Felix Posted September 15, 2012 Report Share Posted September 15, 2012 the arcade wing schematics show pin 7 as 5volts. is that actually done that way? also is that some vhdl setting a port high oris that off some bus run from a regulator or something?i was wiring up a custom controller and noticed that on the schematicsand couldnt see why, unless you are trying to keep compatibility/planning forfuture sega genesis controller supportam at work for next few days so wont have a chance to check the vhdl tosee if i can turn that off or not, and use it as a normal button to allowfor games like superglob to work.regardsfelix Link to comment Share on other sites More sharing options...
Jack Gassett Posted September 24, 2012 Report Share Posted September 24, 2012 Felix,Sorry for the late reply,I designed the joystick portion based on information found here. According to that site some joysticks that have features such as fire autorepeaters use the 5V to power their circuits. I connected pin 7 directly to the 5V power rail so there is nothing that can be done in VHDL to change that behavior. In the new arcade megawing design I changed it to accommodate sega controllers. Pin 7 is connected as I/O and pin 8 is connected as permanent ground so we can maximize our usable I/O. Link to comment Share on other sites More sharing options...
