There was a time when microprocessors were slow and expensive devices that needed piles of support chips to run, so engineers came up with ingenious tricks using extra hardware preprocessing inputs to avoid having to create more code. It would be common to find a few logic gates, a comparator, or even the ubiquitous 555 timer doing a little bit of work to take some load away from the computer, and engineers learned to use these components as a matter of course.
The nice thing is that many of these great hardware hacks have been built into modern microcontrollers through the years. The problem is you know to know about them. Brett Smith’s newly published Hackaday Superconference talk, “Why Do It The Hard Way?”, aims to demystify the helpful hardware lurking in microcontrollers.
