Hello,

I am new here but am struggling for two weeks now with updating the motorshieldv2 library to the arduino... I have tried every possible solution online but nothing worked and so I was hoping somebody could help.

When I connect to the Arduino just by a=arduino() it works, also with specifying the com and board type. Moreover it still works if I include the 'servo' library... but when I try uploading the adafruit/motorshieldv2 library it gives me an error: Cannot program board Uno (COM3). Please make sure the board is supported and the port and board type are correct. (by the way the workspace was cleared before launching the last command in the picture below)

I am using Matlab R2015a with windows10 and the hardware support package for arduino is installed.

This probably has a very simple solution and i will probably feel very stupid but I really need this to work so I can start the real work :)

thank you in advance

I encountered this problem today. I tried a lot of possible solutions, but no success. However, after I switched to a different computer, the motor shield library then can be uploaded to the Arduino board. I hope this will help.

Can you specify what PC config you had on the comp that didnt work and on the comp that did work? Windows 10? 8?7? 32bit?64bit?

I have this problem when my Arduino is in 2 of the 4 USB slots on my laptop. Changing the USB slot to one of the other 2 slots preserves the same COM port, but it does not try to update the Arduino code, and everything works fine.
