Rotate 45 degrees diptrace9/11/2023 ![]() ![]() In the case of this board, there are currently 7 warnings and no errors. This takes what Eagle knows about the various parts (which isn't very much), and checks to see if anything unusual is going on. One last way to see any idiosyncrasies that might be missed by the naked eye is the Electrical Rules Check (ERC). To do this, click the Display button, and un-check the Values layer (layer 96). To get the schematic to look cleaner, we can turn off the display of the values of all of the parts. If you click the show button, then click on the VCC net (a net is one of the green lines), you will see that all of the VCC nets get highlighted, including the one connected to that regulator, whose name couldn't be read clearly due to the name of the diode beneath it overlapping with the name of the VCC trace. If you are only running the freeware version, you can just close that section and never think of it again.Īfter you look at the schematic for a while, you may realize that this schematic could be laid out better (especially around the voltage regulator, highlighted above). With complex schematics (and non-freeware versions of Eagle), you can create multi-paged schematics and switch between them here. On the left, just right of all of the buttons, you can see a sheets area. ![]() F5 centers the screen where the mouse is.ģ) Drag the bars on the bottom and sides of the screen and zoom using the button of the top Middle-click and drag to move around, scroll up and down to zoom in and out There's three different ways to move around in Eagle (If you have a mouse, use 1, otherwise if you have a keyboard that has F# keys, use those, otherwise, if you're some poor soul who doesn't have either, you may be stuck using the scroll bars): The schematic window is where you create and edit the schematic (obviously). Hit F5 or go to View-Refresh in the Control Panel to make the files show up there.ĭouble-click on the Compass.sch file and the schematic and pcb file should both load. So to start things off, right-click on the 'eagle', select 'New Project', and call it ex-Compass.ĭownload the 'Compass.sch' and 'Compass.pcb' files from below, and save them in the Documents\eagle\ex-Compass pcb, etc) are where your circuit boards, schematics, and whatever else live CAM Jobs (.cam) export to other formats Scripts (.scr) are essentially just groups of eagle commands commands. User Language Programs (.ulp) use Eagle's User Language (pretty much an advanced scripting language) to do stuff that would normally be difficult, tedious, or impossible without them. Design Rules (.dru) are what the design rule checker (aka the idiot-checker) uses. Libraries (.lbr files) store the individual parts that you add to your board. When you close it, all windows that it opened get closed as well.Ī description of the various categories in the Control Panel: The control panel is the main window of Eagle. On Schematics, parts are laid out where they make sense electrically, on Boards, they are laid out where they physically make sense, thus a resistor that is right next to a part in the Schematic may end up as far away from that part as possible in the Board. Only in Board layout does it matter where the parts physically go. Note that the Schematic's job is only to define the parts and the connections between them. It defines the parts you have in your project, and which pins on the parts should be connected.īoard - This is where you lay out the pieces of your project and physically connect the correct pins as defined in the Schematic. Schematic - This is where you draw the schematic for your project. Advanced usage of this will not be covered in this tutorial Library - Allows you to manage and edit parts. When used properly, this allows you to work very rapidly, but it can also be a major source of aggravation if you are used to the Windows-y way of doing things.Įagle has four basic views: Library, Schematic, Board, and Control Panel.Ĭontrol Panel is the main window, it launches everything else and when you close it, all subordinate windows get closed. That is, you select one mode, perform it a bunch of times, as opposed to selecting an object and applying an single operation at a time. Eagle's UI is designed with what is called a modal interface.
