Timesaving Techniques & Block Editing
Armed with all of the basic techniques we can now look at the other blocks of circuitry on the
front sheet of the design, practice what we have covered so far and introduce a couple of new
timesaving techniques. Let’s start by drawing the dsPIC33 block as shown here:
dsPIC33 Circuit section
You should be able to tell which components go where by comparing the component names in
the Object Selector to the parts labels on the screenshot above. For clarity however, you can
use the following table as a reference:

Begin by placing and wiring the oscillator and power sections (left hand side) of this circuitry
using the methods outlined in the previous sections. When you are ready we’ll look at the right
hand side, where we can use a couple of additional features to speed up the process.
Proteus has a very useful feature to help with schematic wiring when we are laying out a series
of topologically identical wires. Essentially, it allows us to auto-repeat the last wire placed to
form a new connection.
