== DETAILS
- the free() method of the hid_driver_t interface needs its
parameter defined as const in order for the compiler to stop
complaining about losing const-ness.
- if a joypad list is created with <MAX_USERS slots in it, the
destroy() function will crash because it assumes there are MAX_USERS
entries.
To do this, the allocate function creates n+1 slots, and gives the
last slot a canary value that the destroy() method can then watch for
when iterating through the list.
== DETAIL
One minor detail missed in the last commit: actually putting the
send_control function into the driver declaration. Woops.
Not doing the Wii U because it will be using the other methods.
== DETAILS
The current HID implementation assumes a very low-level USB library
is being used. This causes a problem on Wii U, because the Cafe OS
only exposes a high-level interface.
To get these functions exposed to the HID pad drivers, I had to make
three changes:
1. I added the legacy "send_control" function to the HID driver
interface
2. I modified the signature of pad_connection_pad_init() to send the
driver pointer instead of the function pointer
3. I updated the HID pad drivers to keep the pointer to the driver
instead of the function pointer, and updated the calls into the
send_control function as appropriate
4. I updated the HID drivers to use the new pad init signature
== TESTING
Untested, in theory it should work without a hitch because at this
point all I've done is abstract things a little. I still need to
update the HID pad drivers to use the Wii U-specific calls as
appropriate.
In order to have a controller working you need:
1) Have a matching HID autoconfig file in autoconfig/hid for your controller.
2) Create a "connect" driver for the pad in "input/connect" folder (source code of RA).
3) Once you are in RA, change the joystick driver to HID and restart.
4) You may be now able to use you USB HID compatible pad in RA.
I included some "connect" drivers as an example. It also need to include them for compilation.
