Detailed Description

Macro Definition Documentation

JOYBUS_TARGET_N64_PAK_RUMBLE

#define JOYBUS_TARGET_N64_PAK_RUMBLE

(

pak

)

Value:

((struct joybus_target_n64_pak_rumble *)(pak))

Macro to cast from a generic N64 pak to a rumble pak.

Typedef Documentation

joybus_target_n64_pak_rumble_motor_cb

typedef void(* joybus_target_n64_pak_rumble_motor_cb) (struct joybus_target_n64_pak_rumble *pak, bool active)

Callback type for rumble pak motor state change events.

Runs in interrupt context, on the response critical path, so it must return quickly. Mark the implementation with JOYBUS_RAM_FUNC.

Parameters

pak	the rumble pak whose motor state changed
active	true if the motor should be on, false if off

Function Documentation

joybus_target_n64_pak_rumble_init()

void joybus_target_n64_pak_rumble_init

(

struct joybus_target_n64_pak_rumble *

pak

)

Initialize a rumble pak.

Parameters

pak	the rumble pak to initialize

joybus_target_n64_pak_rumble_set_motor_cb()

void joybus_target_n64_pak_rumble_set_motor_cb	(	struct joybus_target_n64_pak_rumble *	pak,
		joybus_target_n64_pak_rumble_motor_cb	callback )

Set the motor state change callback for the rumble pak.

NOTE: Motor callbacks are called from interrupt context, do not perform any blocking operations within the callback.

Parameters

pak	the rumble pak to set the callback for
callback	the callback function
