Arduino Error Opening Serial Port Port Busy
3 Karma: 0[add] Arduino rocks Error opening serial port '/dev/ttyUSBx' on Ubuntu Dec 03, 2008, 03:42 pm Hi!I'm suddenly having problems uploading/communicating with my Arduino
Error Opening Serial Port Windows 7
board via the Arduino Java IDE.. The strange thing is it happened after working for 2 days straight..I was editing a program, continously uploading and testing it, when I clicked the "Serial Monitor" button so I could debug (which had worked fine just minutes ago).First I get a lot error opening serial port '/dev/ttyacm0' permission denied of weird char's, like you'd get trying to Serial.print a non-alphanumeric byte (although it was an int) - then, after fiddeling with the Serial rate from the IDE (while the Arduino program was still running), I got an error.Ctrl+c, ./arduino and "Upload to I/O Board"... Still get an error.I've tried rebooting Ubuntu, reinstalling the software, removing all components and reprogrammed the Blink-example with my Windows machine (which worked - so I doubt the board is damaged).Below is the full error message. I'm 100% sure the usb-device is correct.processing.app.SerialException: Error opening serial port '/dev/ttyUSB0'. at processing.app.Serial.

Shaaban 614 To be able to help you it would really help to know your development environment (what OS are you working on, how are you connecting to the serial port, etc.). The message suggests that another process using the serial port, it could be as simple as need to close and reopen your terminal emulator. –dlu Nov 26 '15 at 20:01 Im using windows 8.1, and im connecting to the serial port via usb. –M. Shaaban Nov 26 '15 at 20:04 How are you connecting to the serial port (what software are you using to received the serial data)? I don't do much with Windows, but I think the problem that you're having is that your terminal emulator is expecting to see the data on your COM1 port but you're actually transmitting the data over USB and a virtual serial port. The serial monitor in the Arduino IDE picks up the serial port from the setting in the menu Tools > Port (which is also used for your upload), but other programs will need it to be explicitly set. –dlu Nov 26 '15 at 20:09 the software is built in the arduino IDE. I edited the post the code is not uploading, only compiling. &nd

The rest of the name can change. Judging by the name, it looks as if the serial port may be used by an EV3 block (Lego robot.) jim_reed 2015-04-20 16:37:09 UTC #4 I got it figure out today. It would not work on my Macbook Air but worked on my iMac. The MacBook did not have the "tty" port but the iMac did. Weird deal. chris101 2015-04-20 20:00:06 UTC #5 That is weird. I notice that every now and then, the port will not appear. When I quit the Arduino IDE and restart it, the port (almost always) re-appears. Some times I need to restart a couple times. Anyway, I'm glad you got it working. bibi 2016-01-07 23:18:01 UTC #6 Hi!I have managed to solve the problem: I think the problem occurs because I have first launched Arduino software from the arduino folder (without installing it). So I have downloaded the latest Arduino software version(it's .exe file) and I have installed it into my computer. This has created "Arduin
