Electronic Dice for the SPB

Post by bitfogav » Thu Sep 13, 2012 7:36 am

Since I got my SPB I often thought I had to make something for it!, untill just recently I haven't found the time to look at the full workings of the SPB board apart from the day when I built the kit from iteadstudio.

I know this isn't anything new an "Electronic Dice", but its surely new to the SPB :lol:

So heres my version of an Electronic Dice for the SPB :) I've reused some code from the SBP for controlling the matrix, why change something that already works!?. It also includes some sounds from the Monofonic audio chip!.

Its simple to operate, the electronic dice starts up on the title screen simular the Brads SPB game and plays a song, to start the electronic dice you press button B, once started you just have to press button B again to start the dice rolling again. on each dice roll a random FX sound from the Monofonic audio chip will play and the dice will roll. to exit back to the title screen you just press button A.
Ive also made it so you can turn the sound off by pressing and holding the down button whilst powering on the board.

The code uses a Random Generator (RandGen2) simular to the one that Brad uses in his SPB game, but this version is slightly different, it allows us to get a random number between 0 to 6, this was used to then select the number on the dice, Ill include the randgen2 below.

The Dice value will be shown on the LCD aswell as on the matrix as some Dice patterns.


This is the title screen:

I've said this before and I'll say it again - very cool bitfogav!

I especially think it's great that someone has done something extra with Super Pixel Bros.

What we should do is put in an accelerometer then you can literally throw the SPB board and the accelerometer will start the dice rolling. Although you would need to make sure the screen always landed the correct way up...

Which ones? I bought a couple that are great (haven't done much with them yet) but they simply have three analog outputs for X, Y and Z. they can vary from 0v to 3.3v depending on how each axis is tilted :)
