Hi Amelia, I don't know the name of your wonderful Polish accented Applications Engineer who presented the STM32 HAL section of your MOOC, so let's refer to him as "ADAM" until I learn his real name.
I was so impressed with ADAM'S style (thoroughbred engineering) and subject matter (hands-on, real code), that he set an excellent standard for the remainder of your team to meet or surpass.
The other presenters (with one ot two exceptions) seemed more interested in impressing the ST management with a slick, marketing oriented and sales approach which rendered even watching it as a time wasting and frustrating exercise for "how to" knowledge seekers. Simply presenting part overviews of block diagrams and quoting specs. which are often even highlighted in part spec. sheets seems wasteful and not newsworthy to me.
Perhaps the problem is my grumpy old impatience, but I did truly enjoy (and I also recorded) "ADAM'S" great practical presentations - even gis side comments were crumbs of inspiration. I am a very experienced presenter from my days in Defence as a Research Scientist, where we had monthly colloquia where we presented our work progress. Not many of your presenters would be taken seriously as truly technical, simply 'hand waving' and gesturing.
I hope that I have not been too negative and crude and that my comments are considered as helpful. The message is " keep focused on technical how-to knowledge with your great products", they have degraded into technical sales pitches.
I sincerely hope this is helpful for you. If I can be if any assistance, please feel free to ask me as I am retired and have a big place in my heart for ST and a few other producers of quality electronic components.
Cheers Alexandre, Peter Kelly.
PS. If "ADAM" agrees, please tell me his real name.
Cheers, p
