(Not that I have anything to say about it!)
I threw together some code for my Outrageous RETRO just for fun.
I am providing the code here if anyone wants to try it.
Not sure if it is good enough to post on mbed. Besides, I don’t know how :-[
Not sure if the code is in anyway structured as it should be but it seems to work…
//NOTE: For some reason: Sometimes I do not see Portable Devices CRP DISABLED when I reset the RETRO.
//Going to Device Manager and selecting 'Scan for hardware changes' corrects the problem?
//Using WIndows 8.1 Pro
//The RETRO LCD display code used in this application was developed by Chris Taylor (taylorza) <- This man is AMAZING!
//SPI based library for the ST7735 LCD controller
//See http://developer.mbed.org/users/taylorza/code/ for the current release
//I know nothing about payouts on a 'real' slot machine so I just made some up...
//Be creative and make your own!
//Been to Las Vegas many times but always for work related. The most I ever lost there was about $50.00 and went home happy!
