inky

A typescript package to interact with Pimoroni's Inky Impression 7.3. Implemenents a subset of the features of @pimoroni/inky

Features

• Support for the Inky Impression 7.3 (only currently)
• Individual pixel interaction
• Setting images in:
  • PNG
  • SVG (using optional resvg-js dependency)

Usage

Install inky

• npm install --save @aeroniemi/inky

Setup GPIO

• This package uses rpio for GPIO interactions, so you'll need a working install of that
• In particular, you need to:
  • Disable GPIO interrupts
  • Enable /dev/gpiomem access
  • Run as root user (for access to the SPI device)

(Optional) Setup resvg

• npm install --save @resvg/resvg-js
• If you're using a Raspberry Pi 3/4/Zero 2W it'll probably "just work", but if you're on a Zero or Zero W you'll need to compile resvg to get it to run properly. See this issue for more details on how.

Example

Display a PNG

import { Impression73 } from "@aeroniemi/inky"

async function main() {
    let screen = new Impression73()
    screen.display_png("./[IMAGE.png]")
    await screen.show()
}
main()

Display a SVG

import { Inky_ac } from "@aeroniemi/inky"

async function main() {
    let screen = new Impression73()
    screen.display_svg("./[IMAGE.svg]")
    await screen.show()
}
main()
