Under Windows run kicad.exe. Under Linux type 'kicad' in yourTerminal. You are now in the main window of the KiCad projectmanager. From here you have access to eight stand-alone softwaretools: Eeschema, Schematic Library Editor, Pcbnew,PCB Footprint Editor, GerbView, Bitmap2Component,PCB Calculator and Pl Editor. Refer to the work-flow chartto give you an idea how the main tools are used.
Select the Project Specific table.Click the file browser button below the table.You need to find where the official KiCad libraries are installed on yourcomputer. Look for a library directory containing a hundred of .dcm and.lib files. Try in C:\Program Files (x86)\KiCad\share\ (Windows) and/usr/share/kicad/library/ (Linux). When you have found the directory,choose and add the 'MCU_Microchip_PIC12.lib' library and close the window.It will be added to the end of of the list.Now click its nickname and change it to 'microchip_pic12mcu'.Close the Symbol Libraries window with OK.
Repeat the add-pin steps but this time select the GND part. Place aGND part under the GND pin of 'MYCONN3'. Place another GND symbol on theleft of the VSS pin of the microcontroller. Your schematic should nowlook something like this:
From the KiCad project manager, click on the 'Pcb layout editor' icon. You can also use thecorresponding toolbar button from Eeschema.The 'Pcbnew' window willopen. If you get a message saying that a *.kicad_pcb filedoes not exist and asks if you want to create it, just click Yes.
Unlike other EDA software tools, which have one type of library thatcontains both the schematic symbol and the footprint variations, KiCad.lib files contain schematic symbols and .kicad_mod files containfootprints. Cvpcb is used to map footprints to symbols.
When you have a KiCad project to share with somebody, it is importantthat the schematic file .sch, the board file .kicad_pcb, theproject file .pro and the netlist file .net, are sent togetherwith both the schematic parts file .lib and the footprints file.kicad_mod. Only this way will people have total freedom to modify theschematic and the board.
With KiCad schematics, people need the .lib files that contain thesymbols. Those library files need to be loaded in the Eeschemapreferences. On the other hand, with boards (.kicad_pcb files),footprints can be stored inside the .kicad_pcb file. Youcan send someone a .kicad_pcb file and nothing else, and they wouldstill be able to look at and edit the board. However, when they wantto load components from a netlist, the footprint libraries (.kicad_modfiles) need to be present and loaded in the Pcbnew preferences justas for schematics. Also, it is necessary to load the .kicad_mod files inthe preferences of Pcbnew in order for those footprints to show up inCvpcb.
Bottom line, if the PCB is the only thing you want to distribute, thenthe board file .kicad_pcb is enough. However, if you want to givepeople the full ability to use and modify your schematic, itscomponents and the PCB, it is highly recommended that you zip and sendthe following project directory:
The biggest advantage Altium Designer offers over KiCAD is the ability to access all the essential PCB design features in a single program. Industry-standard capabilities like CAM tools, a layer stack editor with integrated field solver, high speed analysis features, and many powerful extensions are included in Altium Designers. Large teams and experienced professionals trust the powerful interface and complete set of design tools in Altium Designer for their projects:
I have schematics created within KiCad, and I would like to bring those into TI-PSPICE for simulation. Many (most) of the elements defined by the KiCad Netlist would ___ be imported with pre-assigned simulation models.
The (unfortunate) best solution in KiCAD as of May, 2017 is to edit the footprint, place the cutout in the 1_________ (engineering change order, which I like for this -- some people prefer 2_________), save the footprint and the open the footprint library in a text editor. Once in the text editor, scroll down until you find the footprint and then COPY the cutout section from 3_________, paste and set the pasted layer to 4_________.
Fritzing works seamlessly in all modes, Schematic to PCB, whereas Kicad does require a netlist export. So kicad is more of a multiple program all based-in-one solution.Those programs are; Eeshcema, pcbnew, GerbView, a schematic library editor, and a PCB footprint editor.
KiCad is a free and open-source Printed Circuit Board (PCB) design tool. PCBs are the electronic cards you see when you open your PC, satellite receiver or TV set. These printed circuit boards are designed with a tool like KiCad and then fed into the production lines.
The next steps were to annotate the symbols and assign footprints to them. I did this by clicking the button with a R?? -> R42 that was to the left of the electrical rules check symbol in the top toolbar that looked like this. Once I clicked it, it brought up a popup which gave me the option to annotate. I clicked that, and the popup said something like this
This is what it would look like without a resistor. In concept, a pullup and pulldown resistor are the exact same things, just on opposite sides. A pullup resistor means that the normal analog value is 5V, and a button press would bring the digital value down to 0. An example of this would be if you started a program, and the LED was always on, but when you pressed the button, the LED turned off. This is what a pull up resistor would look like, and as you can see, the resistor is on the power side.
A pull down resistor is essentially the same thing but reversed. Instead, it pulls the normal analog value to 0, and a button press would produce a 1 digital value. For instance, if a button was pressed the LED would turn on, but it would otherwise remain off. This is what a pull down resistor would look like, and as you can see, the resistor is on the ground side.
Now the final steps for the schematic were to add in the wiring and perform an Electrical Rules Check. I first focused on the ATTiny412 and I noticed that it had 8 pins. However I thought I only needed 4 of them - 1 power, 1 ground, a data line for the button, and a data line for the LED/Resistor. At first, I wired the schematic up like this, using the PA6 and PA7 pins of the chip.
This is what the milled board looked like. Overall, the traces were very nicely milled but the only thing I would change for the next time would be the trace width and trace clearance as these made solder bridges very common when soldering.
For soldering the board, I used the method of soldering one pad, securing the component with tweezers then soldering the other pad. Unlike week 05, I did not have as many issues with soldering because this board was simpler and I am better with soldering now. I referred to my PCB layout in KiCAD, and it was very easy to figure out which component went where.
Then I realized my mistake, which was that I was using the wrong pins. Instead of using pins 4 and 5, I should have been using pins 2 and 3 instead. When I switched the code, this is what the code looked like. 5376163bf9
