STM32 Nucleo and mbed

Hello everybody and thanks always.

This time I would like to ask if someone has tried mbed to program a STM32 Nucleo board.

I have one (STM32F091RC) and I have used mbed to program a couple of examples (LED switching, using a button, etc- basic stuff)
Now the programs seem quite simple.

However I have seen (not tried) programs for the STM32 architecture, and although they are understandable (I am quite fair at C I think), they are much more complex than the ones in mbed. They usually require input/output initialization, etc which is not something I am complaining about since I can do it, but it calls my attention

Why are the mbed programs so simple?

Can I do serious development with that platform??

Any other experience with mbed or STM32?

Thanks in advance

You'll get to a point where your on your own..... Here at ETO we have members that have done things and share their experiences....

The issues that I have haven't been written.... Reading and understanding takes over... I have looked at MBED but I have chosen my own way forward..

I found a very good article dealing with this kind of things. I ll leave it here for anyone interested in mbed or STM32.
(I also did my first program: controlling a 7seg! )
