What kind of feeling is it to learn STM32 single chip microcomputer well?

Anyway, I didn't learn it well, mainly because I didn't upgrade to the operating system, but I feel that the function of STM32 is indeed much more powerful than 5 1. Transplanting file system, GUl graphical interface, JPEG image decoding, these resource-consuming programs are all cool, of course, thanks to on-board RAM. Even if you don't need external RAM, you can perform GPS decoding, calling, texting and other operations, trigonometric function operation, and define a large number of double-precision floating-point variables with small memory.

There are also popular elements such as USB control camera, CAN and SDI interface, which will make you feel by going up one flight of stairs.
