Activating GPB7 (R2 / SIG) on MCP23017 for coin acceptor

[slayeryea]

Hello,
I've installed the mk_arcade_joystick_rpi and I see that GPB7 which is used for coin acceptor on MCP23017 was not activated.
Where is the setting file to enable that? I have to activate GPB7 for coin acceptor on the MAME
Thanks

the coin is mapped on select. Are you having trouble with that ?

The mk gpio driver of the recalbox doesn't support mcp23017. You might recompile the master branch of https://github.com/recalbox/mk_arcade_joystick_rpi in recalbox to have it enabled.
Or develop on 4.1 a switch for the gpio drivers

@digitaLumberjack so how should i connect the coin mech to standard GPIO (https://github.com/recalbox/recalbox-os/wiki/GPIO-controllers-(EN))?

Thanks
