Ok so I have spent three days trying to connect my crius se 2.5 board and searched for hours on here for an answer to no avail. When I try to upload the sketch i get the following error:
avrdude: ser_open(): can't open device "\.\COM1": Access is denied.
I have tried changing the com ports, uninstalling/reinstalling, rebooting.... I am lost and quite frustrated. Any help would be greatly appreciated!
I am running this board on a quad x multicopter My OS is Windows 10
