Network Preferences...", and when it opens, simply click "Apply". The Uno or Mega 2560 will show up as "Not Configured", but it's working properly."
-> this was mentioned in the getting started guide of Arduino but it never happened.
I was indeed able to programm the arduino and it works but could it be possible, that the board isn't "fully" recognized by my Mac?

It's possible that something went wrong in the recognition process.

If you open System Preferences and go to the Network pane, you should see a list of interfaces the OS knows about along the left side:
interfaces.jpg
interfaces.jpg (40.38 KiB) Viewed 210 times
You should have one for "USB Modem".. that's the closest match OS X has for an Arduino Serial connection.

Do you see something similar on your machine?

Hi Mike,

Yes, it does. There is an USB modem displayed.
I guess my problem this is something Mac related. I've found lots of problems reported under 10.7.5.
Upgrading is not an option I'm afraid :/

I'm thinking about having a second standalone scetch, which has a smaller frame grab-window for the super wide screen contents (21:9).
Could you, or anyone else, let me know how to figure this out in processing?

Thank you!!

Edit: antother problem is, that the Mac doesn't startup, if the arduino is plugged. I have to use an active USB hup as workaround.
-> OS 10.9 startsup properly with the arduino attached...
In addition I'll try if boblighd works with 10.9

Try deleting the existing modem and plugging the Arduino in again. That should trigger a new round of device recognition on the Mac.
