I know this has probably been very well said several times
but i wanted to be able to use 16 Mhz external Osciallator and according to the datasheet i think not only i will need to set CKSEL[3..0] to 1000 - 0101 but also i will need to enable CKOPT since i want to use over 8Mhz
I was just wondered if someone could help me understand this better.
I have been reading that it's possible to program fuses bits directly by using ISP just like you would normally bootload the chip. for example a cmd like "avrdude -c usbtiny -p m32" however i don't know which commands to send to the chip. in terms of setting up Low, High & Ext fuses so i can be able to use 16 Mhz.
and if i remember well somebody pointed out that i will need an extra clock signal aswell.
I am using Atmega32 , Winavr and ISP with Usbtiny as a programmer and avrdude to connect to MCU
Any help is very much appreciated
