Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

emic-bus — EMICBus V2 desde Node

Port a TypeScript, byte a byte, del protocolo EMICBus V2 del editor web (EMIC.Web.IDE/wwwroot/js/ide/emicbus-v2/, a su vez port de EMIC-CLI/Services/Serial/V2/, verificado en hardware): COBS, CRC16/32, tramas largas y cortas (incluido MSG_SRC), Intel HEX PIC24, el cliente del programador V2 y un transporte serie sobre serialport hacia la pasarela V3. Lo usa emic-mcp para las tools de hardware; el editor sigue con su copia JS.

import { openGateway, MODE_PROGRAMADOR, loadWords, extractEntry, hexLinesOf } from "emic-bus";

const gw = await openGateway(undefined, { mode: MODE_PROGRAMADOR }); // resuelve el puerto (VID 04D8 / PID 00DF o sonda)
try {
  await gw.client.resetSystem();
  const modules = await gw.client.listenAnnounces(3000);
  const words = loadWords(hexLinesOf(hexText));
  await gw.client.assignId(modules[0].uid, 0x3e);
  const info = await gw.client.info(0x3e);
  await gw.client.sessionOpen(0x3e, modules[0].uid);
  const result = await gw.client.programApp(0x3e, words, extractEntry(words)!, info!.appStart, info!.appEnd, "Pres", "Termo");
  await gw.client.sessionClose(0x3e);
} finally {
  await gw.client.setMode(MODE_PASARELA); // todos corriendo
  await gw.close();
}
  • Link es la única abstracción del transporte (send, poll(ms), clearInput): NodeSerialLink para Node, o un link falso para tests.
  • serialport se importa en diferido: el núcleo del protocolo no carga el binario nativo.
  • Tests: npm test (vectores del selftest del editor + cliente contra un link guionado + link con un serialport falso).
