Hi everyone I have a question to ask about. I face a problem about the port number it doesn't show up in Arduino IDE but in Device manager it shows. I tried to reset board (Arduino Uno Rev3), use different USB cable, reinstalled the Arduino IDE, restarted PC but still there's no improvement and in Arduino IDE the port section is greyed out.
Is the board plugged into the PC?
Yes it is connected to PC. The problem here is that in Device manager under Ports there's a port number shown up but in Arduino IDE the are no port discovered.
Ue screen grabs, NOT photos. I can't see those. Get this from your PC
notice the Show all ports box is checked.
Try selecting your board first.
I did Arduino Uno
It's not showing in the picture.
- Under ports? Or somewhere else?
- Any yellow triangles?
- With name "Arduino Uno (COMx)"? Or just as "something (COMx)"? Or ... ?
- Which version of Windows?
Did it work in the past? If yes, what is the history of the board?
- What was the last project that you worked on?
- And what is the project when it started to fail?
I use Windows 10.
I haven't worked with any project.
No it haven't work in the past.
On the picture provided it wasn't showing but for now I selected the board and try to find the port number.
I asked four initial questions; you only answered one.
- Under Ports in the Device manager there's a port number but in Arduino IDE there's no port number discovered.
- Haven't seen yellow triangle yet
- There's no name mentioned above
- Windows 10
Basically it haven't worked in the past.
It will probably be something in the line of "Serial port (COMx)" in which case you have a clone.
Right click on the device in device manager, go to the details tab and check hardware ids.
Below are some options for the VID and PID (there are more options)
- 16U2 (real Uno)
VID 2a03, PID 0043 - CH341
VID 1a86, PID 7523 - FTDI
VID 0403, PID 6001
For (1) and (3) you do not need to install the drivers, they are installed when you install the IDE. For (2) you probably did install the drivers else it would not show under ports.
The only thing I have heard about (for (2)) is that Windows might think that it's a Bluetooth device. You can temporarily disable Bluetooth to test.
Please follow these instructions: Arduino IDE 2.3.2 endless loading Windows 10 - #2 by ptillisch.
Post the result here; if it exceeds 120000 characters, copy/paste the output in a text file and attach it here. This is getting into territory that I'm not familiar with but it might revel something.
