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.

(Port busy) up vote 1 down vote favorite Im using the arduino Micro pro to read the data out of a http://askubuntu.com/questions/185805/arduino-ide-not-connecting-to-microcontroller temperature sensor (lm35). The program is compiling and NOT uploading, but when I try and open the serial monitor is says: Error opening serial port 'COM1'.

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 http://arduino.stackexchange.com/questions/18153/error-opening-serial-port-com1-port-busy 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. –M. Shaaban Nov 26 '15 at 20:18 COM1 is usually reserved for the built in serial port in the computer. Your USB serial port is more likely going to be COM3 or COM11, or even COM23 rather than COM1. Make absolutely sure you have the right COM port selected, and that you have installed the right serial drivers for your board. –Majenko Nov 26 '15 at 20:19 | show 3 more comments 3 Answers 3 active oldest votes up vote 3 do

This is a tricky bug cause you cannot change the baud rate until after you open a serial monitor, which you cannot do. I resolved the bug by editing ~.arduino/preferances.txt and changing serial.debug_rate=38400 to serial.debug_rate=9600 error message processing.app.SerialException: Error opening serial port '/dev/ttyACM0'. at processing.app.Serial.(Serial.java:178) at processing.app.Serial.(Serial.java:92) at processing.app.SerialMonitor.openSerialPort(SerialMonitor.java:207) at processing.app.Editor.handleSerial(Editor.java:2481) at processing.app.Editor$17.actionPerformed(Editor.java:665) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.AbstractButton.doClick(AbstractButton.java:376) at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:833) at javax.swing.plaf.basic.BasicMenuItemUI$Handler.mouseReleased(BasicMenuItemUI.java:877) at java.awt.Component.processMouseEvent(Component.java:6505) at javax.swing.JComponent.processMouseEvent(JComponent.java:3311) at java.awt.Component.processEvent(Component.java:6270) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4861) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4492) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at ja
