| Fursphere:
I've got a pair of Sinden lights on my cabinet, and I've got them working with RetroArch and MAME. I picked up a pair of industrial foot pedals I'd like to get working for games like Time Crisis. I'm not sure how to go about wiring them up and interfacing them? I've got an extra IPAC-2 USB controller that I can use (seems like a waste for just two buttons, but I've already got it so whatever). Is there any particular keyboard keys I should map them too? Or just anything, and then just map them in game to "pedal" ? Feels too simple... thanks |

(You can't do this with an IPac.) - Wire optos with 5v, ground, Data A, and Data B. (You can do this with a 2015 or newer IPac.) Do you have an Arduino like a Pro Micro lying around? - With the right choice of firmware, it will work with any of the 3 types of pedal components mentioned above. --- Quote from: Fursphere on April 03, 2023, 05:04:43 pm ---Is there any particular keyboard keys I should map them too?

(B, E, H, M, N, etc.) --- Quote from: Fursphere on April 03, 2023, 05:04:43 pm ---Feels too simple... --- End quote --- It's not rocket surgery. ;) :lol Scott |

Sorry, they are microswitch based. Have both NC and NO wiring options. (NO is what I'll be using) Thanks for the info (and the unused MAME key list). Very helpful! Now I just need a small project box. |

I use this code https://github.com/crankyoldgit/mame-ipac-emulator with a pro micro and edit it to have "B" and "N" key that not interfer emulator i 've 3d print this https://www.thingiverse.com/thing:5022017 and buy two pedals from alixpress from here https://fr.aliexpress.com/item/1005001399341850.html |
