You’re kidding, right? Are you just starting your final project with about a week to go in your class?

You’re kidding, right? Are you just starting your final project with about a week to go in your class?

The HCS12 board comes itself with LCD screen so That won't be an external component right! and is there any specific commands to integrate RNG to LCD screen?

The original question was how to solve the project problem “using HCS12 board without using any external components”.

So the answer to this must be “yes if the LCD is on the board and correctly connected” J

Use google and look for pseudo random number generators. It is typically just some multiplies, adds, and modulos with prime numbers.

Use an ARM processor that has a true random number generator device.

Build an external RNG device.
Andrei from The Great White North
(as seen on the embedded.fm podcast and blog)

Since it is a slot machine, how about:

- At power up, create some free running counter that will count with high frequency

- When the Slot machine handle is pulled or button is pressed, read the counter value

Subject: [68HC12] HCS12 - RNG generation

I am trying to build Slot machine through HCS12 board without using any external components. I want to create a prototype of slot machine for that I need to have a working RNG code (may be in C language). give me the idea of where and how to start?

Thank you!
