I have recently begun working more with STM32 processors coming from the more simple Atmel 8bit variety. The Atmel datasheets are very nicely laid out -- specifically speaking to how they provide information relating to hardware configuration registers.

enter image description here

However, I am having a difficult time finding similar information in the ST datasheets. How, for example, do I find information about configuring the alternative options on a pin, or the sampling rate of the ADC? I can find only general information about this hardware for a given processor, but never as much detail as provided by Atmel shown above.

Am I just looking at a condensed datasheet? I pulled one available directly from mouser: see an example.

    \$\begingroup\$ Go to the ST site, and you will find a page similar to this: st.com/web/catalog/mmc/FM141/SC1169/SS1295/LN1808/PF259971# which will have all sorts of technical documentation. If it exists it is probably on the ST site. edit - hit the design resources tab, forgot that it doesn't link to the tab \$\endgroup\$ – I. Wolfe Dec 14 '15 at 21:38

To get the detailed info including register map and other register details for an ST microcontroller, you want what they call the reference manual, not the datasheet or the user manual.

See for example:

  • \$\begingroup\$ Yes, I too was looking at the condensed datasheet. Not be confused, ST of course calls it the "reference manual". \$\endgroup\$ – Leroy105 Jan 17 '18 at 17:00
