语音驱动程序 drv_voice.c
语音服务程序 srv_voice.c
1、先运行初始化函数，主要是设置初始音量，并建立一个软件定时器来，以10ms的周期来调用语音播放函数。
1 void srvVoiceInit() 2 { 3 T_SOFT_TIMER_HANDLE hSoftTimer; 4 UINT16 usVoiceVolumeTunerAdjust; 5 6 g_hVoiceDevHandle = osalDevOpen(GEN20_PROTO_VOICE_DEV_NAME); 7 if (g_hVoiceDevHandle == INVALID_HANDLE) 8 { 9 LOG_ERROR_LOG(("srvVoiceInit failed at voice driver open.\r\n")); 10 } 11 else 12 { 13 /* Initialize voice play info structure, must before soft timer started. */ 14 /* TODO: read default voice from EEPROM */ 15 srvVoiSetDefaultVoiceType(VDVT_TYPE_A); 16 //g_tVoicePlayInfo.eSwitchStatus = VPSS_VOICE_IDLE; 17 gVoiPlayState = VPSS_VOICE_IDLE; 18 gVoiInnerEvent = E_NULL; 19 usVoiceVolumeTunerAdjust = 160; 20 //gVoiceToSet = 54; 21 srvSetVoiceVolume(63); 22 osalDevIoctl(g_hVoiceDevHandle, VOICE_CTRL_RST_PLAYBACK_CLR , NULL); 23 osalDevIoctl(g_hVoiceDevHandle, VOICE_CTRL_SET_VOICE_VOLUME, &usVoiceVolumeTunerAdjust); 24 25 /* Create the soft timer for push button service, the handle is not needed. */ 26 if (OSAL_IS_RESULT_OK(osalTimCreateSoftTimer(&hSoftTimer, 10, STT_REPEAT, &srvVoicePlayTimerRoutine, NULL))) 27 { 28 if (OSAL_IS_RESULT_OK(osalTimStartSoftTimer(hSoftTimer))) 29 { 30 g_hVoiceMode = 0; 31 } 32 else 33 { 34 LOG_ERROR_LOG(("srvVoiceInit failed at SoftTimer start.\r\n")); 35 } 36 } 37 else 38 { 39 LOG_ERROR_LOG(("srvVoiceInit failed at SoftTimer create.\r\n")); 40 } 41 } 42 }
2 语音播放函数，先根据状态来设置语音模式，再根据模式来播放语音
1 static void srvVoicePlayTimerRoutine(void *pvParam) 2 { 3 /* Wait event and return immediately. */ 4 if(0 != g_hVoiceMode) 5 { 6 /* Some thing happened, adjust current voice play accordingly. */ 7 srvVoiUpdateVoicePlayInfo(g_hVoiceMode); 8 9 /* Control voice play according to the information. */ 10 srvVoiPlayVoice(); 11 g_hVoiceMode = 0; 12 } 13 else 14 { 15 srvVoiPlayVoice(); 16 } 17 18 }
3 更新语音播放信息，根据语音模式来更新
根据接收的语音事件来播放对应的语音片段，
语音包括以下
SRV_VOICE_PLAY_SYSTEM_START；系统启动声音
SRV_VOICE_PLAY_OPERATION_DENIED；操作禁止声音
SRV_VOICE_PLAY_TEST；测试声音
SRV_VOICE_PLAY_MIN_OUTPUT；小档位声音
SRV_VOICE_PLAY_MAX_OUTPUT；大档位声音
SRV_VOICE_PLAY_OVER_CURRENT；过流警报声
SRV_VOICE_PLAY_RECOVERABLE_FAULT；可恢复性错误声音
SRV_VOICE_PLAY_NON_RECOVERABLE_FAULT；不可恢复性错误
SRV_VOICE_PLAY_FAULT_REPLAY；错误重放
SRV_VOICE_PLAY_SHOW_DEFAULT_VOICE；默认语音
