Posted on August 05, 2016 at 10:20The Reference Manual for your STM32 sub-family is the basic source of information. As an appendix, the 'F0 RMs contain a set of examples for dealing with many of the basic peripherals. These are also contained within a set of examples called Snippets. These don't use Cube, rather, they access peripheral registers directly; symbols for these registers and for related constants come from [Cube]/Drivers/CMSIS/Device/ST/[family]/Include/[model]xx.h, that's the only header you need for this style of work.
I won't help you with Cube as such, I don't use it. It contains a ''GettingStarted'' pdf in [Cube]/Documentation, and then doxygen-autogenerated .chm documents in [Cube]/Drivers/[Family]_HAL_Driver, but I am not sure how useful reading these are. Supposedly, CubeMX (the program, don't confuse it with Cube which is the library) alleviates the need to read any documentation, providing you a clickey code generator, I don't know how well this fits your notion of learning. You might also try to start with simply going through the available examples, under [Cube]/Projects.
Of course, you are supposed to start with the ''embedded Hello world'', ie. a simple blinky.
