【平头哥RVB2601创意应用开发】为webplayer播放例程增加串口调节音量 [复制链接]

 

只需要将player_demo中的cmd_ipc_func函数修改为如下即可：

static void cmd_ipc_func(char *wbuf, int wbuf_len, int argc, char **argv)
{
	uint8_t vol_temp;
    if (argc == 3 && strcmp(argv[1], "play") == 0) {
        char url[128];
        if (strcmp(argv[2], "welcom") == 0) {
            snprintf(url, sizeof(url), "mem://addr=%u&size=%u", (uint32_t)&_welcome_mp3, _welcome_mp3_len);
            player_play(get_player_demo(), url, 0);
        } else {
            player_play(get_player_demo(), argv[2], 0);
        }
    } else if (argc == 2 && strcmp(argv[1], "stop") == 0) {
        player_stop(get_player_demo());
    } else if (argc == 2 && strcmp(argv[1], "volup") == 0) {
		player_get_vol(g_player, &vol_temp);
		printf("Original Vol:%d\n",vol_temp);
		if((vol_temp)<=245)
			player_set_vol(g_player, vol_temp+10);
		player_get_vol(g_player, &vol_temp);
		printf("Current Vol:%d\n",vol_temp);
    } else if (argc == 2 && strcmp(argv[1], "voldown") == 0) {
		player_get_vol(g_player, &vol_temp);
		printf("Original Vol:%d\n",vol_temp);
		if((vol_temp)>=10)
			player_set_vol(g_player, vol_temp-10);
		player_get_vol(g_player, &vol_temp);
		printf("Current Vol:%d\n",vol_temp);
    } else if (argc == 2 && strcmp(argv[1], "pause") == 0) {
        player_pause(get_player_demo());
    } else if (argc == 2 && strcmp(argv[1], "resume") == 0) {
        player_resume(get_player_demo());
    } else if (argc == 3 && strcmp(argv[1], "web") == 0) {
        g_url = strdup(argv[2]);
        LOGD(TAG, "g_url = %s", g_url);
        aos_task_new("web_task", _webtask, NULL, 6*1024);
    } else {
        printf("\tplayer play welcom/url[http://]\n");
        printf("\tplayer pause\n");
        printf("\tplayer resume\n");
        printf("\tplayer stop\n");
		printf("\tplayer volup\n");
		printf("\tplayer voldown\n");
        printf("\tplayer help");
    }
}

使用方式：

player volup 增加音量

player voldown 降低音量

一次增加或减少10个单位。

 

在串口中使用命令会显示如下：
