G+_Stephen Vincent Posted September 28, 2015 Share Posted September 28, 2015 Been working on a Mame arcade controller build. Probably going to make up a video showing how I did everything and layout a custom PCB to use as the control interface. Right now it has an arduino leonardo with solid wire pushed into the inputs which is a less than permanent solution. I will also probably be applying wood veneer with a vacuum press Link to comment Share on other sites More sharing options...
G+_Scott Youngquist Posted September 28, 2015 Share Posted September 28, 2015 I would love to see a making of video, I've been thinking about doing this and would like to hear your about your experience. Link to comment Share on other sites More sharing options...
G+_Stephen Vincent Posted September 28, 2015 Author Share Posted September 28, 2015 the keyboard emulation function on the arduino leonardo is working very well so far for this application. The only downside is there is only 20 digital inputs which is taken up by the 12 butons and 2x4 each for the joysticks. I am going to add a second leonardo and usb hub to handle the additonal inputs of 1p-start, 2p-start, and 1p-coin, 2p-coin Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted September 29, 2015 Share Posted September 29, 2015 This is awesome! For the extra buttons / digital IO, have you thought about just expanding with I²C? I don't have any experience with it, but from what I understand it's pretty simple and extremely expandable. http://playground.arduino.cc/Code/I2CPortExpander8574 Link to comment Share on other sites More sharing options...
G+_Stephen Vincent Posted September 29, 2015 Author Share Posted September 29, 2015 Might have to consider that, I plan on laying out a custom board with an atmega32u4 and lots of screw type connectors or molex connectors to make wiring much simpler Link to comment Share on other sites More sharing options...
G+_Marvin Bricker Posted September 29, 2015 Share Posted September 29, 2015 look great, would like to see the video as well, thanks. Link to comment Share on other sites More sharing options...
