Well, dang. I took the left enclosure off, and I’m pressing the reset button, but I can’t get my keyboard to work again at all. I’ve tried several different orders of operation for hitting the reset button, hitting the upload button, and hitting the prog button – it all comes to naught though.
Procedure:
- in Arduino GUI, go to File => Examples => Keyboard IO => Model 01 Firmware
- With left enclosure removed, depress then release the little white button. The red light behind the prog button comes on.
- Hit the right-arrow in arduino UI that means 'upload’
The red light for the prog key goes out; the blue light under the LED key goes on briefly, then goes off.
about another 1min goes by, ending with the selected serial port does not exist or your board is not connected.
Complete output from upload:
Sketch uses 18972 bytes (66%) of program storage space. Maximum is 28672 bytes.
Global variables use 1941 bytes (75%) of dynamic memory, leaving 619 bytes for local variables. Maximum is 2560 bytes.
Low memory available, stability problems may occur.

avrdude done. Thank you.
the selected serial port
does not exist or your board is not connected
and yet, i can’t send keypresses; the one thing that seems to work is changing LED mode.
How can I get back to factory state? I saw @jesse’s thread Flashing problem on Ubuntu (SOLVED) but that is both off the cuff and perhaps linux specific.
I’m using OS X 10.13.1.
