AVR fuses

[Martin Hanek]

Mam v poznamkach priklad:

Nastaveni AVRDUDE (programovani):
---------------------------------
flash:
------
avrdude -p m8 -c sp12 -U flash:w:wiikey19.hex -U lfuse:w:0xE4:m -U 
hfuse:w:0xD8:m -U lock:w:0xCF:m

-p m8					ATMega8
-C sp12					Steve Bolt's Programmer
-U flash:w:wiikey19.hex			memory flash, write file wiikey19.hex
-U lfuse:w:0xE4:m			low fuse byte, 	write immediate mode: 11100100
-U hfuse:w:0xD8:m			high fuse byte, write immediate mode: 11011000
-U lock:w:0xCF:m			lock byte,	write immediate mode: 11001111

eeprom:
-------
avrdude -p m8 -c sp12 -U eeprom:w:PAL.eep

-p m8					ATMega8
-C sp12					Steve Bolt's Programmer
-U eeprom:w:PAL.eep			eeprom, write file PAL.eep


Napriklad toto je pro ATmega8. Pojistky jsou popsany na strane 222 a 
dale v datasheetu. Mejte na pameti ze 0 znamena naprogramovany bit a 1 
nenaprogramovany.

> Dobry den,
> zacinam zkouset programovat AVR-ka v C-ku. Jdu na to pod linuxem (Xubuntu 8.04). Jako prekladac pouzivam avr-gcc a programator pouzivam avrdude. Zkusil sem si napsat maly programek na blikani LEDky. Jenze sem narazil na problem s fuses. Do datasheetu koukam uz skoro dve hodky a sem z toho stale zmaten. Mohl by mi nekdo prosim poradit jak nastavit fuses.
