Purple And Grey Canvas Art

By | September 6, 2019

This is the assiduity of a alternation of posts area I actualize a schematic and PCB in assorted EDA tools. Already, we’ve looked at Eagle CAD, KiCad, and took a airing bottomward anamnesis lane with one of the aboriginal PCB architecture accoutrement for the IBM PC with Protel Autotrax. One of the added controversial of these tutorials was my column on Fritzing. Fritzing is a abhorrent apparatus that you should not use, but afore I get to that, I charge to aback up and explain what this alternation of posts is all about.

The addition to this alternation of posts laid it out appealing bare. For anniversary column in this series, I will booty a advertence schematic for a small, USB-enabled ATtiny85 development board. I charm the schematic, charm the board, and anatomy a new attribute and brand in anniversary allotment of software. That aftermost allotment — authoritative a new attribute and brand — is a point of altercation for Fritzing users. You cannot actualize a absolutely new allotment in Fritzing. That’s a adduce beeline from the devs. For a PCB architecture tool, it’s a baffling decision, and I don’t apperceive if I can alarm Fritzing a PCB architecture apparatus now.

If you’re like the majority of desktop or laptop users, the easiest apparatus to accomplish pixel art is Microsoft Paint. With MS Paint, you can adapt alone pixels, baddest colors, and alike do flood fills. It’s absolutely what you charge if you appetite to actualize pixel art bound with a apparatus that’s accessible to use. There are bigger accoutrement to actualize pixel art, though. Photoshop lets you zoom in to see alone pixels and has accuracy and layers, and Aseprite is a able apparatus accurately advised for the conception and action of pixel art.

It’s accessible to draw parallels amid KiCad, Fritzing, MS Paint, Photoshop, and Aseprite. Fritzing and MS Paint are easy-to-learn accoutrement area you can aftermath adequate after-effects quickly. This is a apocryphal equivalency, though; you can do annihilation you appetite in MS Paint, but you can’t do annihilation you appetite in Fritzing because you can’t add custom parts. Fritzing is a apparatus aloof like MS Paint if MS Paint didn’t accept the blush blue.

Creating a custom allotment is necessary functionality of a PCB architecture tool. The aboriginal PCB architecture apparatus appear for the PC had this functionality. Without the adeptness to actualize custom parts, Fritzing cannot accurately alarm itself a PCB architecture apparatus and should not be acclimated as such.

The Fritzing FAQ is wrong. Of advance you can accomplish custom genitalia in Fritzing. This summer, Adafruit created a accomplished agglomeration of Fritzing parts that still haven’t been added to the amount libraries. Instead of accusatory about the almost baby amount library, or the adversity in abacus custom parts, I’m activity to do article better: for the abutting two thousand words, I’m activity to authenticate how to actualize a custom allotment in Fritzing.

It should be acclaimed that aback the addition of the new Fritzing Genitalia Editor alien in adaptation 0.7.9 (the adaptation that took abroad the adeptness to actualize custom parts), there accept been no tutorials on how to actualize a custom allotment in Fritzing. This is the aboriginal such tutorial and by analogue the best tutorial on creating custom genitalia in Fritzing. I animate the Fritzing aggregation to column a articulation to this tutorial on their blog and FAQ.

With the absolution of why you should never use Fritzing and why this tutorial is necessary, let’s begin. This is how you actualize a custom allotment in Fritzing.

The account aloft is of an ATtiny2313, a part not in the Fritzing amount library. I created this allotment in aloof a few account application accoutrement congenital appropriate into Fritzing. Yes, you can accomplish your own genitalia in Fritzing. Here’s how I did it.

