I just received my new Zumo 32U4 (pre-assembled version) today. I’m following the setup directions (at https://www.pololu.com/docs/0J63/all) to the letter. I’m on Windows 10 Pro.
Step 9 in section 5.2 (Programming using the Arduino IDE) says to specify the port using the Tools->Port menu in the Arduino IDE (version 1.8.2) , but the menu is grayed out!
Also, when I go to Device Manager, there is not section for “Ports (COM & LPT)”. This seems related.
The Arduino IDE has a text in the bottom right which says “Polulu A-Star 32U4 on COM1”, so I thought maybe it know the COM port and doesn’t let it be configured. So, I tried Uploading the Blink example anyways, but get the error: “Couldn’t find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board’s reset button after initiating the upload.”
I did try the rest button on the Zumo 32U4 but that did not work.
At this point, I’m stuck. Based on the amount of people on the internet asking about (1) COM ports in the Device Manager, and (2) the Port menu disabled, I deduce this is a pretty common problem. Unfortunately, I can’t find a straight forward solution.
Help me, Obiwan, you’re my only hope.
