== DETAILS
The way the mouse emulation worked was to simply return a 3rd axis from the
gamepad, which the polling code updates with the touch state in real time.
Well, the code that figures out if it's a positive or negative axis was
failing because it didn't see that 3rd axis as valid. So, I added values
which allow it to be seen as valid, and voila! the touch screen input
works again.
== TESTING
Tested locally using "Beneath a Steel Sky" in ScummVM.
== DETAILS
Thanks to JacobM at GBAtemp for helping me test this.
The WaveBird wasn't being properly picked up due to the port status byte
being different from normal GC controllers. (Why? who knows. Probably
so games could detect the WB and show WB-specific OSDs).
This implementation should be more future-proof, to handle any other
unexpected status bytes.
== 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.
== DETAILS
So, it turns out that there *is* a autoconfig disconnect handler. Took digging
through tasks/task_autodetect.c to find it!
So, I added a call to the handler when the pad gets disconnected.
This seems to solve the problem of the pad not disappearing from the menu.
(At the very least, the user's pad index reverts to "none" which is still
an improvement)
== TESTING
Tested manually, made sure it didn't crash or leak slots.
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
So, the GCA has 2 USB connections; one is the data connection, and the
second is used to drive rumble.
Due to a driver bug, if the second cable wasn't attached, the pads wouldn't
get detected.
I fixed that bug.
== DETAILS
I think this will fix the problem with duplicate pads--pads weren't properly
de-initializing and registering as disconnected. When a pad is disconnected,
the slot should properly release now.
retro_bits_t turned into input_bits_t and there were parts of my
code that needed to update.
== TESTING
No idea if upstream changes broke anything, but it compiles cleanly
now.
== DETAILS
TIL that it's bad to call synchronization code from callbacks.
To avoid that, I made the following changes:
- Implemented an atomic swap (see previous commit) to avoid explicit
locking when working with the event list
- ensure locks are only acquired in either the main thread or the
I/O polling thread
- use an explicit polling loop; we still use async reads, but the
read doesn't immediately re-invoke itself.
- remove the sleep in the polling thread.
- remove unnecessary locking in the thread cleanup call--verified that
the list can't be modified while it is being executed.
== TESTING
I tested locally, and was able to disconnect/reconnect USB devices several times without the worker thread getting deadlocked.
Fortunately, the gcc port implements the builtins and, from basic
testing, they seem to work.
This is only really useful on Wii U--other platforms have more
robust atomic operations, or aren't using gcc to build.
== 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
Whereas the last commit had a hack (that disabled the wiimote
driver in the process), this has.. well, a *different* hack that
allows pads to register in any order.
Note that due to the initialization routines, the gamepad will still
likely always get slot 0. Not sure if this can be overridden via config
or not.
== TESTING
Tested locally with GC adapter
== 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
The WiiU GC adapter is working!
Next up: DualShock 3
I have the skeleton of the driver started, need to work out the
activation packet.
== TESTING
The DS3 driver is broke as hell right now.
== 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.
