The LST source for this example is already compiled and is available as Lesson1.LST.
To select it as the source code for the PIC16C54 click on the Filename property in the property editor. The Filename property will become active and show the FileOpen button.
Click the FileOpen button to launch the FileOpen Dialog. Use the FileOpen dialog to locate the Lesson1.lst file and select open.
The filename should now appear in the properties editor (although the name may sometimes be too long to be completely displayed within the text box).
After placing the PIC somewhere between the TIMER and LED8, your screen should
look something like this.
So now we are well down the track for building this application. All that remains is to link the components together and run the application. However what we really want to do is to tidy up the locations of the components so make the circuit nice and neat. A neat circuit is always easier to understand.
Virtual Breadboard has a permanent grid and all components are designed to align to this grid which makes it easy to align components and build neat circuits.
In this application PORTB of the PIC is going to be linked to the pins of the LED8 display. At this point however the pins are facing the same way and a link between them is required to travel an unnecessary distance.
What we really want is to turn the LED8 component around and buff it up against the PIC PortB so the links are short and unnoticeable.
To turn the LED8 component around we need to first select it and then click one of the component rotation tools twice.
