Another demo that I saw while at the Freescale Tech Day was also pretty simple, but already moving a step beyond the traditional Arduino examples. It’s just blinking a LED, but rather than the “brute force” approach of switching the pin then forcing a wait before switching it again (the algorithm in the classic Arduino …

A few days ago I wrote about a “learning timer” that I had built using an Arduino Uno. Arduino boards are pretty easy to come by, and also easy to work with, but can be a bit expensive to build in to things (a genuine Arduino Uno from the manufacturer will set you back 20 …

After my previous post on delimiter-free languages it occurred to me that the idea of txtzyme has merit for communication between some of the devices I have to hand. Some while ago I spent some time producing some bare-metal code examples for the Raspberry Pi (flashing morse code, GPIO control and uart stuff, for example), …
