Hello.
I recenty built my own version of smd pcb for nodle1 with small modifications. Now, I just have to program the atmega32u4. But I can't find any information about fuse bits. Can someone please tell me which fuses must be writen?
Thank you.

None because we use the internal bootloader!

Thank you for reply. I already finished the project. My atmega arrived empty and I had to upload a bootloader on it with a programmer.

Hi,
there's already a bootloader on the ATMega32U4 !
If you pull down Pin HWB and performing a Reset, the ATMega will start it's internal DFU-Bootlader.
Then you can Upload the .hex-File by Using Atmels FLIP!-Tool via USB. -

Hm, thats strange !
If the ATMega32U4 was a new one, there must be a DFU-Bootloader which you can program with Atmels Flip-Tool via USB.
This is so specified by Atmel and is also sold by Atmel.Maybe you got a "China"-One ?
Or you haven't installed the DFU-Drivers before you tried to program with FLIP. -
If you buy an Arduino Uno clone from China, the serial interface chips are not what you might expect. The serial interface is a CH340 UART and it requires a different driver than the one supplied with either the Arduino or ATMEL software.

rieka, we don't talk about Arduino ! We talk about the bare Microcontroller - these are directly shipped from Atmel with preloaded DFU-Bootloader. There's no Serial to USB Chip or similar.
