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.

node-vl53l3cx

nodejs module with native bindings to the VL53L3CX API provided by STMicroelectronics as part of the stm32duino project (https://github.com/stm32duino/VL53L3CX)

The original API code is designed to work within the Arduino environment, and uses Wire.h as the interface to the i2c hardware. To make this work under standard Linux environments, all i2c related code is replaced by standard ioctl methoods. Some changes to the original constructor were also required to save the ioctl file descriptor rather than the Wire.h reference. Also changed the constructor to not require any passed variables, so it can be stored in a map construct for use between the initSensor and readSensor functions.

Some other bug fixes were required, especially in the VL53LX_init_and_start_range, where it was found with a full configuration reset that it overwrote the previously set VL53LX_I2C_SLAVE__DEVICE_ADDRESS with 0, causing the i2c interface on the device to hang. Also have added a call to VL53LX_software_reset in the initialisation process, rather than relying upon toggling a GPIO connected to the hardware reset/XSDN_I pin.
