the crystal oscillator seems not working in Proteus, there is no signal out from the crystal oscillator component. i placed a voltage probe at all the pins around it.
Yes, Crystal in Proteus doesn't work and also for microcontroller projects you don't have to use crystal model in Proteus instead double click the MCU in Proteus and for Processor Clock Frequency enter somethink like 4MHz or 20MHz or the value you require and OK it.
