Still Having Problems?
Feather HELP!
My Feather stopped working when I unplugged the USB!
My Feather never shows up as a COM or Serial port in the Arduino IDE
Ack! I "did something" and now when I plug in the Feather, it doesn't show up as a
device anymore so I cant upload to it or fix it...
I can't get the Feather USB device to show up - I get "USB Device Malfunctioning"
errors!
I'm having problems with COM ports and my Feather 32u4/M0
I don't understand why the COM port disappears, this does not happen on my Arduino
UNO!
I'm trying to upload to my 32u4, getting "avrdude: butterfly_recv(): programmer is not
responding" errors
I'm trying to upload to my Feather M0, and I get this error "Connecting to programmer:
.avrdude: butterfly_recv(): programmer is not responding"
I'm trying to upload to my Feather and i get this error "avrdude: ser_recv(): programmer
is not responding"
I attached some wings to my Feather and now I can't read the battery voltage!
