Microphone service "mic:u"
| Command Header | Description |
|---|---|
| 0x00010042 | MapSharedMem |
| 0x00020000 | UnmapSharedMem |
| 0x00030140 | (u8 unk0, u8 unk1, u32 unk2, u32 offset, u8 unk3) ? (input offset = offset where the offset field is located in sharedmem, normally sharedmemsize-4) |
| 0x00040040 | (u8 input) ? |
| 0x00050000 | ? |
| 0x00060000 | This writes an output u8 to cmdreply indexword[2]. val = *((u16*)0x1ec62000) >> 15. |
| 0x00070000 | GetEventHandle. |
| 0x00080040 | SetControl(u8 input). This is a wrapper for CDCMIC command 0x00010040. |
| 0x00090000 | GetControl. This is a wrapper for CDCMIC command 0x00020000. |
| 0x000A0040 | SetRecording(u8 input). This is a wrapper for CDCMIC command 0x00030040. 0 = disable recording, 1 = enable recording. When recording is disabled with this, MIC-module writes value 0xFFFF to the output audio sample data in shared-mem, since that's what the MIC hardware returns here. |
| 0x000B0000 | IsRecording. This is a wrapper for CDCMIC command 0x00040000. |
| 0x000C0042 | (size, <translate-header>, bufptr) This is a wrapper for CDCMIC command 0x00050042. |
| 0x000D0040 | (u8 input) This writes the input value to a MIC-module state field. |
| 0x000E0000 | This writes the u8 value of the MIC-module field also used by command 0x000D0040, to cmdreply indexword[2]. |
| 0x000F0040 | (u8 input) This writes the input u8 value to a MIC-module state field. |
| 0x00100040 | Initialize |
This is an interface for using the MIC hardware via the "cdc:MIC" service and the MIC IO registers.
Only one session can be open for this service total(that is, only one process can use this service at a time).
