Teensy as two gamepads?

[vitormhenrique]

Is it possible to make teensy show up as two different gamepads?

I'm trying to get a custom built arcade machine to work, but I'm having difficult to configure two players with the same gamepad. Retropie and Recalbox expect two different gamepads for two different players. I dont want to use keyboard because of the 6 keys limitation.

Thank you for the help,

I think I figure it out, I basically created a new variable inside of the usb desc with the same information of the joystick, than I created a new USB_ARCADE based on the USB_HID and added my new joystick configuration.
I cloned the joystick class and created joystick1, and that is it! I now see two interfaces and both are getting button presses on windows.
Now it is a matter of see if recalbox accept the configuration....

Not something I've tried and looks like you have it well in hand but if there are any loose ends in the project

is a fairly good overview of the changes needed to make a new USB classes.

I got it showing as two devices, but both joysticks will have same ID and the OS don't handle that pretty well. Ended up using two teensys-lc and synchronizing the code, I "needed" to have one teensy display led patterns when buttons where pressed.
