Topic: Can fuses be burnt using Arduino IDE? (Read 390 times) previous topic - next topic

I am using Atmega328. I need to switch from internal oscillator to 8Mhz crystal, so the fuses need to be changed. Is it possible to change the fuse value using Arduino IDE? Or is it necessary to buy a AVRISP programmer to change the fuse value?

Thank you.

You can do it using another Arduino as an AVRISP programmer.

Yes, but not with a USB connection.

Yes.
No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Yes.



You can do it with another Arduino, you dont have to buy a programmer.

for example:

avrdude -p atmega328P -c avrisp -P com3 -b 19200 -u -U efuse:w:0x05:m -U hfuse:w:0xDA:m -U lfuse:w:0xFF:m -U lock:w:0x0F:m
