Tutorial 06 - 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.h, rand.c

rand_init() initializes the hardware.

rand(min,max) returns a random number between min and max.

Main

We query a random value and then we display it on the serial console.
