Arduino driver issues

[jslate1980]

Hi

 

We seem to be having a driver issue with connecting uno boards. When running code we get this error: avrdude: ser_open(): can't open device "\\.\COM3": Access is denied.

Is there anything that I need to do to get it communicating properly for students?

I'm no expert on domain controlled computers but how were the Arduino drivers installed - does it make a diff if you logon with local machine admin credentials?

The arduino drivers are a bit of a pain to install.

 

Steps that I took.

Download the latest drivers from arduino.cc (as these will also contain the drivers for the arduino.org boards)

Extract the security certificate for the drivers and put it in the trusted publishers store in group policy.

Repackage the installer using an msi builder (I used exemsi) and configure it to use the /S switch for silent install

Distribute via software installation.

 

Make sure that you select the correct COM port and make sure that you also select the right board, via Tools >> Port, and Tools >> Board
