    Thank you somuch, I’m new on avr.
    I saw in data sheet of atmega328p section 31. MEMPROG- Memory Programming, fuse byte tables show default value:
    High byte = 0xD9
    Low byte = 0x62 , CKDIV8 is programmed and CKSEL[3:0] = 0b0010 (Calibrated Internal RC Ocillator)

    does changing fuse bits causes any problem?? and is it irreversible??
    i have given my high fuse bit =c9
    low fuse bit =ff..
    and im getting rc=-1 error even after changing fuse bits to its default value its not working..

    to connect an external crystal oscillator of 16 Mhz to atmega 16 ,the only thing which i require to adjust is fusebit settings in the extreme burner software while programming atmega 16 or something more…….?

      Nothing else is required. But make sure that, you do the fuse-bit settings correctly. You have to do that first and then burn the code.

    Thanks a lot man 😀 This is just what I was looking for….. 🙂
    I noticed my usbasp just wouldnt read the atmega16 clocked by the internal 1MHz clock… Setting the isp clock delay to 3 solved the problem 🙂
    avrdude -c usbasp -p m16 -i 3

    Thanks
