Eink library

This small library is intended to allow sending commands to eink devices, although at the moment it only supports the Mira Display from Boox.

It uses the node-hid library to communicate with usb devices. On linux, you would have to either run as root to "write" to the usb device. Or add a new udev rule in (/etc/udev/rules.d/) with:

KERNEL=="hidraw*", ATTRS{idVendor}=="0416", ATTRS{idProduct}=="5020", GROUP="plugdev"

Doing a simple refresh, with dynamic import mode:

import('eink').then(({ Mira }) => {
  const device = new Mira.Display();
  device.sendCommand(Mira.Commands.refresh);
  device.close();
});

Or setting the warm light to max, with ES Modules

import { Mira } from 'eink';
const device = new Mira.Display();
device.sendCommand(Mira.Commands.setWarmLightLevel, 255);
device.close();
