Lab 1 – Eeshema Schematic Editor
Step 1: Download Component and Footprint Library
- Create a new project and save it at the root of your drive. Example “C:/Kicad_First_Project”.
- Click the first icon to open Eeshema.
- Let’s build an example project based on Pinguino 18F4550.
- Download library from https://www.snapeda.com/parts/PIC18F4550-I/P/Microchip/view-part/ ,then unzip the downloaded library.
- Back to Eeshema. Go to “Preferences” and click “Component Libraries”.
- Click “Add”. Select “PIC18F4550-I_P.lib” at location you unzip the library, then click “OK“.
- Now you can use component pic18f4550 in your local library.
- Start pick your components by clicking “op-amp” like icon at your right-hand side panel.
- There are a lot components pre-installed in the local library. Use filter and type “18f4550” will get the result faster.
Step 2: Pick Other Components And Connect Them Together
- Pick other basic components like resistor, capacitor, LED, USB connector, and crystal.
- Start connecting them together according to Pinguino 18F4550 diagram.
Step 3: Annotate a Number To Each Components
- After completing circuit connection, press “annotate schematic components” button to help you assign component number.
- A window will pop up, click “Annotate” button then click “Yes“.
- Now you schematic is done and can proceed to draw PCB layout.
