簡介

在上兩篇文章中，我們實現了GPIO輸出，和PWM輸出(組件介紹在前文中已經介紹過），在本章節我們將繼續進行使用語音指令控制串口輸出。

配置Example默認串口數據輸出

1、首先修改

/home/vc02/Downloads/uni_hb_m_solution/unione_lite_app_hb_m/user/inc/user_config.h

中的USER_RUN_DEMO_SELECT為USER_DEMO_UART

這樣默認運行的程序就是

/home/vc02/Downloads/uni_hb_m_solution/unione_lite_app_hb_m/user/src/examples/hb_uart.c

代碼如下所示

#include"user_uart.h"
#include"user_event.h"
#include"user_player.h"
#include"user_config.h"
#defineTAG"hb_uart_voice"
staticuni_pthread_tg_uart_thread_id =0;
staticboolg_uart_thread_running =false;
// 串口發送線程函數
staticvoid_uart_send_task(void*args) {
charbuf[6] = {1,2,3,4,5,6};
intret;
 g_uart_thread_running =true;
while(g_uart_thread_running) {
 LOGT(TAG,"UART send done, ret=%d", ret);
 uni_msleep(2000);// 每隔2秒發送一次
 }
}
// 創建發送線程
staticResult _create_uart_thread(void) {
if(g_uart_thread_running) {
 returnE_OK;
 }
 thread_param param;
uni_memset(¶m,0,sizeof(param));
 param.stack_size = STACK_SMALL_SIZE;
 param.priority = OS_PRIORITY_LOW;
uni_strncpy(param.task_name,"uart_voice",sizeof(param.task_name) -1);
if(0!=uni_pthread_create(&g_uart_thread_id, ¶m, _uart_send_task,NULL)) {
 returnE_FAILED;
 }
uni_pthread_detach(g_uart_thread_id); // 自動資源回收
returnE_OK;
}
// 停止發送線程
staticvoid_stop_uart_thread(void) {
if(!g_uart_thread_running)return;
 g_uart_thread_running =false;
if(g_uart_thread_id !=0) {
 uni_pthread_destroy(g_uart_thread_id);
  g_uart_thread_id =0;
 }
}
// 語音喚醒命令回調
staticvoid_on_wakeup_cmd_cb(USER_EVENT_TYPE event,user_event_context_t*context) {
if(context ==NULL)return;
event_goto_awakend_t*awake = &context->goto_awakend;
if(strcmp(awake->cmd,"wakeup_uni") ==0) {
  _create_uart_thread(); // 啟動串口線程
 user_player_reply_list_random(awake->reply_files); // 播放語音回復
 }
}
// 自定義設置命令回調
staticvoid_custom_setting_cb(USER_EVENT_TYPE event,user_event_context_t*context) {
if(context ==NULL)return;
event_custom_setting_t*setting = &context->custom_setting;
if(strcmp(setting->cmd,"TurnOn") ==0) {
  _stop_uart_thread(); // 停止串口線程
 user_player_reply_list_random(setting->reply_files); // 播放語音回復
 }
}
// 注冊語音事件回調
staticvoid_register_event_callback(void) {
user_event_subscribe_event(USER_GOTO_AWAKENED, _on_wakeup_cmd_cb);
user_event_subscribe_event(USER_CUSTOM_SETTING, _custom_setting_cb);
}
// 主入口
inthb_user_uart_voice_control(void){
if(0!=user_uart_init(NULL)) {
 LOGE(TAG,"UART init failed");
 return-1;
 }
 _register_event_callback();
return0;
}

其默認行為為創建線程定時發送數據，然后使用LOG打印。但是它沒辦法調試。因此我們做一點簡單的修改，當接受的數據的時候再發送出去。

// 串口發送線程函數
staticvoid_uart_send_task(void*args) {
charbuf[6] = {1,2,3,4,5,6};
intret;
 g_uart_thread_running =true;
while(g_uart_thread_running) {
  LOGT(TAG,"Voice triggered UART send [1, 2, 3, 4, 5, 6]");
  ret = user_uart_send(buf,sizeof(buf));
  LOGT(TAG,"UART send done, ret=%d", ret);
  uni_msleep(2000);// 每隔2秒發送一次
 }
}

