Example

Here is an example of how to use the Webserial API to interact with a PinPax device.

import { PinPax } from "@danidoble/webserial";

const pinPax = new PinPax();

pinPax.on("serial:disconnected", (event) => {
  document.getElementById("disconnected").style.display = "block";
});

pinPax.on("serial:connected", (event) => {
  document.getElementById("disconnected").style.display = "none";
  document.getElementById("need-permission").style.display = "none";
});

pinPax.on("serial:need-permission", (event) => {
  document.getElementById("need-permission").style.display = "block";
});

pinPax.on("serial:soft-reload", (event) => {
  // reset your variables
});

pinPax.on("serial:unsupported", (event) => {
  document.getElementById("unsupported").style.display = "block";
});

async function tryConnect(){
    await machine.connect().then(() => {
    }).catch(console.error);
}

document.addEventListener("DOMContentLoaded", () => {
  tryConnect();
  document.getElementById("connect").addEventListener("click", tryConnect);
});

// i don't recommend expose pinPax object since it's a global object and has control over the pinPax
//window.pinPax = pinPax;

      port. Please, click the button to try again.

    <div id="disconnected">
      The pinPax is disconnected. Please, check the connection.
