I looked at this thread already -
However, my question is a bit a different. I want to focus on more of a learner/beginner's perspective. As the other thread also mentioned, the development kit makes a huge difference, and more so for beginners I believe.
Although, the choice of development kit is an opinion, I would like to know what kit has the most support? (In terms of volume). I tried to look it up, but could not find anything conclusive. I suspect its the Keil kit given it was bought up by ARM, but I am not sure.
Also, is there any data on free vs paid kits and the amount of support they provide?
The second part of my question is, what dev. boards are good for beginners? Since, the main aspect is learning to program an M3, not performance - i suspect, there are cheaper options available for playing around. I found a couple, namely in the ST32 category and another board called Matchbox, however I could not find anything conclusive. I was looking for evidences like this particular chip is used in universities to teach a course etc. (I looked up a few university course pages as well).
Any help is much appreciated!
