Interfacing PIC Microcontrollers

automatically saved and re-assembled at this command, which provides one-

click retesting. This saves a lot of time during the development process, espe-

cially for the inexperienced programmer.

The circuit will operate in real time if the animation settings are correct, and

the simulation is not too complex. The default animation settings (System, Set

Animation Options) are 20 frames per second and 50 ms per frame, giving

real-time operation (20⫻50 ms = 1 s). For other applications and clock

speeds, these settings may need to be modified to see the circuit operation

clearly. In this circuit, the output LEDs should show a visible binary count; as
