14 | * Wiimote Modules | |
15 | * Nintendo devices provide different peripherals and many new devices lack | |
16 | * initial features like the IR camera. Therefore, each peripheral device is | |
17 | * implemented as an independent module and we probe on each device only the | |
18 | * modules for the hardware that really is available. | |
19 | * | |
20 | * Module registration is sequential. Unregistration is done in reverse order. | |
21 | * After device detection, the needed modules are loaded. Users can trigger | |
22 | * re-detection which causes all modules to be unloaded and then reload the | |
23 | * modules for the new detected device. | |
24 | * | |
25 | * wdata->input is a shared input device. It is always initialized prior to | |
26 | * module registration. If at least one registered module is marked as | |
27 | * WIIMOD_FLAG_INPUT, then the input device will get registered after all | |
28 | * modules were registered. | |
29 | * Please note that it is unregistered _before_ the "remove" callbacks are | |
30 | * called. This guarantees that no input interaction is done, anymore. However, | |
31 | * the wiimote core keeps a reference to the input device so it is freed only | |
32 | * after all modules were removed. It is safe to send events to unregistered | |
33 | * input devices. | |

2054 | * The single bits Yaw, Roll, Pitch in the lower right corner specify | |
2055 | * whether the wiimote is rotating fast (0) or slow (1). Speed for slow | |
2056 | * roation is 440 deg/s and for fast rotation 2000 deg/s. To get a | |
2057 | * linear scale we multiply by 2000/440 = ~4.5454 which is 18 for fast | |
2058 | * and 9 for slow. | |
2059 | * If the wiimote is not rotating the sensor reports 2^13 = 8192. | |
2060 | * Ext specifies whether an extension is connected to the motionp. | |
2061 | * which is parsed by wiimote-core. | |
