Good morning at all.
I want built this:
http://www.cithraidt.de/joyadapter/index.html
I need to change the fusebits of the atmega8.
1) first i flash with hex files and only AFTER i change the fusebits?
2) When i have changed the fusebits (ext. rc. osc. to 12 mhz) , i can not do it anymore (reprogrammed)?
3) the setting with ponyprog is EXT. rc. osc. 8.0 mhz -12.0 mhz startup time 6 CK + 4ms (cksel =1000 SUT=11) :
spien
ckopt
cksel 0
cksel 1
cksel 2
It's correct?
Is it necessary to change sut too? In what way?
