SWO logger from M5STACK

Hi all, a short update on SWO logger. I managed to implement a very basic SWO data logger based on M5STACK device. Looks nice and works well (see the picture below where my test setup is shown). I have to admit though, that this thing turned out to be not as simple as expected. Now it needs some real-life testing. I’ll use it for some of my future projects and let you know about my experience. I hope it worth the time spent on it.
