My Haas tech had originally set up my WIPS spindle probe as T31, however I wanted it in T1 to match my other machines.

EtherCrab 0.7.0 (lib.rs) is out as the next release of this pure Rust EtherCAT MainDevice!

EtherCrab 0.6.0 (lib.rs) is out as the next release of this pure Rust EtherCAT MainDevice!

This is an answer to this StackExchange question which I'm posting here instead as I refuse to add any more of my time or energy to that website.

I've just released EtherCrab 0.5.0 (lib.rs), the pure Rust EtherCAT MainDevice.

The TLC5940 is a "16-channel LED driver w/EEprom dot correction & grayscale PWM control" IC, used for driving up to 16 constant current outputs (typically LEDs) using a number of control lines.

EtherCrab 0.4.0 (lib.rs), the pure Rust EtherCAT MainDevice is out!

I recently got a pretty neat all-in-one air conditioner to heat my frigid Scottish garage in the winter.

An update on my previous guide for LM 19.3 on how to set up a LinuxCNC simulator on Linux Mint 21.3 Virginia.

In working on ethercrab I found myself down the rabbit hole of trying to reduce binary size, in this case for the thumbv7m-none-eabi architecture used in embedded.

The EtherCrab story started with my dream of writing a motion controller in Rust to provide a modern alternative to the venerable LinuxCNC project.

I got a Ryzen 5625U Morefine S500+ Mini PC from Aliexpress for EtherCrab development recently.

During the creation of EtherCrab, a pure-Rust EtherCAT master, one of the core structs in the crate started growing quite a few const generic parameters.

A quick PSA in case you're at a loss as to why you're seeing strange behaviour from your STM32 MCU pins when running higher frequencies through them like I was.

A quick update on my previous article.

Welcome to another pointless tangent into the exciting world of line joints in embedded-graphics!

Graphics can be a tricky topic, particularly when attempting to find anything on the internet these days that provides solution in terms of integer-only maths. embedded-graphics is a (mostly) integer-only library, so in pursuing a solution to good line jo…

CNC jog pendants are super useful devices for quick setup and configuration of CNC machines.

I'd like to announce two crates I've been working to integrate Rust components into LinuxCNC.

This guide has been upated for Linux Mint 21.3.

Version 0.5.0 is released!

We're building a new product at work, for which we've decided to use Rust and tower-web for the backend.

I maintain the Repositive website which uses React for the frontend and a server that supports server side rendering for the speed and SEO benefits of SSR.

Embedded graphics 0.4.7 has been released, along with a new sister crate, tinybmp!

I've recently been working on a Rust project at work which requires compiling for Linux (GNU), Linux (musl - for Alpine Linux) and macOS.

Similar to the SSD1306 covered previously, the SH1106 OLED display is a small, self contained module perfect for hacking into a project or prototype.

Rust (and LLVM) are really good at optimising things.

In my other post about creating properly typechecked helper functions in Typescript, I missed something out from the examples that's present in the real code: default parameters!

I've been working on toasting a lot of our tech debt at Repositive recently.

Install Evolution with the Exchange addons apt install evolution evolution-ews evolution-plugins

As part of the weekly driver initiative, myself (@jamwaffles), @therealprof and @scowcron have been working on a Rust driver for the common as mud SSD1306-based OLED display modules.

I've been developing an embedded Rust app (yay!)

So.

Cloning a private Github repo using SSH auth in Rust has proved to be a pretty gnarly problem (for my anyway), so I thought I'd share this quick tutorial to help anyone else out that might be struggling with the same issue.

One of my main responsibilites at TotallyMoney was to take care of the in-house analytics/event logging framework.

In between watching the rain and emptying all the shmoo out of my air compressor (long overdue), I decided to try my hand at some impromptu scraping this weekend.

Here's a quick one; I'm making a Christmas display out of a bunch of serially controllable APA106 RGB LEDs, but how do I turn a value of 0 – 255 into a glorious RGW (Red Green White) struct with the correct colour, and the correct wrapping rules?

I'm fascinated by Rust for it's safety and speed, but also because it's simple to write low level code in what feels like a high level language.

Quick tip: if you're looking for higher maximum speeds with your bipolar stepper motors, try wiring the windings in parallel instead of series.

Huanyang branded VFD drives are ubiquitous on eBay and other sites like AliExpress.