2、編譯和燒錄

實驗現象：串口以9600的波特率持續接收到數據 01，02，03，04，05，06 和程序中的數據對應，正確無誤。

發送測試：之后嘗試向其發送數據，查看VC-02是否能正常轉發回來（關閉HEX顯示，發送的數據和接受的一致）。

使用語音命令控制串口發送數據

1、創建文件

hb_user_uart_testing.c在/home/vc02/Downloads/uni_hb_m_solution/unione_lite_app_hb_m/user/src/examples下

#include"user_uart.h"
#include"user_event.h"
#include"user_player.h"
#include"user_config.h"
#defineTAG"hb_uart_voice"
staticuni_pthread_tg_uart_thread_id =0;
staticboolg_uart_thread_running =false;
// 串口發送線程函數
staticvoid_uart_send_task(void*args) {
charbuf[6] = {1,2,3,4,5,6};
intret;
 g_uart_thread_running =true;
while(g_uart_thread_running) {
 LOGT(TAG,"Voice triggered UART send [1, 2, 3, 4, 5, 6]");
  ret =user_uart_send(buf,sizeof(buf));
 LOGT(TAG,"UART send done, ret=%d", ret);
 uni_msleep(2000);// 每隔2秒發送一次
 }
}
// 創建發送線程
staticResult _create_uart_thread(void) {
if(g_uart_thread_running) {
 returnE_OK;
 }
 thread_param param;
uni_memset(¶m,0,sizeof(param));
 param.stack_size = STACK_SMALL_SIZE;
 param.priority = OS_PRIORITY_LOW;
uni_strncpy(param.task_name,"uart_voice",sizeof(param.task_name) -1);
if(0!=uni_pthread_create(&g_uart_thread_id, ¶m, _uart_send_task,NULL)) {
 returnE_FAILED;
 }
uni_pthread_detach(g_uart_thread_id); // 自動資源回收
returnE_OK;
}
// 停止發送線程
staticvoid_stop_uart_thread(void) {
if(!g_uart_thread_running)return;
 g_uart_thread_running =false;
if(g_uart_thread_id !=0) {
 uni_pthread_destroy(g_uart_thread_id);
  g_uart_thread_id =0;
 }
}
// 語音喚醒命令回調
staticvoid_on_wakeup_cmd_cb(USER_EVENT_TYPE event,user_event_context_t*context) {
if(context ==NULL)return;
event_goto_awakend_t*awake = &context->goto_awakend;
if(strcmp(awake->cmd,"wakeup_uni") ==0) {
  _create_uart_thread(); // 啟動串口線程
 user_player_reply_list_random(awake->reply_files); // 播放語音回復
 }
}
// 自定義設置命令回調
staticvoid_custom_setting_cb(USER_EVENT_TYPE event,user_event_context_t*context) {
if(context ==NULL)return;
event_custom_setting_t*setting = &context->custom_setting;
if(strcmp(setting->cmd,"TurnOn") ==0) {
  _stop_uart_thread(); // 停止串口線程
 user_player_reply_list_random(setting->reply_files); // 播放語音回復
 }
}
// 注冊語音事件回調
staticvoid_register_event_callback(void) {
user_event_subscribe_event(USER_GOTO_AWAKENED, _on_wakeup_cmd_cb);
user_event_subscribe_event(USER_CUSTOM_SETTING, _custom_setting_cb);
}
// 主入口
inthb_user_uart_voice_control(void){
if(0!=user_uart_init(NULL)) {
 LOGE(TAG,"UART init failed");
 return-1;
 }
 _register_event_callback();
return0;
}

輸入上述代碼，其主要的業務邏輯就是通過喚醒命令來觸發串口的定時輸出，然后通過TrunOn的命令來關閉串口輸出的線程。

2、添加編譯支持在

/home/vc02/Downloads/uni_hb_m_solution/unione_lite_app_hb_m/build/user/src/examples下的subdir.mk添加對當前編譯文件的引用。
