In this final article of three, we're going to make our DMA-based ADC example from the second article run off a timer, and we'll do a small demonstration of how this might be used in a realistic application.

There's a video demonstrating each of the examples covered in this series of articles. It's probably most useful to watch it in conjunction with reading the articles.

In this second article of three, we're going to change our polling ADC example from the first article to use DMA.

DMA is a subject that is unavoidably a little complicated. It's useful to understand what DMA really is to get an idea of where that complexity comes from. That might help to build some enthusiasm to battle your way through the DMA section of the reference manual!

I've been doing some STM32 programming recently as part of my Mini-Mapper project (using an STM32F767ZI). I needed to collect samples from several analog inputs at a fixed frequency, for monitoring motor torque. A simple thing to do, right? But the obvious way to do it isn't necessarily the best.

In this series of three articles, I'm going to try to show a better way. Some of this will be quite boring (it's just configuring microcontroller peripherals, after all), so I allowed myself a bit of time for a fun "finisher" at the end.
