The question is "how to begin?"
For most simple studinng learn the firmware library. It is no impotance to learn architecture of controller at first.
So you can see the file STM32-lib_manual.pdf
and there is a lot of examples of using any pereipherial on your computer here: C:\Program Files\Raisonance\Ride\Lib\ARM\STM32F10x_LIB\examples
If you want "LED blinking" learn the GPIO examples.
