Arduino for STM32

Got it. Thank you.

I've tried that.

And I got the following error:

Arduino: 1.8.19 (Windows 10), Board: "Generic STM32F4 series, Generic F401CC, STM32CubeProgrammer (DFU), Enabled (generic 'Serial'), CDC (generic 'Serial' supersede U(S)ART), Low/Full Speed, Smallest (-Os default), Newlib Nano (default ...

Hello, Everyone.
I'm working on a project that requires the STM32F401CCU6 to generate truly random numbers.
Is there a way to do it in the Arduino IDE? And if there is, please give me a code that does it.
I tried to use the code from the STM32F407VET6 for that purpose, but it won't even compile.

Midbar (STM32F407VET6 Version) V2.0 is out.

You can find the tutorials for it on:

Hello, everyone.
My name is Max. I'm a computer science student and a self-proclaimed embedded system developer. I began learning to code in 2017 but only started making more or less complex and functioning projects around 2021.

As for the projects, let me introduce you to my most recent project ...

Got it. Thank you so much.
It works.

Hi, I know It's a bit too late, but still, here's the library.
https://github.com/GyverLibs/EncButton
I've actually used it in two of my projects involving STM32F401CCU6.

You can also use HAL directly:

First HAL RNG have to be enabled, to do this, simply add a file named "hal_conf_extra.h" and add this:

#define HAL_RNG_MODULE_ENABLED

Then the code:

RNG_HandleTypeDef hrng;

/**
* @brief RNG MSP Initialization
* This function configures the hardware resources ...

Ok, thank you.
That document gave me a very vague understanding of how the RNG works (in theory).
But still, I don't know what to do with it in practice.
