Arduino IDE not connecting to microcontroller

linux-howto

http://askubuntu.com – I get this error when trying to connect to an Arduino through a USB serial connection. I'm using the Arduino IDE 1.0.1 and the 64bit version of Ubuntu 12.04. This has been a reoccurring problem since 10.04 and happens to a few other programs that use a serial connection too. I have no problem getting serial data from the Arduino using Python or Screen. The Arduino IDE seems to work just fine otherwise. processing.app.SerialException: Error opening serial port '/dev/ttyACM0'. at processing.app.Serial.<init>(Serial.java:178) at processing.app.Serial.<init>(Serial.java:92) at p (HowTos)

Stories similar to Arduino IDE not connecting to microcontroller

I'm on linux and for some reason I can only use the serial port while screen is monitoring it. When screen is not running, the python code doesn't crash or something. The arduino just doesn't respond. Is there something I'm missing?

Renaming serial ports in unix 51 weeks 6 days ago

Hello everyone, this is my first post and I am by no means a unix expert, so I hope I explain my issue well.

I'm on a mac (mac mini), 10.7.

My question is about serial port names.

I apologize in advanced if this is in the wrong section.

I have an arduino hooked up to a xubuntu box via a usb/serial connection. A perl script interacts with this arduino and all is well on that front except for the constant renaming of the arduino /dev file.

I am testing Digitus USB -> RS232 converter, which is using Prolific PL2303 chip. The aim is to connect to GSP module U-blox LEA 6H.

Whenever I connect an Arduino via USB I lose mouse control after 5-10 seconds. I must reboot to regain mouse control.

This occurs whether the arduino is powered via USB or externally, also the arduino is not sending any serial data.

I am running fedora 12 64bit, and this issue did not occur in Fedora 11.

Good Day! I don't really know how to ask the right question but I'll try to explain the situation thoroughly.

Im trying to make a 12-button keypad for android phones, I used a Mini Clone version of arduino Atmeg168, a 3x4 keypad, and a bluetooth shield, honestly, I havent really successfully show up all the alphabets.

I am actually using Cygwin, but it is my understanding that it responds to Unix commands so hopefully I am in the correct place.

I have an Arduino hooked up via USB to my LapTop for data reading.

I want to be able to simultaneously be able to output the serial port data to the shell for my viewing and also save all that data as a text file.

Is there a command I can use to do this?

I am creating a python application using twisted which reads lines from a serial port. In order to (unit)test that app without having to connect an actual device to the serial port (also on pc's without an actual serial port) I would like to create a python script/app that sets up a virtual serial port and writes to it, so the twisted app can connect to the other end of the virtual serial port and

Serial Forwarder and Matlab 6 weeks 3 days ago

I am trying to read data from Serial Forwarder in Matlab and then save it into text file. When I use the command: java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB2:telosb in the terminal I get the data there.

Then in Matlab I have tried: s = serial('/dev/ttyUSB2','BaudRate',57600,'DataBits',8); fopen(s);

and it seems to work just fine.
