Want to add my own controllers

[chr1s-t0pher]

which files will i need to modify in order to add another gamepad? like nvidia shield gamepad vendor_id = 0x0955 and product_id = 0x7214 or my amazon firetv gamepad vendor_id = maybe 1949 and product_id = maybe 0402

would copy probably the xbox_one_controller.c and rename all to shield_controller, but which other files do i need to modify? and than i would test it with Controller Test by brienj

I can build files i setup devkitpro.

more familuar with c sharp and python.

You'll have to create a new .c file for a controller in source/ios_pad/source/controllers. You can base this file on one of the existing controllers. In the controllerData function you'll need to parse the incoming input reports and set the values in reportData accordingly. Stick values should be normalized between -1140 and +1140.

Then you can add the controllerInit function declaration after the other declarations here: https://github.com/GaryOderNichts/Bloopair/blob/9ce7b47be0d5dd1f597b406e97c28d15bee56d87/source/ios_pad/source/controllers.c#L113 and add a branch for your vendor and product IDs like this one here: https://github.com/GaryOderNichts/Bloopair/blob/9ce7b47be0d5dd1f597b406e97c28d15bee56d87/source/ios_pad/source/controllers.c#L186

Sorry for the late reply. Did you test the code and it's fully working? Are there any references for the reports of this controller? Seems a bit odd that it also uses report 2 and 4 for home button presses and battery levels. If everything works, could you open a PR for it?

[chr1s-t0pher]

Battery level not tested, used "Hid Demo" from SharpLibHid to figure the hex codes out. Buttons, direction buttons and analog sticks work, all tested with a tool for the wii u, also played a couple of games.

Bis jetzt funtioniert alles, aber weiss noch nicht wie ich die lampen ansteuere und rausbekomme wie voll die Batterie ist.
