DESCRIPTION

This program reads the fuse values from an AVR microcontroller using a UPDI interface, and prints the current values.

OPTIONS

--port, -P DEVICE

Optional. Provides the USB device where the UPDI adapter is connected. If absent a default of /dev/ttyUSB0 will apply.

--part, -p PART

Required. Gives the name of the ATmega or ATtiny chip that is expected. Parts may be specified in the following ways:

ATmega4809
atmega4809
m4809

ATtiny814
attiny814
t814

Specifically, these are the same forms as recognised by avr-gcc's -mmcu option and avrdude's -p option, for convenience in Makefiles and build scripts.
