Let's take a look at the timer structure diagram first

Fudan Micro's timer structure diagram

Hey, I think we've met somewhere before

At first glance, it feels really familiar. It feels like déjà vu.

Quickly open the ST timer structure diagram

This can't be said to be similar or not

Exactly the same

Okay, then timer programming isn't a big problem.

Let me make a PWM first

I couldn't find the PWM output after searching for a long time. It turns out that the manual was wrong and the output was input.

Look at the PWM output configuration code of STM32F0

Look at the structure definition

Fudan Micro

ST

Let’s take a look at Fudan Micro

It's basically the same, no major changes

The only difference seems to be OCFASTMODE , which ST does not have. Let's see what function it has.

So I went to look through the ST manual

OK, I am superficial, ST also has this function

The difference is that this function is made into a library function in ST

Waveform:

The timer is like this, basically the same, there are some differences in function encapsulation and structure definition

Jacktang

Exactly the same

It can replace stm32

But to completely replace the estimate may still need to be verified

Why do I feel that Fudan Micro's pictures look more comfortable than ST's?

Only the timer is similar to ST's, other modules are still different

The timer module is applicable, but the others have not been tested yet, right?
