    Hi everyone. Today i was testing the Micro-controller simulation in Proteus.
    I built a circuit and loaded the .hex file. When i try to simulate it i got an error.

    "CKSEL fuse bits specify external oscillator but no clock frequency is specified"

    I have used 12MHz crystal and selected external clock source but it isn't working. However, if i select internal clock option ,everything works fine.
    Please correct me.:confused:

    I am unable to attach the files to the thread. Please help me

    On ISIS open your DSN file. Use Edit>Copy to clipboard,

    Open microsoft "PAINT", paste your picture and save as .PNG file then you can post it here.

    You can also create a zip file of your project , and post the zip file. However not everybody do have Isis proteus installed. I prefer pdf files. And I use this free tool a lot http://www.pdfforge.org/pdfcreator
