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 🙏

@pamoja/field-io

The wires a gateway actually has: framed serial packets, an RS485 request and the reply it draws, a CAN frame, the address a chip answers on, and the bus that carries a driver to the part.

One install for the 5 capabilities of this domain. Each is also its own package, and pamoja is the whole framework in one.

npm install @pamoja/field-io

| Capability | Package | What it covers | | --- | --- | --- | | Serial framing | @pamoja/serial | SLIP and COBS byte stuffing with streaming decoders, so a UART byte stream carries discrete packets | | Modbus RTU | @pamoja/modbus | Modbus RTU requests and replies with CRC-16/MODBUS for RS485 field devices | | CAN and J1939 | @pamoja/can | CAN 2.0 and CAN-FD frames with 11- and 29-bit identifiers, plus J1939 decode and compose | | I2C, SPI, and GPIO | @pamoja/gpio | I2C address frames with reserved-range checks, the four SPI clock modes, and active-high or active-low pins | | Buses | @pamoja/core | The embedded-hal traits every driver takes, a bit-banged 1-Wire bus, scripted buses that play a part's side of a conversation, and the Linux backends over i2c-dev, spidev, and the GPIO character device |

The guides, with a worked TypeScript example for each, are at https://pamoja.molex.cloud/docs.
