| 36 | * Since WiiC is a library, wiic.h is a duplicate |
|---|
| 37 | * of the API header. |
|---|
| 38 | * |
|---|
| 39 | * The code that would normally go in that file, but |
|---|
| 40 | * which is not needed by third party developers, |
|---|
| 41 | * is put here. |
|---|
| 42 | * |
|---|
| 43 | * So wiic_internal.h is included by other files |
|---|
| 44 | * internally, wiic.h is included only here. |

| 104 | * The different codes wrt. to Linux |
|---|
| 105 | * is a bit hard to explain. |
|---|
| 106 | * Looking at Bluetooth CoD format, we have 24 bits. |
|---|
| 107 | * In wiic Linux they are stored in three fields, |
|---|
| 108 | * each one 8bit long. The result number is |
|---|
| 109 | * 0x002504. However, MacOS Bluetooth does |
|---|
| 110 | * not store them in such a way, rather it uses |
|---|
| 111 | * the concept of major service, major class, |
|---|
| 112 | * and minor class, that are respectivelly |
|---|
| 113 | * 11bit, 5bit, and 6bit long. Hence, the |
|---|
| 114 | * numbers are different. |
|---|
| 115 | * The Wiimote CoD Bluetooth division is the following: |
|---|
| 116 | * 00000000001 00101 000001 00 (major service - major class - minor class - format type) |
|---|
| 117 | * This can also be seen in the WiiC Linux way: |
|---|
| 118 | * 00000000 00100101 00000100 |
