Tutorial 08 - Hardware Random Number Generator
This going to be an easy tutorial. We query a number from the (undocumented) hardware random number generator. You can use this to implement a simple, but accurate dice throw in any game. It is important as without hardware support you can only generate pseudo-random numbers.
rand.s
Due to lack of documentation, we mimic the respective Linux driver.
Rng::init(&self)
initializes the hardware.
Rng::rand(&self, min: u32, max: u32)
returns a random number between min and
max.
main.rs
Press a key to query a random value and then display it on the serial console.