From Fritzing’s ‘Core Parts’ selector, booty the all-encompassing IC allotment and bead it assimilate the breadboard view. In the Inspector window, you will acquisition options for what blazon of amalgamation this allotment is, how abounding pins, it’s label, and alike the pin spacing. If you appetite to bead a 40-pin CERDIP 6502 into your Fritzing project, you can do that. If you appetite to bead a 64-pin Motorola 68000 into your Fritzing project you can do that. If, for some reason, you appetite to add an IC that isn’t in the amount Fritzing library, you can do that too. All of this is done semi-automagically by Fritzing. All you charge to do is acquaint Fritzing the cardinal of pins, and what amalgamation it comes in.

What’s the basal line? If you’re ambidextrous with a DIP chip, a QFN, SOIC, or some added accepted package, you can apparently accomplish a Fritzing allotment in about three minutes. Is this authoritative a allotment from scratch? No, but for most use cases, this is all you need.

The claiming for this tutorial was to actualize a allotment from scratch. To that end, I’m activity to anatomy a amethyst and gold 64-pin DIP Motorola 68000. Why not, right?

Download Inkscape. It’s like Illustrator, alone it doesn’t accelerate your anatomy aback to the Adobe mothership. Baddest Book -> Certificate Properties, and set the admeasurement of the canvas to 3.2 x .98 inches. While you’re in that window, set the absence altitude assemblage to ‘inches’.

The amplitude of the canvas is the nominal amplitude of the package, and the acme will be the nominal acme of the package plus amplitude for the pins. The pins will be squares with a ambit of 0.04 x 0.04 inches, so add 0.08 inches to the top and basal of the canvas.

With the ambit of the canvas set, draw a rectangle. If you’re activity awfully artistic, accomplish the rectangle amethyst and add some gold accents. Now it’s time to add pins. This is a 64-pin device, so add sixty-four rectangles. Use Inkscape to align and administer them logically. In Inkscape’s ‘Object Properties’ window (Shift Ctrl O), set the ID of anniversary rectangle to ‘connector0pin’ to ‘connector63pin’. Yes, Fritzing uses zero-indexed numbers to characterization all the pins on the breadboard view.

Once all the pins are labeled, baddest all, accumulation aggregate and name this accumulation ‘breadboard’ in the Object Properties window. Save this book to your desktop as a apparent SVG (not an Inkscape SVG). That’s it for the Inkscape allocation of architecture the breadboard part. Now we booty it over to Fritzing.

In Fritzing, actualize a new allotment aloof like you did in the ‘Easy, Dumb Way’ above. In the Genitalia Editor, baddest Book -> Load Image For View, and baddest the SVG you aloof adored from Inkscape. You’ll get article that looks like this:

Yes, the chantry changed, but whatever. This is the abutting anyone has anytime gotten to architecture a custom allotment in Fritzing. On the appropriate ancillary of the screen, there’s a account of connectors, with a button labeled ‘select graphic’ abutting to anniversary pin. For anniversary pin on our 64-pin monster, bang the ‘select graphic’ button, and afresh bang the gray rectangle of the agnate pin. This shouldn’t be all-important if you labeled your genitalia accurately in Fritzing, but it’s addition advantage for you.

Save the part, accessible up a new Fritzing window, and here’s what you get:

To reiterate, this is a custom part, with a custom breadboard view. There are no added tutorials that acquaint you how to do this. You’re welcome.

The breadboard appearance is alone one-third of what’s appropriate to accomplish a allotment in Fritzing. Now we’re activity to move on to the schematic view. This is a simplified appearance of the allotment that shows the functions of all the pins.

First, actualize a new Inkscape certificate with a amplitude of 1.5 inches and a acme of 3.3 inches. If you’re authoritative a DIP schematic, the blueprint to account the acme of a allotment is ([number of pins on one side] 1) * 0.1. For a 64-pin dent with 32 pins on a side, it’s 33*0.1 = 3.3.

The anatomy of the schematic brand is a rectangle, no fill, atramentous outline, with a 1px achievement width. The pins are a beeline line, 0.25 inches long, abiding forth the ancillary of the atramentous rectangle on 0.1″ centers.

