@Dragu I did not fully understood your schematic, i already bought the relay and now I'm planning on getting the PCB to create the interface. I believe i understood the philosophy behind. Basically you insert one token and it flags on both encoders. But in that scenario 1 coin gives always two credits. So if this thinking is correct you would be fine to use @tong-man solution with a split wire at the end, so I can connect to both GPIO pins, no?

Hello @tong-man, i noticed that the link mentioned above was developed by you and reference on your youtube channel. I noticed that your bartop as two players. So my question is: When you insert a coin your credits are assumed as 'general credits' and both players can take them?

Thanks in advance for the support.

@kjbstar Thanks for the input. I´m afraid there is no way to use a single coin acceptor to replace both buttons. If there is any other information that someone can have will be welcome.

Gents,

I’m building a arcade table using Recalbox. My system is fully working. I was thinking on adding a coin acceptor to it for fun. But I could not found any thread on this matter. (Inlight me if already exist)

The current setup has two players and uses a two independent buttons for insert coin on each player. What I want is to replace this buttons by a single coin acceptor?

I know that is possible with retropie in parallel with a zero delay card. However, I want to connect it through GPIO. Probably I would need to have an independent energy source as it is 12v.

Thanks in advance for the support.

@DCLAIRAC Ignore the above is sorted the wiring will test and post my feedback. Is much simpler than both of us thought I believe, if we understand the micro switch schematic NC (normal closed) vs NO (normal open)tells you everything.

@dclairac thanks for the support.
And apologize for the late answer but as I work offshore no access to the normal world.

So basically we have just to test with a multimeter and understand the impulse constant or partial.

I never used the multimeter, read a bit and understand that if we set it up incorrectly we may end up burn it. Can you let me know the setup used and the test performed?

Regards

Ivo

@Substring i'm still troubleshooting the system there are the following situations occuring:

1. Mega drive - I need to use a conbination of 2 buttons to do what we would do with a single button on a normal pad. (e.g. Street of rage - to punch i need to : hold B + A.)
2. SNES - When i push a button the action keeps going (e.g. Bomberman, when i place a bomb. As soon it explode it automatically set a new bom without pushing a button)
   This occurs on DOOM as well if i fire a shoot it continue firing util is out of bullets.
3. Neo Geo it goes to the game, blue screen it returns without working.

@substring as i will travelling home at that time can we make it sat**day (11th)? Or sunday.

Wiring you mean positioning within the GPIO? If that would be the case we still would have the response when mapping. And the problem is that some of the games work and the buttons work..

@substring was 4.0 because I could not found roms... so i was using a compile file to try some games.

Changed to the 4.1 and did the support archive, same problems regarding the mapping. (https://file.ac/DaGZwV_MA-U/)

Can we discuss roms subjec on Kiwi IRC? Let me know when suits you.
