It's usual to have something like this, in setup() :


- but there's an optional second parameter, called config, which has more options, so you can set things like parity, number of stop bits, and so on, by choosing a configuration off a list of alternatives.

Here's the official arduino reference page, which hopefully also corresponds to how it's done in STM32 arduino:

You can do the same with other serial ports (Serial1, Serial2...), but you may need to declare them first, specifying the pins they use.

If you meant setting which hardware clock or timer is used... I have no idea :) I suspect it's automatic, and fixed.

The config for the Serial speed is made automatically using the