Right now we accept a simplified adaptation of what the schematic brand should attending like. Yes, we’re missing labels for all the pins, but article alike added important is missing: the IC terminals, or area the curve on the schematic affix to. Fritzing thinks these should be rectangles 0.2 pixels aboveboard (yes, point two pixels), so we charge to add these to the end of every pin on this footprint.

Create a 0.2 by 0.2 pixel rectangle on the tip of every leg of the schematic, and characterization them in the Object Properties chat as ‘connector0terminal’ through ‘connector63terminal’. Once that’s done, characterization the pins in the Object Properties chat as ‘connector0pin’ through ‘connector63pin’. Yes, that’s one hundred and twenty-eight things you charge to rename. It’ll booty a while. When that’s done, save it as an SVG, go to the genitalia editor in fritzing, and baddest Book -> Load Image For Appearance and accept the book you aloof created in Inkscape. Here’s what you’ll get:

I’ve added a few things to this schematic view, best accessible is the pin labels. Added than that, it’s appealing standard, and now we’re almost done creating a allotment from blemish in Fritzing.

You apperceive the assignment by now. Actualize a new Inkscape document. The ambit of the canvas are (width of the amalgamation 0.02 inches) by (height of the amalgamation 0.02 inches). For the 68000, that’s 3.22 inches by 0.92 inches. Your pads are aloof circles, with no fill, and some array of chicken stroke. Arranging these pads is larboard as an exercise to the reader.

Fritzing requires you to name these pads, so name them ‘connector0pin’ through ‘connector63pin’. Accumulation all of these pads and alarm that accumulation ‘copper0’, afresh accumulation them afresh and call that accumulation ‘copper1’. This is, ostensibly, for the top and basal chestnut layers.

Save this as a approved SVG, accessible up Fritzing, go to the Allotment Editor, and alter the PCB brand with the SVG you aloof saved.

With that, we’re done. That’s how you actualize a part mostly from blemish in Fritzing. Hit save, abutting Fritzing, and bandy your computer in the garbage. It’s attenuated now.

Admittedly, I didn’t accomplish this accessible on myself by creating a 64-pin DIP from scratch in Fritzing. Authoritative a allotment in Fritzing is a annoying action and should not be done by anyone. It’s possible, though, and if you accept abundant time on your hands, you can actualize admirable agent cartoon that are additionally real, alive genitalia in Fritzing.

Supporters of Fritzing say its greatest backbone is that it’s an accessible apparatus to use, and advantageous if you appetite to whip up a quick PCB for prototyping. They are correct, so continued as all the genitalia you appetite to use are already in Fritzing’s amount libraries. It is accessible to actualize genitalia from scratch, but this is a assignment that could be done faster in actually any added PCB architecture program. What we’re attractive at actuality is a belted garden problem, and for the additional best accepted Accessible Source PCB architecture software, this isn’t accomplishing Fritzing any favors.

It should be noted, however, that abounding of the tasks appropriate to accomplish a Fritzing allotment can be automated. PCB and schematic aisle can be auto-generated. In theory, a simple command band apparatus could tie these genitalia anon to breadboard footprints. If anyone wants to accord to Accessible Source in a allusive way, there’s a activity for you: accomplish a apparatus that takes an SVG of a dent or basic and turns it into a Fritzing part.

Closing out this tutorial, I’d like to acknowledge [Arsenijs] who created the aboriginal tutorial on authoritative a Fritzing allotment over on Hackaday.io. [Arsenijs] did this because I put up a compensation for the aboriginal adviser to authoritative a allotment in Fritzing from scratch. Not alone do I accord to Accessible Source (which agency I’m bigger than you), I accord to Accessible Source documentation. I am a unicorn that lays aureate eggs.

That’s it for Fritzing. I’m not affecting it again. For the abutting column in this Creating a PCB in Everything series, I’m activity to booty a attending at the cloud-based PCB architecture tool, Upverter. Will it be bigger than Fritzing? Who knows. Maybe. Probably.
