    Hello,

     

    I am attempting to follow the RFID to Atmega16 tutorial, I have everything set up, now I would like program the chip, in AVR studio4 . However, I am unsure how to set the ATMEGA16A to use an external 12MHz crystal. I understand I must change the fuse bits, but after reading the data sheet I’m still unsure what I need to do. I have heard you can brick your MC if this is done wrong any advise?

     

    Thanks

    if you are using SINAPROG to program AVR microcontrollers

     

    it very user friendly

     

    in its window it displays saparate buttons for programmig

     

    fuse bits
