Pinout Generator

A very work in progress pinout diagram generator using Python and drawsvg

Usage

Config Files

Configuration can be split across multiple config files to allow for sharing of common properties

"_style" fields are standard SVG properties like fill, font_family, etc.

Define types

types:
    pin:
        width: 80
        description: PIN NAME
        box_style:
            stroke: black
            fill: grey
        text_style:
            font_family: Roboto Mono
            fill: white
    ...

Define pin functions

pins:
    PIN1:
        - type: pin
            name: PD7
            alt: False
        - type: spacer
    ...

Map Pins to physical output on IC

mapping: [PIN1, PIN2, ...]

Styling

See the default files for further reference

pin: !include ../defaults/pin_qfn.yaml
label: !include ../defaults/label_qfn.yaml
package: !include ../defaults/package_qfn.yaml

Chip options

footprint: QFN-20 #Footprint-PinNumber
name: "IC NAME" 
subtitle: "SUBTITLE"
package_text:
  text: "ON PACKAGE TEXT"
  sub_text: "ON PACKAGE SUBTEXT"
canvas_width: 2000
canvas_height: 1000

Generating the Images

To generate a single Image

 py pinout.py [yaml file] [output file]

To generate a whole directory, first characters of yaml files should match directory name. SVGs will be saved in the directory

 py generate_dir.py [yaml dir]

TODO

• Error checking
• Documentation
• Improve SVG generation
• Add different styling options
• Added YAML functionality like Homeassistant and ESPHome has
• Improve modularity to allow for more complex footprints
• Clean up a lot of bad programming and improve readability
• Use config files and cli
