F1 Series Beginner Steps to enable peripherals

[jdsus]

So I’ve been following a udemy course and I’ve been picking things up and learning how to change registers for peripherals and how to enable them and such but the course just tells me what I need to enable bit wise to enable the specific peripherals but I just had a thought, if I didn’t have this course, where would I find what I need to enable? Is it in the data sheet and I’m not looking hard enough? Like for gpio I need to enable the port clock before I can configure specific pins

Hi @jdsus 

Peripheral clock gating is specific to the STM32 architecture, and by default all peripheral clocks are switched off.
See section 5.3.2 Peripheral clock gating in RM0008 for an explanation.
