基于DSP_CPLD_aP8942A_LM1791的语音控制
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
1 static void srvVoiUpdateVoicePlayInfo(UINT uVoiceEvent)
2 {
