Are there any refresher courses in MK programming?

Question

Microcontrollers

At work, I was instructed to find courses on programming microcontrollers. As for the specific controllers, I did not understand, but it seems like 8051 will be. There is programming experience for the 51st core.

Does such a thing exist at all? Preferably in St. Petersburg. Superficial googling has yielded no results.

To the extreme, any courses on MK programming, even if they just tell the basics of MK and then they will give a crust.

Thanks in advance.

Answer 1

I already thought that 8051 was old and forgotten like a bad dream, but no. People are looking for courses for them. Horror ...
And if on the subject of the issue, then various large companies, suppliers of electronic components, conduct such seminars and courses. Subscribe to your suppliers' mailing lists and be the first to know about such courses.

Answer 2

I have not seen full-fledged courses, only reading application notes.
I really liked Energy Micro, everything is described in a very simple and accessible way.
