4.4BSD UNIX™, the last version to be written at Berkeley UC. Shown here with vintage keyboard and vintage monitor, and 3 microcontrollers to glue it all together.

I have just constructed this PIC32 microcontroller based serial terminal on veroboard. It supports a PS2 or USB keyboard, and drives a VGA or composite video output.

But will it work?

My home designed & built Microchip #PIC32 based #Unix Computer. This tiny board runs 4.4BSD UNIX™ last written at Berkeley, shown connected to a terminal via a serial port. This OS required a room full of VAX hardware back in 1978.

My completed wireless Internet of Things scrolling Messager. It displays live news feeds, local weather forecasts and other useful information in real-time.

An uber low tech retro game I wrote for a 16 x 16 LED matrix. Wow check that resolution!

Homemade wireless #IoT #NewsFeed messager. Uses an old LED display that probably was originally in a hospital or railway station. Now modernized to the internet age with live news and weather feeds. Firmware written in C++.

Just published my tiny USB DFU bootloader for the #pic32 under https://github.com/kiffie/kiffieboot. A runtime support crate in #rustlang #embedded will come soon.

Blink An LED On a PIC32 With Rust, Easily

Got a PIC32 microcontroller and a healthy curiousity about the Rust programming language and its low-level capabilities, but unsure how to squash the two of them together with a minimum of hassle? If that's the case, then today is your lucky day!

[Harry Gill] has you covered with his primer on programming a PIC32 with Rust, which will have you blinking an LED in no time. [Harry] admits that when he got started, his microcontroller programming skills were a bit rusty, so don't let yourself think setting this up is beyond your abilities. If you have a working knowledge of the basics of microcontroller programming, you'll be fine. [Harry] had to jump through a few hoops to get the right tools working, but thoughtfully documented the necessary steps, and provides a bare minimum hardware list.

Unsure what Rust is or what it offers? Check out the basics here, and see if it's something that interests you. If you want to look even deeper, check out the kind of work that goes into writing a bare metal kernel in Rust.
