The bus signal lines have a name, that must selected
with ![]()
For example, in TUTOR1.SCH you can try to remove, with
To check new wirings, use |
![]() | With ![]() |
You can place many signal ports with the same name, so they will
be electrically wired togheter. Always use to check the
real electrical circuit connections.
![]() | A signal line can be transported by a bus simply
placing an extemity of it over the bus. With ![]() ![]() |
![]() | There are another mode to link schematic circuit components to
pcb elements: using joint. These are schematic components
that the user can assigns at one specific pin of every pcb component.
These elements are very useful, for example in case of big pcb connector, that cannot
be drawn in a schematic file.
In fact, because pcb components have many different footprints, it's hard to draw for every pcb connector, its schematic equivalent shape. |
The joint is a schematic component, only maded by a single pad and, optionally, by some silk elements (the one I use is maded by a pad and a little external circle silk). To make a joint type component, for example in the COMP_SCH.LIB library file, follow the Lesson 5 steps to make a schematic component, using "Pattern" = JP, "Ref ID" = JP?-?. The other fields must be left blank.

In the image above you can see that the joints connected to the same pcb component have the same number, followed by the pcb component pin number. All the same group joints must be assigned to the same pcb component. To better understand how joints works, you can download the file PicProgr.zip (17 Kb .zip) that contains the PICPROG.SCH file, where I've token the example above.
