Hi everyone. Today i was testing the Micro-controller simulation in Proteus.
I built a circuit as shown below 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.
