Topic: *HELP NEEDED* Sketch will not upload (feather adalogger) (Read 592 times) previous topic - next topic


Hi! I am using a feather adalogger. I have uploaded code many times to it successfully, but while using it today, it stopped working. I am not able to upload code to it.
The code I am using compiles with no errors.
When I hit upload, I am greeted with the following error:

avrdude: ser_open(): can't set com-state for "\\.\COM3"
An error occurred while uploading the sketch

I have tried:
3 different COM ports
2 different cables
restarting my laptop

This is an urgent issue; Is there any ideas as to why this is not working?


Is it still recognised by Windows? What does the device manager say?
If you understand an example, use it.
If you don't understand an example, don't use it.
