Brighton Rust: Embedded systems, day 2

Following on from last week, this time we did “blinky”: making the LED flash on the hardware. Once again, Tim kindly led us through this and supplied some additional LEDs and resistors so we could get multiple LEDs flashing.

Brighton Rust: Embedded systems, day 1

The Brighton Rust group has been learning how to run Rust programs “bare metal” on embedded hardware. That is, hardware without any operating system: an Arm chip, some memory, the odd button and a few LEDs.

Tim kindly lead us through “hello world”, and these are my notes on what we did, specifically on macOS. I’ve added in a few comments after ducking around after the event.

In this post I’ll highlight 3 features from Scala.js 1.x that I’ve recently used to dig myself out of a hole.

Headless Raspberry Pi and the Mac: Basics

I only occasionally work with a Raspberry Pi, which means I keep forgetting and having to rediscovery some pretty basic tasks.

This post is my crib sheet for working with a headless Pi…

Getting Into Other People's Code

Two Months with the Findster Duo

I’ve been using the Findster Duo GPS pet tracker for a couple of months. I thought I’d share my experience with it so far…
