Can't upload onto Itsy Bitsy 32u4

Post by alphax1987 »

Im currently trying to upload code onto the Itsy Bitsy 32u4 however it is constantly stating avrdude: ser_open(): can't open device "\\.\COM#": The system cannot find the file specified. I don't know what to do and I already tried to change the wire that is connected to the Itsy Bitsy and changing the COM number.

Are you working with code that uses the serial monitor? On a 32U4 that can interfere with uploading code.
2 things to try:
double tap reset and check if it goes into another mode
or hit reset exactly on the moment the compiler wants to start with uploading.

By wire, do you mean USB cable?
