Si consiglia la prima opzione (Copia tabella libreria simboli globale predefinita (consigliato)). La tabella librerie impronte predefinita include molte delle librerie impronte standard che sono installate assieme a KiCad.
Se questa opzione disabilitata, KiCad non stato in grado di trovare la tabella della libreria di simboli globale predefinita. Questo probabilmente significa che non sono state installate le librerie di simboli standard con KiCad, o che non sono installate dove KiCad si aspetta di trovarle. Su alcuni sistemi le librerie KiCad sono installate come pacchetto separato.
Se si ha installato le librerie di simboli standard di KiCad e vuole usarle, ma la prima opzione disabilitata, selezionare la seconda opzione e andare al file sym-lib-table nella cartella in cui sono state installate le librerie di KiCad.
By default, dragging with the middle or right mouse button will pan the canvas view and scrolling the mouse wheel will zoom the view in or out. You can change this behavior in the Mouse and Touchpad section of the preferences (see Configuration and Customization for details).
Selecting items in the editing canvas is done with the left mouse button. Single-clicking on an object will select it. Clicking and dragging will perform a box selection. A box selection from left to right will only select items that are fully inside the box. A box selection from right to left will select any items that touch the box. A left-to-right selection box is drawn in yellow, with a cursor that indicates exclusive selection, and a right-to-left selection box is drawn in blue with a cursor that indicates inclusive selection.
Uno schema elettrico consiste principalmente di simboli, fili, etichette, giunzioni, bus e simboli di potenza. Per chiarezza, negli schemi elettrici, possibile inserire elementi puramente grafici come elementi bus, commenti, e polilinee.
Schematic editing tools are located in the right toolbar. When a tool is activated, it stays active until a different tool is selected or the tool is canceled with the Esc key. The selection tool is always activated when any other tool is canceled.
Schematic elements such as symbols, wires, text, and graphic lines are snapped to the grid when moving, dragging, and drawing them. Additionally, the wire tool snaps to pins even when grid snapping is disabled. Both grid and pin snapping can be disabled while moving the mouse by using the modifier keys in the table below.
All objects have properties that are editable in a dialog. Use the hotkey E or select Properties from the right-click context menu to edit the properties of selected item(s). You can only open the properties dialog if all the items you have selected are of the same type. To edit the properties of different types of items at one time, see the section below on bulk editing tools.
In properties dialogs, any field that contains a numeric value can also accept a basic math expression that results in a numeric value. For example, a dimension may be entered as 2 * 2mm, resulting in a value of 4mm. Basic arithmetic operators as well as parentheses for defining order of operations are supported.
Per piazzare un simbolo nello schema elettrico si pu usare il pulsante o il tasto A. Appare la finestra di dialogo Scegli simboli che consente di scegliere il simbolo da aggiungere. I simboli sono raggruppati per libreria.
Dopo aver selezionato un simbolo da posizionare, il simbolo verr attaccato al cursore. Facendo clic con il pulsante sinistro del mouse sulla posizione desiderata nello schema, il simbolo viene inserito nello schema. Prima di posizionare il simbolo nello schema elettrico, possibile ruotarlo, renderlo speculare e modificarne i campi, usando i tasti comando o il menu contestuale del tasto destro. Queste azioni possono essere eseguite anche dopo il posizionamento.
I simboli possono essere spostati utilizzando gli strumenti Sposta (M) o Trascina (G). Questi strumenti agiscono sul simbolo selezionato, oppure se nessun simbolo fosse stato selezionato, agiscono sul simbolo sotto il cursore.
Il nome e il valore di ciascun campo possono essere visibili o nascosti e sono disponibili diverse opzioni di formattazione: allineamento orizzontale e verticale, orientamento, posizione, carattere, colore del testo, dimensione del testo ed enfasi in grassetto/corsivo. Il posizionamento automatico del campo pu anche essere abilitato in base al campo. La posizione visualizzata sempre indicata per un simbolo visualizzato normalmente (nessuna rotazione o specularit) ed relativa al punto di ancoraggio del simbolo.
Do not populate means that the component should not be attached to the PCB,although a corresponding footprint should still be added to the board. DNPsymbols appear desaturated and with a red "X" over them in the schematic, asshown below.
When a symbol is added to the schematic, KiCad embeds a copy of the library symbol in the schematic so that the schematic is independent of the system libraries. Symbols that have been added to the schematic are not automatically updated when the library changes. Library symbol changes are manually synced to the schematic so that the schematic does not change unexpectedly.
The top of the dialog has options to choose which symbols will be updated. You can update all symbols in the dialog, update only the selected symbols, or update only the symbols that match a specific reference designator, value, or library identifier. The reference designator and value fields support wildcards: * matches any number of any characters, including none, and ? matches any single character.
The middle of the dialog has options to control what parts of the symbol will be updated. You can select specific fields to update or not update, which properties of the fields to update (text, visibility, size and style, and position), and how to handle fields that are missing or empty in the library symbol. You can also choose whether to update symbol attributes, such as do not populate and exclude from simulation / bill of materials / board.
The Map Orphans button attempts to automatically remap orphaned symbols to symbols with the same name in an active library. For example, if there is a symbol with the current library reference mylib:symbol123, but the mylib library cannot be found, the Map Orphans button will attempt to find a symbol named symbol123 in any of the libraries that are present. This button is only enabled if orphaned symbols are present in the schematic (see the legacy schematics section).
This dialog is primarily useful for managing symbols that appear in multiple libraries, when you want to switch from one library to another. For example, if a schematic uses symbols that are in both a global library and a project-specific library, the Symbol Library References dialog could be used to switch between using the global symbols or the equivalent project-specific symbols. It does not have features for fine-grained control of how fields are updated; for that, use the Change Symbols dialog.
A range of cells can be selected by clicking and dragging. The whole range of selected cells will be copied (Ctrl+C) or pasted into (Ctrl+V) on a copy or paste action. Copying a range of cells from the table can be useful for creating a BOM. More details of copying and pasting cells are described below.
Similar symbols can optionally be grouped by any symbol field using the Group By checkboxes. Grouped symbols are shown in a single row in the table. The grouped row can be expanded to show the individual symbols by clicking the arrow at the left of the row. The Group Symbols checkbox enables or disables symbol grouping, and the button recalculates groupings.
Symbols can be filtered using the Filter textbox at the top. The filter supports wildcards: * matches any number of any characters, including none, and ? matches any single character.
Esistono diversi metodi speciali di copia/incolla nel foglio di calcolo per incollare i valori in regioni pi grandi, comprese le celle incollate con incremento automatico. Queste funzionalit possono essere utili quando si incollano valori condivisi in pi simboli.
Reference designators are unique identifiers for components in a design. They are often printed on a PCB and in assembly diagrams, and allow you to match symbols in a schematic to the corresponding components on a board.
Scope: Selects whether annotation is applied to the entire schematic, to onlythe current sheet, or to only the selected symbols. If theRecurse into subsheets option is selected, symbols in subsheets of theselected scope will be reannotated; otherwise symbols in subsheets will not bereannotated. For example, if Recurse into subsheets and Selection onlyselected, symbols in any selected subsheets will be reannotated.
Order: Chooses the direction of numbering. If symbols are sorted by Xposition, all symbols on the left side of a schematic sheet will be lowernumbered than symbols on the right side of the sheet. If symbols are sorted by Yposition, all symbols on the top of a sheet will be lower numbered than symbolsat the bottom of the sheet.
There are two primary ways to establish connections: wires and labels. Wires make direct connections, while labels connect to other labels with the same name. Both wires and labels are shown in the schematic below.
