Create a serial-connected Espruino device.

import { Espruino } from 'https://unpkg.com/ixfx/dist/io.js'
const e = await Espruio.serial();
e.connect();
Copy

Options:

import { Espruino } from 'https://unpkg.com/ixfx/dist/io.js'
const e = await Espruino.serial({ debug: true, evalTimeoutMs: 1000, name: `My Pico` });
e.connect();
Copy

Listen for events:

e.addEventListener(`change`, evt => {
 console.log(`State change ${evt.priorState} -> ${evt.newState}`);
 if (evt.newState === `connected`) {
   // Do something when connected...
 }
});
Copy

Reading incoming data:

// Parse incoming data as JSON
s.addEventListener(`data`, evt => {
 try {
   const o = JSON.parse(evt.data);
   // If we get this far, JSON is legit
 } catch (ex) {
 }
});
Copy

Writing to the microcontroller

s.write(JSON.stringify({msg:"hello"}));
