I went to bed last night after playing around on Arduino, saved, exited, unplugged, locked my computer, and went to sleep. I woke up and Arduino IDE will no longer identify either of my Arduinos (an uno and a mega 2560) on either of my two functional cables. I tried it on my laptop and everything is fine. I checked the device manager and the Arduino appears fine in the appropriate category. I tried multiple USB ports including USB 3. Double-clicking the reset button did nothing What the hey?
Hi @jdel. I'm sorry about the problem with the board identification in Arduino IDE.
Please try this:
- Select File > Quit from the Arduino IDE menus.
- Start Arduino IDE.
- Plug the USB cable of your Arduino board into your computer if it is not already.
Does Arduino IDE now identify the Arduino board?
my 2.0.3 ide keeps on asking to select com port and under tools the com option disappeared and the IDE won't quit when tap the X icon in the upper right hand corner and under the file menu the Quit option doesn't work either!
I'll provide instructions you can follow to force quit Arduino IDE:
- Open the Windows "Start" menu.
- Search for
task manager - Start the "Task Manager" app.
- Find "Arduino IDE" in the list of processes and click on it.
- Click on "End task" on the processes toolbar.
Arduino IDE should now exit. - Restart Windows (this is an option accessed via the power button on the "Start" menu) in order to restore the system from any ephemeral bad state that might have caused the Arduino IDE application hang.
- Start Arduino IDE.
