There are some references and appendix information at the end of this document that can help if further assistance is needed with the techniques not focused on in this paper. Throughout this paper there is the assumption that the components layout have already been created and that the user is familiar with the procedure. The four steps needed are Component design, Pattern Library design, Schematics Layout and the PCB layout. These are two of the four steps needed to create a PCB design using this software. This document will walk the user through creating and using pattern libraries and schematics layouts in DipTrace.
#Diptrace Arduino Libraries software
Keywords DipTrace, Pattern Libraries, Schematic Layout, PCB Design, PCB Introduction DipTrace is a software application for creating schematics and printed circuit boards (PCB) 1. These are two key steps needed in the design of the PCB that will hold the PSOC First Touch Kit and the Arduino Ethernet Shield.Īt the end of the design the user will be ready to layout the PCB for fabrication. To name each header component use the Pattern Property window displayed in the upper right hand side corner of the screen. These executables are provided pre-compiled for all platforms OS officially supported by Yoctopuce.
Those files are quite big because they include a lot of pre-compiled examples with source files. Some languages, such as Javascript and PHP, also require the Virtual Hub software. There is one library per language, which can control all available modules. 8.In the MegaPi firmware, SLOT1 is changed to slotnum instead of parameter transmission in the command processing stepper motor. You can get my “production version” PCB file, which has a grid fill for the pour, as well as some other tweaks to pass Olimex fab requirements.CPP file). I chose a solid fill and to remove unconnected islands of copper. The final video shows how I add a copper pour on the bottom layer. Towards the end, I also make one more tweak so the crystal caps have square pads for positive terminals (it just looks slightly better even though ceramic capacitors are not polarized :) If you look carefully through the video, you’ll notice that I still had the crystal capacitors turned the wrong way, and at 3:06 the software asks if I really want to merge two nets that were previously unconnected. Note that “T” and “B” keys toggle between top and bottom signal layer!Īs you can see, I configured the trace options so that VCC trace is a bit thicker – GND is a smaller issue, as I’m using ground copper pour which should fix that later on. I Before routing, I tweak the component locations a bit, and make the header holes and pads slightly larger (square header pins require slightly larger holes than normal through-hole components). After some head-scratching, I managed to figure out a way to avoid vias completely, and this is what I use here. DipTrace has an autoroute option, but it doesn’t do as good job as a human would – I tried it and while it worked OK, it had to make one or two vias (metal-filled holes that go through the PCB to enable a trace to go from one side to another outside the component mounting holes). The most important and many times the hardest part of the PCB design is routing. DipTrace also has an excellent “Replace pattern” option that lets me change the pattern used for a given component, which I used to replace crystal capacitor patterns with one that takes up less space on silk screen (the distance between pads stays the same, though). Sorry for that! However, I trust you’ll be able to find the correct option yourself if you look at the window that then pops up – usually it’s “xxx properties”, like component or pad properties that I open.Īfter getting the components more or less to their correct locations, I then draw a board outline (after adjusting the grid to a slightly fines 2.5 mil pitch). You probably notice that at some points of the video, the popup-menu options go outside the recording area. Spacebar is again used to rotate components 90 degrees, and multiple items can be selected with ctrl+click.
I then remove some component names which are not sorely needed, and change the location for the remaining ones to the center of the component. I then proceed arrange the components roughly to final layout, and add two 10-pin headers which will plug into breadboard. Like it’s schematic counterpart, also this tool is quite easy to use.įirst I change the grid to 5 mil so each step is half of the 10 mil breadboard hole spacing. In DipTrace Schematic Editor, I used File->Convert to PCB (CTRL-B) to get the components and connections exported to PCB Layout tool.
Continuing from part 1 of this ATtiny2313 breadboard header with DipTrace -tutorial, I’ll now go through the PCB design.
