Arduino MICRO disapears

Projects Programming

Hi all,

I was not able to finde a special MICRO-Board ... Please move me if necassary.

My Arduino MICRO is something mad.
On connecting the "windows BLOP" indicates there is something new.
After one second the disconnected-sound comes up.

On pressing the RESET button on PCB, Arduino will connect again and appears for a few secs at Windows device manager (and USB treeview) and hide away ...

I guess the guy is dead somehow and a new board is ordered already.

BTW. The blue light is on, while it stays connected.

Any idea ...?

I too had this problem..... I fixed it several times (repeated) make a small sketch and
start compiling it...
press the Micro reset button before it finishes compiling
and if you are lucky it will upload...

repeat as needed... sometimes 20x for me, then load your original program

Perhaps your board does not have a proper bootloader programmed into it? Some third-party Arduino boards come with the FLASH competely blank, or programmed with some useless sketch, and no bootloader.

Thanks for your ideas.

I tried more than 20 times to compile andy quickly press the reset just before upload starts.
Unfortunately without success.

The MICRO is original Arduino, means I supose all bootloaders must be available.

I use this method to upload using the bootloader. Arduino Leonardo, Pro Micro, and Micro all have the same microcontroller so the procedures applies to all. Also the procedure does not require using the XInput library. I suggest uploading a blink sketch to recover the board.

Hi,
thanks for the link, I will check it.

Please note the connection via USB is not stable.
The windows "blop sound" indicates a connection.
After a few seconds th econnection is lost.

It is a tricky game to choose the right board and COM at the IDE.

Perhaps your board has a sketch running that messes up with usb

Hi,
What version IDE are you using?
What OS?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia: :santa:
