Troubleshooting

If the serial port doesn't appear, see above.

Strange blinking: Did you attach the LiPo battery?

Bricked the board? if you choose the wrong board and upload this might happen. solder on the ISP plug and burn the bootloader. the files is in the core.

for linux:avrdude -P /dev/ttyACM0 -b 19200 -c avrisp -p m32u4 -v -e -U flash:w:Caterina-fio.hex:i

Pins:

A0 ( you can also only write 0) -> D18

A1 ( you can also only write 1) -> D19

D2 (2)

D3 (3)

D9 (9) also connected to LED2

D13 (13)

the middle i don't know. maybe charge state?

RX (0)

TX (1)

Timers

To change the prescaler of the timer connected to Pin9 (sound output)

TCCR1B = TCCR0B & 0b11111001; //no timer pre-scaler, fast PWM
