The data just needs to be something like:
typedef struct
{
float x;
float y;
} VEC2;
typedef struct
{
VEC2 l_stick;
VEC2 r_stick;
float l_shoulder;
float r_shoulder;
uint64_t buttons;
} GAMEPAD_DATA;
That's a complete controller state in 32 bytes. The analog values
in actual hardware are usually actually returned as unsigned byte
values, but from a protocol point of view converting each stick axis
to the range [-1.0f .. 1.0f] and the triggers to [0.0f .. 1.0f] is
saner. If Wayland just delivers that data it will cover most needs.
