我的avrdude烧写总是出现这个问题
我在ubuntu12.04下面用avrdude烧写avr程序，总是出现一个问题。但是有的时候就不出现，然后烧写成功。sudo avrdude -c usbasp -F -pm16 -e -U flash:w:LED2.hex:i
avrdude: warning: cannot set sck period. please check for usbasp firmware update.

Would you like this fuse to be changed back? n

avrdude: safemode: Fuses OK
avrdude done.Thank you.
高手帮帮忙啊，这到底是怎么回事啊，郁闷了好几天了。 更换usbasp下载器的排线，
它自身的排线芯线比较细，传导不良，
换成粗些的排线。
以上是我“下多一次晕多一次”之后的发现，从此再无烦恼。
