The beginning step is to add a Schematic Document. This is where the schematic drawings we are all familiar with will go. Right click and save the schematic document as before. Organization  Your screen should now look like this. Notice the branching. The PIC schematic document is located in the project tutorial. Libraries  There are three forms of libraries  Schematic Library- This library contains schematic drawings that we are familiar with from ORCAD  PCB/Footprint Library- This library contains the actual dimensions and pads for placing the component on the board.  Integrated Library- Most manufacturers libraries are integrated, containing both Schematic and PCB libraries. Adding Libraries  From the design menu, click Add/Remove libraries. [...]... you highlight a part, Protel shows both the schematic layout (top right) and the PCB layout (bottom right) Schematic Layout- Placing Parts PIC18F452-E/P : 40 pin DIP package, DIP’s are very good for beginners due to their large size and easy solderability Schematic Layout- Placing Parts Which to choose? That’s up to you! But for this tutorial, lets use a DIP package Schematic Layout- Placing Parts... Pins Schematic Layout- Placing Parts Don’t worry if you don’t know what terms like PLCC, QFN, TQFP, DIP mean at the moment You can look at the Protel layout and it will show you what the footprint differences are Schematic Layout- Placing Parts PIC18F452-E/L : This is a PLCC-44 package In the bottom left corner you can see the description of the package including dimensions Schematic Layout- Placing... the Library folder, go to the PCB folder, this folder contains PCB footprint libraries Adding Libraries (Cont.) From the PCB folder, add Chip Capacitor Chip Resistor Crystal Oscillator Resistor- Axial Adding Libraries (Cont.) You should now have the following libraries installed Note the top three libraries here are integrated libraries, and the bottom four libraries are PCB libraries Checkpoint If... see the following Now that we have added our libraries, we are ready to begin the schematic layout Schematic Layout Double Click on your schematic document from the left navigator menu, and you should see a blank screen on the right Schematic Layout- Placing Parts From the ‘Place’ menu, click Part Schematic Layout- Placing Parts The ‘Place Part’ screen will appear Click the box in the top right with... bottom right, it will show you the PCB footprint for this part Schematic Layout- Placing Parts We need power for our circuit, but unlike pspice, we must add a physical way to add power to our device Add ‘HEADER 2’ from the Miscellaneous Connectors library As seen from the PCB footprint below, this is just two holes in the board where we can connect wires Schematic Layout- Placing Parts Our updated... ‘place part’ popup menu This allows you to verify the part you chose Schematic Layout- Placing Parts Your PIC should now be placed in the schematic document A very important note is that you need to give this an identifier If you leave this as ‘U?’ you will get an error So double click and change the identifier to U1 Schematic Layout- Placing Parts Double click on the PIC, you will get a Component Properties... the ‘Browse Libraries’, which is just a list of a few default libraries and all the libraries we have added to the project Schematic Layout- Placing Parts From the ‘Libraries’ drop down box, look for the Microchip Microcontroller library we added earlier Schematic Layout- Placing Parts Choosing the PIC18F452 for our project we see there are three choices in the list Which one do we choose? Why is... the menu bar up top Schematic Layout- Placing Parts Be EXTREMELY CAREFUL when connecting wires The end of the wire must be on the end of the part, when this happens you will get a red ‘X’, Do not rush through this step, and always verify there is a proper connect WRONG!!!!!! Gray ‘X’ This will not connect the part Correct Red ‘X’ This WILL connect the part Schematic Layout- Adding Nets On simple projects,... slide) Click the ‘NET’ icon in the toolbar and place this text on both lines, labeling them both GND This is the same exact thing as actually running wires between them Protel knows that these two pins should be connected Schematic Layout- Adding Nets You should now have the following Notice the blue dots on pin 12 and pin 11, the dots appear when more there is a connect of more than 2 areas In the .
