This adds mFI as a controller driver for OSX, as well as adding rumble
support for mFI controllers. Also add support for the Home button.
Also fixed a couple warnings.
== DETAILS
I'm going to need to re-implement the abstraction between HID device
and gamepad; the changes here lay down some foundation for that work.
- reduce logging priority of some statements I modified while debugging
- factor out the pad driver lookup into its own method
- fix so the pad driver list isn't re-initialized every invocation
- add the button() method for the GCA driver
== DETAILS
When I first implemented the Wii U HID architecture, I ended up
having to design my own implementation because, at the time, I did
not have a way to read the HID device string to allow the existing
code to successfully detect the gamepad.
After spending some time experimenting, I've figured out how to
do this. And that means I can better align the HID driver with other
platforms.
change summary:
- create a single state structure for all three sub-types of wiiu pads
(kpad, wpad, and hid)
- eliminate confusing duplicate pad lists
- eliminate confusing duplicate HID pad drivers (ds3, gamecube
adapter, etc)
- ensure the ds3 driver still works
== DETAILS
File this one under "I'm not sure how this ever worked."
I mean, it did (in 1.8.8). I'm not sure what changed, but ultimately what I did was
a bunch of comparative testing against 1.8.8:
- I confirmed the packet data was still being read successfully
- I confirmed that the axis value being passed into pad->get_axis() had
not changed
- I confirmed the work done in `gamepad_read_axis_data()` was working the same
between 1.8.8 and master
With the only difference between 1.8.8 and current being the return value from
`gamepad_read_axis_data()`, I just rewrote the method to work properly, and
also fixed up the default axis mapping.
I tested this with a sixaxis controller and GCA, configuring the analog-to-digital
control override to use the right stick.
iOS: change default joypad driver to be mfi
iOS: move autodetect of mfi controller to mfi_joypad driver and set the default mapping for both iOS and tvOS
iOS: support unsupported buttons on mfi controller (select,L3,R3) by using hotkey combinations using the MENU button
tvos: use INPUT_TOGGLE_DOWN_Y_L_R as default for menu toggle gamepad combo
- add tvOS target
- support code signing tvOS cores by adding an argument to the code signing cores script
- use NSCachesDirectory for the documents directory
- add some mfi controller handling logic to set non-game controllers to the last index to avoid interfering with operation
- autodetect mfi controller for apple tv on startup - added autodetect to hid joypad
- added a webserver to transfer files for tvOS
- xcode: clean up project, remove unused folders
- remove HAVE_MATERIALUI setting for tvos build, make it use XMB as default
- added retroarch app icon courtesy of @MrJs
- added auto-detect of mfi controller for apple tv
== DETAILS
- DS3 analog wasn't working mainly because I forgot to actually declare the
axes in input/input_autoconfig.c when declaring the pad. Whoops.
- I also moved the axis decoding logic to a more central place, because it
clearly is not Wii U specific.
- Removed some dead commented-out code
== TESTING
Can use analog inputs on both GCA and DS3. Tested in Mario 3 on Nestopia core.
Haven't tested with any actual analog games, but I did confirm via logging
that the correct ranges are produced.
This should fix the issue where R/L buttons didn't register when doing
input detection.
This also brings the GC pad in line with the rest of the gamepads in
input_autodetect_builtin.c.
Also fixed a really stupid bug that was part of why analog inputs aren't
being read. Analog still isn't working, mind, but it's a lot closer to
working now that it's actually getting down into the pad driver level!
== DETAILS
- fix the bitshift math
- read the right bytes out of the ds3 data packet
- remove verbose logging in critical path
- stop caring about errors in the hid read loop -- seems to just
be benign "device not ready" -- or at least, that's what I'm assuming
given that the read eventually succeeds.
== TESTING
Played Mario 3 with the DS3 with no issues.
== DETAILS
- update to not try starting the read loop until after the device
is successfully initialized
- add new HID wrapper macros needed by ds3 driver
- add some debug logging to help with troubleshooting
- add button map for DS3
== TESTING
Tested with local build. DS3 init is not working.
== DETAILS
Now that I have a working implementation, it's time to tidy up a bit:
- there was no need for the HID subsystem's object data to have a reference
to the global hid state (since it's global), so removed it.
- refactored the users of that member to use the global state, defining
reusable macros.
- reorganized the information in *.h files
- removing the hid state also made the constructor changes to the hid driver
unneeded, so I reverted those changes.
== TESTING
Confirmed clean build. Haven't tested the build yet to make sure everything
still works, though.
== DETAILS
- Added a new method to the joypad_connection_t interface for
getting a single button
- wired everything into the hidpad driver
- for testing purposes, hacking the top-level joypad driver
so that kpad isn't used
- add a new RARCH_LOG_BUFFER method to verbosity for logging the
contents of a binary buffer (useful for writing/debugging pad drivers)
- fix a few bugs in the wiiu GC pad driver
The button mapping isn't quite right, and I'm not sure what's
going wrong.
== DETAILS
Trying to do weird pad math just wasn't working so I bit the bullet and just
let it allocate all 16 pads in the slot list, then just mark 0-4 as
connected so that the slot allocator would start at 5.
I can see it detect the pad, but no idea if it works. Out of time for
today.
== DETAILS
The gamepad didn't work because I had tried to rename the pad from
'WIIU Gamepad' to 'WiiU Gamepad'.
I added some debug logging and (to cut out a lot of trial-and-error)
discovered that the reason it didn't work was because a bug in a macro
was using the define literally instead of substituting it (so e.g.
the autodetect handler was trying to match 'WiiU Gamepad' against the
literal string 'PAD_NAME_WIIU_GAMEPAD').
- Fixed the macro bug
- Left a minimal amount of the debug logging in place; may come in
handy for someone else.
- Updated wpad/kpad/hidpad to use the define constants
== TESTING
Did a test build and confirmed the gamepad responded.
As discussed in libretro#5357; controller_patcher is now optional. It's
off by default; though this could be changed with a simple makefile
tweak (ENABLE_CONTROLLER_PATCHER ?= 1, perhaps?)
To re-enable controller_patcher; append ENABLE_CONTROLLER_PATCHER=1 to
your usual make command.
controller_patcher was the only user of c++ constructors in the Wii U
port, so you'll need 26a006c in your tree otherwise you will have a
blackscreen on startup.
